Waterproofing concrete and basements
My cinder block wall was seeping water, so I sealed
it with Drylock. But after several months, efflorescence pushed it out and it blistered and peeled. I cleaned
the concrete and painted it again two times, but it always peeled and leaked again. Then, I tried your RadonSeal.
It pushed out rivers of efflorescence from the concrete and it is now bone-dry. Thanks,
Brian D., NC
You have a customer for Life! I am a contractor and had a property with a water issue in the basement. The water was actually puddling in the middle of the room, coming up from under the concrete floor. I used the Radon seal and to my amazement ... no more water in fact no more moisture! That was 5 years ago and still no problems. Your product does exactly what you claim. Thank you on behalf of my customers and myself.
Tom F., Atlanta, GA
I HAD WATER SEEPING THRU CONCRETE FLOOR WHEN RAINING. I HAD TWO ESTIMATES FROM WATERPROOFERS. THE FIRST ONE SAID APPROX. $6,000 AND THE SECOND ANYWHERE FROM $3,000 TO $16,000. SEARCHING THE INTERNET, I FOUND RADONSEAL. I WAS SKEPTICAL BUT ORDERED IT. AFTER APPLYING IT APPROX. 1 YEAR AGO, IT STILL IS WORKING GREAT. NO WATER SEEPING OR DAMP SMELL. THANK YOU!

I want to thank you for your products. i had two big cracks in my poured foundation which I had to fix because we decided to make use of our basement as a living area.
But first i want to tell you about some of many companies that came to my house to see the problem. One company advertises that you will never have water in your basement again. Well that sounded like just what i needed. No more problems ever. So I called, they inspected the two cracks and gave me an estimate of $5,000. They would run a drain thru the middle of my basement and just let the water run thru the walls and this way, I will never have a water problem again! Well, now I said that your ad doesn't state that my basement was going to have a waterfall on the wall!
Then, I saw your site on the Internet and read everything you had on there. I must say you guys know what you are talking about. When you tell me no more water you really mean it. I decided to that two 5 gallon pails of RadonSeal at a $179 each was a whole lot cheaper than the last guys' waterfall project. Ha! Ha! Because I had the two cracks I went a head and also ordered your crack sealer kit. WOW! WHAT A BLESSING IN A TUBE for a $125 each and a total of $429.
Well, I did everything you said to do. When I got done, I thought now we have to wait for a heavy rain to see if we did what we intended to do STOP THE WATER. Well, it started raining here in the spring and it rained for 8 strait days and I mean heavy rains. Everybody's basement was getting wet that normally didn't get wet. But my basement was high and dry! YES! We beat the big company with his waterfall business.
I just want say to you THANK YOU GUYS FOR SUCH A GREAT BUNCH OF PRODUCTS that really do work and the cost is nothing to what the big companies want. Oh well, got to go down and catch a good movie on the big screen. Thanks again.
Everett W. B., NY
I used the Radon Seal on an 80 year old cement floor in a basement to try and stop ground water seepage. It works great! There is no more water seepage thru the floor. Unfortunately, that water has now found an outlet thru one of the basement walls. If you have any suggestions (that waterproof paint doesn't do diddly!), I'd appreciate it. I've recommended your product to several people as everybody around here has an 80 year old cement basement. It' really works. Thanks!
Rebecca G., NJ
You should know that the RadonSeal worked great on my koi pond several years ago. It's a vinyl lined pond but with a lot of concrete on the bottom (over the liner) to hold rock in place. The leaching lime will raise PH a lot and causes algae problems. I sealed it twice with RadonSeal but could only allow it to dry for 12 hours with fans running. It definitely worked - my PH dropped the next day and remains in normal range for the past 4 years. You should put this application on your website as many pond owners have the same issue. I had a very hard time finding any product that was fish safe.
Mike K., IL
I had to fix a crack in my poured cement basement wall. It is a very small, hairline crack that runs the height of the wall (about 8 feet). I was getting a small amount of water seeping through the crack after heavy rainfall.
Radon Seal selaer solved the problem all by itself – what a great product! Things are thawing up here
now and we've had a couple of bouts of heavy rainfall, but I am not getting any seepage through the crack
at all.
Joe D., MI
I used radon seal to seal my concrete ponds and a waterfall that I built in my backyard. I had filled it without a seal and it seemed to let the water seep out. I then used Radon Seal and it sealed the ponds and we used the waterfall all summer with no seepage. I think that Radon Seal is a great product and the people that I spoke with before I sealed the ponds were very helpful and knowledgeable about sealing concrete.
Thank you for your help and product.
Bill D., CA
I was putting off finishing my basement because of water issues. All of the tie holes were not filled in properly and even after patching them, I still had water puddling up every time we had a big rain storm.
I applied a bucket of RadonSeal on two walls to see how well it worked. After several months and multiple heavy down pours no water has appeared. My wife and are are very impressed with the product so I just bought another bucket of RadonSeal to seal the other walls. I highly recommend your product and can't wait to get going on finishing the entire basement now that I know there will be no more water issues.
Thomas M., MA
I have been very happy with RadonSeal. I used it on the basement floor of a
house we have built at Cape Cod, and have found it to be excellent for curing and then,
sealing concrete. I have been building houses for years but have never seen or heard of any other product
that could compare to it! I would highly recommend it.
Donald N., MA
As a general contractor who recently used Radon Seal and Ion Bond Armor to
resolve a serious water infiltration problem, I must say I am 110% impressed
with your products. We tried other sealers but they did not do the job and were a pain to remove.
Justin G., MA
I am selling my house and one of the major points of interest to the buyer is "Does the basement
leak"? I have had my house up since last September. Since I put it up for sale, I have tried
Drylock, ThoroSeal. Locktite, and Rockite. None of these products worked. I always had to say "Yes,
I get water in the basement." I applied your product Ion-Bond Armor on
Saturday morning and on Sunday and Monday it rained all day. I was so pleased when I checked Monday morning
and found no water, but I said since it is going to rain all Monday, I will check when I get home from work.
Well, to my delight there was no water when I got home from work. I can't tell you how pleased I am with
your product.
Rose E. K., OH
I wanted to let you know how great your product is working for our concrete roof here
in Texas. We had some small cracks on 1 1/2" concrete roofs, which were poured over a rubber membrane.
The rubber membrane had some holes letting small drips of water into the house. We used your Ion-Bond
Armor on the concrete and Wow! Not a drip in site! It does what it says it will do and we highly recommend
it! After a rain the water just beads up and rolls off the roof. In fact, we are ordering 2 more 5 gallon
buckets to use on the other roofs of the house just to be safe.
Finally a product worth buying!

Sealing damp basements against moisture and molds
I am finishing my basement and had great concerns about damp basement air, mold and mildew, and of course radon. Particularly, since we have a newborn in the house. When I received RadonSeal, I was skeptical of its effectiveness like any customer would be. I found it quick and easy to apply. Before I knew it, I was done with two applications. I was concerned about fumes because of my newborn, but there really weren't any.
My radon is now very low and the basement feels dry. I did have a water spillage on the floor recently and noticed the water did not penetrate or absorb, it just stayed there until I wiped it off. I do not have to worry about damp basement anymore thanks to RadonSeal!
Mark W., MA
P.S. I will now recommend RadonSeal to all my friends and neighbors.
My basement was basically a big open concrete slab floor and block wall room. There had been a bit of minor water damage/seepage but no apparent major flooding. I did a little research on the Net and found a product called RadonSeal (www. radonseal .com ). It's a liquid sealer that is sprayed on concrete that soaks into the block and dries to form a plastic-like barrier. I bought 2 5-gal buckets and sprayed the hell out of my basement before I started any remodeling. I could immediately feel a difference in the dampness in the air. Within a day or so, the dehumidifier I have was extracting less than 1/4 of the moisture it had before. I put 3-4 coats on the block walls and 3-4 coats on the slab floor. It works like a charm.
Pat McD., OH
As for the "amazing results" on our 100 year old basement walls ... before RadonSeal, our walls were literally crumbling, the basement smelled terrible and there was mildew everywhere. We striped the paint off the walls in the main room, sprayed on the RadonSeal Plus and have had no crumbling or water related problems for over 3 years. We just ordered another pail of the RadonSeal Plus to finish 3 smaller rooms in the basement before we sell the home. Based on our experience in the main room of our basement, we know sealing up the remaining walls with RadonSeal will help us sell our home because the basement will look and smell better.
Cathleen B., ME
I have always had a musty and damp basement and having two very allergic young children to mold and mildew this worried me. In NJ we have had tremendous rainfall this past season and I knew I had to do something quick.
I applied your Radon seal on the cinder block as directed and have not had any dampness in the basement anymore, I cannot thank you enough for having a product that says what it does. Your service was excellent and very patient in answering all my concrete questions before helping me place my order.
Ken L., Edison, NJ
Want to let you know that the Radonseal penetrating sealer you sold me has done a great job! The basement is noticeably less damp, the musty smell is nearly gone, and the leaking hairline floor slab cracks are no longer wet.
I also used your crack injection sealer and it completely stopped rainwater leakage from the crack in my 10 inch thick poured basement wall. I really commend your attempt to keep your products user friendly while developing materials that tackle so many difficult concrete challenges. Rarely have I found such an instructive and insightful website. I have already recommended your products to several other friends based on the immediate successes I have had.
Hugh B., NY
Just wanted to send a quick note on how impressed I was with the RadonSeal product. We bought a new home that had the basement already finished. Unfortunately, the relative humidity in the basement rooms would constantly hover between low 80% to high 70%. The rooms acquired a definite “musty smell” especially when they had been closed up. We bought a heavy duty dehumidifier that would handle 70 pints per day, and the poor machine worked endlessly to hold the humidity level to 50%.
After finding your website, (one of the most useful websites I have come across), I reluctantly decided to pull up the carpet and purchase your RadonSeal Standard for the concrete floors. Wow what a difference!!!! - - - Since applying the RadonSeal on any exposed poured concrete wall that wasn’t finished and the entire concrete floor, the relative humidity is holding at 44 to 46% without the use of the dehumidifier! I’m sold! I’ll be sure to recommend your product to anyone that has a similar problem.
By the way, thanks for your patience in answering my other questions when I called back about sealing large cracks, sealing around the area between the wall/floor, etc. Your customer service is as good as your product and that’s saying a lot!
Thanks again,
Jim M., GA
I purchased RadonSeal to prevent moisture build-up in my finished basement, but I ended up with a very pleasant surprise. Last year, we purchased a 28 year house in rapid decline and went about restoring it. We found & repaired several issues with the foundation, but a nasty smell remained. As it was a daylight basement, we opened the windows and “aired out” the
basement every chance we could, but the smell remained, even 6 months later. Even so, we still planned to
finish the basement.
Not giving it much thought, I bought RadonSeal as prevention for Radon and to prevent
moisture buildup between the foundation and finished walls. However, the next day we went downstairs and like
magic – that mildew smell for months?? GONE!! Completely and totally gone!!
We had contractors and family all helping during the restoration – everyone knew about the ‘bad smell’ in
the basement to the point of questioning why we wanted to finish it. NO ONE could believe the immediate change.
I am happy to say, the basement has been finished for almost 1 year now and we have had no problems with moisture, radon, or that nasty, musty smell.
I was so happy I am buying more to use in my newly built garage as a floor primer before I put down the epoxy covering.
I am very happy – and would be a reference to anyone considering using it!
Thank YOU!
R.W., Olathe, KS
Several years ago, I applied your Radonseal to a portion of my basement to create a pantry area for food, clothing and valuables. While my basement had never leaked, the constant flow of moisture vapor through the floor caused that well known musty/concrete smell and mildew to form on anything stored for long.
After letting RadonSeal set for a few weeks, I covered the floor with linoleum tile using standard mastic. I'm happy to report that after over 8 years, the pantry has been dry clean with no musty smell or mildew on anything stored there. The tiles have stayed absolutely flat and secure and bone dry.
As a guy who is very skeptical of product claims, I've verified it works, and works very well. Thanks for making a great product, and one that gives the added (and even more important) benefit of blocking dangerous radon gas.
Chris H., NH
My basement is poured concrete from 1910. The walls are 14". The basement had very high humidity, with damp spots on the walls and floor, and was always musty and moldy. My wife complained regularly about the smell in our house that was coming from the basement.
We excavated, put in weeping tile, insulated, and waterproofed from the outside, but the musty smell and mold was still there along with damp spots on the walls, and floor. This cost us $10,000.
I ordered 2 pails of Radon Seal Plus, and applied them. I am completely impressed with it's performance. The basement is very dry now. The musty mold smells are gone, and I am finally going to finish the basement.
Thank you RadonSeal!
D.D., Grand Portage, MN
I used RadonSeal Plus to waterproof small areas of my poured concrete cement foundation that were damp, spalling and causing a musty odor in the basement. The house was built in 1933 and the walls were originally painted with calcimine then CalciCoater. There are bare spots where the moisture has lifted the paint. I poured RadonSeal into a bucket and used a paintbrush to cover the bare areas with excellent results. There is no sign of spalling or moisture and the odor is gone. I found RadonSeal easy to use and I was pleased that it was non-toxic and environmentally safe. Thank you for such a fine product.
Susan D., MA
We ordered radon seal and applied to the basement walls and floor over 1 1/2 years ago. Up until that point
the basement was a mess. The floor seeped and the walls leaked. After finding
your product on the Internet, I ordered it and my husband applied it. The application was so easy – just sprayed
with a garden sprayer. Snce then, the basement has been dry, the musty smell is
gone. Now we have sheetrock up, the walls painted, wiring done, and this is going to be a safe bedroom to
sleep in during storms since we are prone to tornados here in Oklahoma.
Thank you for such a wonderful product!
Alice C., OK
I have a 30 yr old contemporary house with a poured concrete foundation and basement floor. One corner of the basement contains a finished study/media room with a carpet and pad directly on the concrete floor. The room always had a strong smell of mold and dampness. My wife would not watch TV or listen to the stereo in this room!
I found RadonSeal via a web search and was impressed by the content and completeness of the web site. The user comments seemed to be genuine, unlike some other sites I have encountered. Deciding that the product seemed to be worth a try, I placed an order for Radon Seal Plus. I then removed the old carpet and pad from the room and discarded them. After scraping and grinding off most of the old carpet adhesive, I applied the Radon Seal Plus and then, had a new carpet and pad installed. After 8 months, including a lot of wet summer weather, there is no evidence of any damp or moldy smell in this room - this product really does work as advertised!
Mark S., MA
I sealed my entire basement. I am very impressed! Radonseal has done a wonderful job on the moisture problem. I have a dehumidifier and it doesn't even run any more. Before radonseal the basement smelled damp and had water spots. Now it doesn't smell musty or have any water at all. It is nice and dry! Thanks so much for Radonseal! Sincerely,
Karmen K., MI
Living near the ocean has caused major moisture and mildew problems in my basement. With my dehumidifier going full time I was still having a problem. After some research I decided to give Radon Seal a try. This was the best decision I've made in some time. After purchasing ten gallons, following your prep rules to the letter and applying two coats, the change was amazing. Within two days I was noticing a change. In two weeks my humidity index was reading a constant 35 to 40 percent.
Thanks for offering such an excellent product.
Jim H., RI
Hello – Thank you for making this product available. Our basement smells clean and fresh now, after all the scrubbing and applying coats of Radonseal, and the surface seems harder and truly SEALED. We are using Radonseal to seal out moisture (not radon) which is our big problem in the northwest. The rainy season is just beginning here so I’ll let you know now it works as the winter goes on.
Glenda G, Norland, WA
P.S. Building codes should require this type of treatment on all new concrete and blocks, if prevention of problems was considered important.
Just wanted to let you know that the Radonseal product solved my basement dampness problem better than I expected. Our new home in Pike County, PA doesn't have gutters installed yet and all the rain of the past few weeks left large puddles all around the foundation. Before I applied Radonseal the basement walls were very damp. You could actually feel and smell the dampness. A few weeks after I applied the two coats of Radonseal I noticed that not only had the dampness on the walls disappeared, but the musty odor was gone. I have a few gallons left over and plan to apply it to the inside of the garage too. This is a great product!
Frank D., VT
My wife and I decided to finish our basement and we wanted to seal it first. After much research, I chose your RadonSeal Plus. My contractor is glad I did. He will be recommending this product to all his future clients! It's easy to apply and has no odor. It's safe! We have a small child, another one on the way, and pets. The product's qualities were very important to us. It's user friendly, environmentally safe, seals out water and gases, prevents mold, and has a 20 year guarantee! You certainly cannot ask for more in a product and we are extremely happy with it.
Frank H., CT
I just wanted to send an email to thank you for your wonderful product and service. I had a huge problem
with moisture and crumbling walls in my 100 year old poured
concrete basement. I purchased the radon seal plus, applied it to my walls and have had no moisture or crumbling
since the application (and it has been raining for days here!!) Your staff was VERY helpful and responsive
to all of my questions and I really appreciate that. Thanks again!
Bethany B., IN
We would like to thank you for your great product and service. We planned to finish our basement with laminate
floors. But we heard a lot of stories about the problems of laminate flooring "peaking" due
to excessive moisture in the basement. Although our basement is only two years old, the "white powder" could
be seen on some walls, and it always smelled musty when we went to basement. Before finishing it, we applied
RadonSeal Plus to the entire basement. Now it has been two months, there is no more "white
powder" coming out from walls and there is no more concrete smell. Thanks!
Cheryl X., IL
Thank you so much for such quality products. My crawlspace wasn't encapsulated & moisture barrier not applied 100%. Some the ductwork had condensation & mold was noted on the floor joists. After much research, I decided to use your products. The RadonSeal Plus was suggested for my cinderblock foundation areas, Lastiseal for the brick areas & BioZap for the mold removal & future prevention. The application process for the RasonSeal and Lastiseal almost sounded too good to be true (using a garden sprayer) but I was pleasantly surprised. The BioZap is also working well to remove the mold & I am spraying the areas for prevention of further mold. Doing most of this work ourselves has paid for the products & we hope sealing the foundation with your products and doing the other things will eliminate the need for a dehumidifier, which my husband did not want. I have already been recommending your products to others.
Sylvia B., NC
RadonSeal works really really nice. My mortar joints have gone from crumbling
to solid, my floor has gone from damp to dry, the musty
odor is gone, and piles of minerals have been exorcised from the walls and floor. I'm going to use
it on the exterior of my foundation to seal it up nice and tight. Excellent product!
Paul D., Manitoba
I have applied the radon sealer couple years ago. The floor in my shop used
to get wet from condensation every spring. It has worked GREAT! I have a dry
floor year round - thank you.
Rick R., Grand Rapids, MN
I have lived in my present home for 10 years. For some reason my garage floor recently
started to sweat. I found out about Radon Seal on the internet and ordered a 5 gallon pail. In Arkansas
the humidity is always very high and I was having a moisture problem in my garage. The walls were starting
to show signs of mold and the floor was very wet on certain days. After I used Radon Seal (about 2 months
ago) I have had "no" problem with moisture. I have cleaned the walls for mold and repainted my
garage. It looks just like it did when the house was new.
Your product works great and I am so glad!
Thank you.
Robert A., AR
Sealing basements against radon
Hi, I just wanted to send you a thank you note. I applied (4) coats of the RadonSeal Plus to the block walls and (2) coats to the floor of my very damp basement. In the past the walls were always wet at the bottom and there was always a small amount of standing water at the base of the walls. After the application I had a whitish powder which I was able to wipe away. Within days, I no longer had any standing water or wet walls. The radon test results came in today with great results. The level went from 5.1 pCi/L to 0.3 pCi/L.
Thank You very much, your product was easy to use and seems to work like a charm. I will recommend your product and contact you with any future needs that I might have.
Sincerely,
Traci T., DE
I recently purchased two pails of RadonSeal to help lower my Radon level of 3.7 pCi/L recorded in my basement even though I live in an area of Tennessee where EPA feels Radon levels are low. The basement had high humidity levels with water seepage with standing water on some parts of the 1600 sq.ft. I applied three coats of RadonSeal and two days later recorded Radon levels of 1.0 pCi/L. My water seepage and standing water problems disappeared. Needless to say I am very pleased with RadonSeal and would recommended this product.
Sincerely,
Rick D., TN
Hello,
We love your product--our basement has been dry for 2 years and just passed a radon test for the buyers of our home. (We didn't bother mentioning that it had failed one, some years back.)
Elisabeth L.J., NJ
Purchased a 6 year old house with radon level of 64 pCi, prior owner will not reduce or correct. In Pennsylvania (South Central). Floor is poured slab, about 2600 sq feet, walls are block, some signs of moisture, no actual drips.
After RadonSeal, I saw a drop in Radon (using 72 hour electronic monitor) from 64 pCi to 2 pCi! Of course I did seal all cracks with a polyurethane made for expansion joints and cap the sump pump. .... Painted some of the wall - easier than I'm used to with block and greater spread (area wise). Have not tiled floor yet, but I am beginning to think I might get away with not installing a subfloor and just lay tile right on concrete. Thanks RadonSeal!
John D., M.D., PA
We just checked radon this past week, and our basement now is reading 2.0, checked at 2 different locations. Not bad for starting at 29 pCi/L! The house has been closed up, .... I have the drains covered with plastic, but not sealed, and still have the low reading.
Andrean L., IL
Well I didn't believe it at first, but your Radonseal worked like a charm! I have a concrete floor and cinder block walls in my basement. I used 3 pails of Radonseal, primarily because the cinder block is so porous ...I dropped the radon reading from 18 to 0.7.
Bob G., NY
what a great product!! my wife and i live in in a salt box house with a partial basement built on ledge. when we purchased our house this summer we had a radon test done. the results were discouraging as they came back at 3.6 pci/l, which is .4 under the suggested limit but its still cancer causing. after a lot of research, we bought your product, radonseal. although we were somewhat skeptical, we thought we'd give it a try as opposed to a costly radon mitigation system we would have to install on the verge of winter. we sprayed on Radonseal, bought another radon test kit and awaited the results. lo and behold, we dropped the level of radon to 0.1pci/l!!! thanks so much, we've already been recommending to others!!
Scott S., NH
We sold our house and before the closing bought a new one. Then came the bad news that our old house tested for radon at 5.6! ... we found RadonSeal. I sprayed it on right away and asked the inspector to test again. To his surprise, the radon level was now only 1.8! It cost us only $360 and the sale closed at the original price.
Ray P., IA
We applied 5 gallon of RadonSeal to a 26x32 basement floor prior to carpeting. The reading was twice the recommended safety level (8.2 pCi/L) prior to applying the seal. We applied the seal, installed an electronic permanent tester and the radon reading is now 0.2! We are happy with the results. Your office was very helpful. Thank you.
Paul S., VA
One year ago, we bought a ten year old house with an unfinished basement. We also bought a radon detector and checked the radon level in the house before closing. The radon level was at 3, an "acceptable" level. This summer, while organizing the basement, I ran across the radon detector again. I plugged it in and the alarm kept going off because the radon level had risen to 4.
We immediately began researching radon mitigation methods on the internet and came across RadonSeal's website. Their product sounded intriguing, so after several more hours of research, we purchased it.
Like the company said, it was really easy to apply (once we figured out how to open the bucket). Seriously, the hardest part of the whole process was picking up all of the kids toys so we had a bare floor to spray the sealer on.
We applied it a month ago and our radon level is already down to 1, even though we couldn't do the entire basement because one end of it is currently being used for storage, and there's a big pile of lumber on the other end. We are planning to finish applying the RadonSeal when we have access to all of the walls.
Brooke S., MI
We found a nice house, but before closing the home inspector measured radon at 9.5 pCi. We negotiated a $1,000 credit for radon mitigation. Then, we discovered RadonSeal ... It was quick and easy. We have reduced radon from 9.5 down to 1.6 pCi! The 2 pails of RadonSeal cost us $400 and we have earned $600 for a couple of hours of work!
Joe M., PA
My father-in-law suggested that I should share my success with your product. My results were very similar to his. I covered the walls and floors of my basement with RadonSeal in two coats. We have gone from radon measurements around 18 pCi to a consistent long and short term reading of 2. I couldn't be more pleased, and I feel that I got an excellent value compared with other options I have heard about from friends and neighbors.
Jonathan P., IL
I recently moved to my current address and the radon tests showed a 3.5 reading. I did some research and found RadonSeal. I have to say I was very skeptical of the effectiveness of RadonSeal. Since I dislike the idea of installing a fan-based mitigation system, I decided to give a RadonSeal a try given it has a money back policy. To my surprise, the two tests after applying RadonSeal came back both well below 2.0. I am very pleased to say the least!
I highly recommend RadonSeal because it works!
Ray P., MA
I recently purchased your RadonSeal for my basement floors and walls. My radon has dropped from 8.4 to 3.1. I Just wanted to say "good product"! I am a carpenter I will surely tell my friends how well it worked. THANKS,
L.H., NY
I had previously tested at 4 pC (units?) of radon, the threshold for recommended remediation. After treatment, the measure was less than 1. I am pleased with the results! Regards,
Richard T., PA
I wanted my husband to finish the basement but insisted on testing for radon first, because our son would sleep there. The test came out at 4.3 ... I sprayed it on and my husband caulked one Saturday morning. We have just received our radon results yesterday. The radon has dropped to 1.4 and we have saved $800!
Jaime V., CT
I purchased 2 five gallon pails of RadonSeal and applied them to my basement floor and walls. Prior to the application, the radon level was 7.1 (pCi/L). The following week I tested again (in two separate locations) and the level was reduced to 1.6 (pCi/L) even when the instructions indicated that the RadonSeal reaches its full strength in 30 - 60 days! Not only was the product effective at reducing the radon level, it was also very easy to apply and much less expensive than other radon mitigation methods.
Plus, I am in the process of finishing the basement and now have the added assurance that the basement has been waterproofed! Although initially I was skeptical, based on my experience, I would recommend RadonSeal as an effective means to radon mitigation and waterproofing. Thanks RadonSeal!
Robert L. H., CT
After getting a radon reading during my home inspection of 3.8 with spikes up to 5.9, I bought an electronic radon detector and ordered 4 pails of radon seal for the walls and floor. My radon detector registered 4.8 pCi/L before the application. After 2-3 coats of RadonSeal the reading had dropped to 1.8 where it has consistently remained for the past month. Thanks RadonSeal!
Wayne, Raleigh, NC
LastiSeal color stain and waterproofer
I just ordered more of your LastiSeal colored sealer to touch up our floors where we previously applied your product. Everyone who has seen our floors, bar none, cannot believe that they are concrete! I scored the floors with a diamond saw prior to applying the sealer. My wife used a sponge to
texture the sealer and everyone thinks that the floors are natural stone. Actually, we decided to stain the floors due to running low on our budget but now my wife says that if she could have any flooring available, she would choose your sealer.
I used a gallon of LastiSeal Stain outside on part of our porch. I also purchased a cheaper penetrating stain to finish
it (3 coats v. 1 coat of yours). Now when it rains it is clear that your product is far superior by observing the water
penetration. Gentlemen, I am sold on your product and it is the only one I can recommend!
Morgan P., IN
I
know, I'm not too quick on the response, but I am pleased with the result after having the LastiSeal
Concrete Stain on for a few months now. I converted part of my covered patio for a cycle garage,
(attached photos) and it came out so well, I will be doing another section of the patio. Oil
spills are
just wiped up, and tire marks don't show at all.

We wanted to drop a note to tell you,we think that you have WONDERFUL products. We had some major cracks and spaces between our slabs of cement on our backyard patio. Some of the cracks had been filled with tar many years ago,and some with other crack fillers currently on the market today. We needed to clean those products out of the cracks, so we ordered your Lightning Strip Paint and Mastic cleaner and were Very impressed. It just melts the tar and and cleans it off with a wire brush and water.
Next we ordered the ElastiPoxy Crack Filler. In the deeper cracks,we filled
with sand as Joe in Sales had suggested.
When all the cracks
had been filled, our next step was to clean it thoroughly with the Novion Universal Cleaner. That product along with the power washer, did a super job and for the first time ever the patio was several shades lighter as all the dirt and stains were washed away. It is environmentally safe too as your Web site states, as it didn't hurt our grass at all.
After letting it dry out for several days, we applied our first application of LastiSeal Concrete
Color Stain. We used the Dark Gray for the first application and then applied Slate Green on the the diamonds.
By Brush and Roller we applied a 2nd coating to each diamond in the appropriate color. Then finally we applied LastiSeal
Concrete and Brick Sealer in the Satin Finish. The cement is REALLY sealed so nicely and feels great when you walk
on it. Also water just runs off. Amazing!! We are thoroughly pleased with the Finished product and want to Thank
Joe in Sales, for his patience and willingness to help with the many questions that we had for him the several times
we called you.
Radon Seal is to be commended for serving the public with these AMAZING products. We would certainly recommend these products for any concrete products that you want sealed and looking great!!
From your truly happy customers,

Attached you will find several photos of a recent job using a few of your products. The job went perfectly
and the customer is overwhelmed with satisfaction. The home owners can’t believe how wonderful it turned
out compared to the original floor condition. Your “Efflorescence Cleaner” did
exactly what the info claimed it would and the Rustic Brown "LastiSeal Concrete
Stain & Sealer” is
just gorgeous and gives that stained look without all the hassle of chemical processes.

Here are some pictures of our floors sealed with LastiSeal Concrete Stain canyon
brown. The pictures do not do justice to the way they really look. I am not very good with a camera. You can
see we scored the floors differently, the smaller the room, the smaller the diamonds or squares. My wife used
a spray bottle to apply the stain in several coats, thicker in the score lines, and then used a natural sponge
to achieve the textured look. The floors are extremely
easy to maintain and my wife uses one of those mop things with the throw away pads.
There are several other rooms that I didn't take pictures of. The Woodland Olive in our bedroom turned out really well and we also used the rocky gray color in one of the bedrooms. Our only problem has been plug-in air fresheners spilled in a couple of places and stripped the color off. That is why I ordered today, to re-touch these areas. Otherwise it has been extremely durable.

Our project is almost finished and it looks awesome!! Here are some pictures.
The pool deck is stamped concrete. We started with the Cordova
Tan as a base coat then "faux" sealed, using a
rag, with Rich Earth to give it dimension. The pavers outlining the deck were also sealed with Rich Earth. Once this
was completed, we added 2 coats of an acrylic base sealer from Home Depot. We found that
the "faux" project worked best on a hot deck!!!!
The patio is concrete stamped like wood planks so we used just the Rich Earth to color seal this area to give it a
dark stained wood appearance, applied with a spray bottle and a broom.

Recently applied 2 coats of your LastiSeal Color Stain to my
6-year old concrete driveway primarily to enhance its appearance. Used the Rustic
Brown which closely matches the brick on my house and sidewalk. Can't begin to tell you what an incredibly
positive change it has made in the driveway's look! Wish I had taken some before and after pictures so you
could see the change. Certainly has been worth the money, time and effort in applying this product.
Lloyd H., KY
We had engineered hardwood floors layed over our entire house, except kitchen and bathrooms when we moved into this house 1 year and a half ago. Last summer I noticed some water bubbling through the floors. When my husband started pulling the floor up we saw the floor had molded from underneath. All we know to do at this point is put some kind of sealer down on the concrete. Any advice would be appreciated!
I do know you do need to seal you slab. Don't go with a product from Lowe's - LastiSeal
Masonry & Brick Sealer by RadonSeal is the best concrete/masonary sealer there is PEROID - it
penetrates very deep and closes up all the concrete's capillaries. My parents had a concrete problem and
I did tons of reasearch as to the sealer that would work the best and I found LastiSeal and can't say enough
positive things about it. It can't be found in stores, but there is tons of information about it on radonseal.com
website.

I
make and sell concrete leaf castings. In the past, I used colored concrete powder and paint on my leaves,
but was never satisfied. Since I discovered LastiSeal Color Stain, I have been using it for a year now and
have to let you know how much I love it. I have searched many concrete web sites and stores and have not found
a liquid concrete coloring/sealing product that is as affordable, of such high quality, and so easy and safe
to use. The colors are just wonderful. I absolutely love them!
I use LastiSeal Color to give my concrete cast leaves color and protection. Because of your sealer, I have no misgivings about selling my product. Previously, I used paint for coloring, which did not last. Your concrete sealer lasts and looks beautiful on my leaves. I am enclosing some pictures for you. Thank you for a wonderful product!

I had hairline crack in basement wall. It is poured concrete. I coated
the outside wall with LastiSeal
Brick & Masonry Sealer and haven't had any leakage since.

Sealing outdoor concrete
Last winter we had some heavier than normal ice storms and my concrete driveway paid the price. There were divots almost everywhere. One section was particularly bad with two large areas (2 to 3 feet in diameter) in which the top 1/2 inch or so of the concrete had crumbled away. This process had also started a crack.
Radonseal completely solved the problem - no further erosion, chipping, flaking, etc has taken place since applying Radonseal - - NONE! So, I am sold on the strengthening properties of RS and that is mostly why I want to put it in my new building.
Gary C., PA
Last year I bought some of your RadonSeal and applied it to my concrete garage floor and driveway. The garage floor is at least 50 years old and I put the driveway in about 20 years ago. I had a 4 foot by 6 foot area in the garage that was flaking and basically turning to powder. The driveway showed signs of minor erosion in different spots. Well, I finally had a chance to clean out my garage this spring and noticed that the floor didn't have any more flaking or peeling like before. It was solid and showed no sign of any more deterioration and there is no further damage to the driveway.
Thanks for the great product.
Rick G., PA
Applied RadonSeal on new driveway. Went on easy, dried without streaking (which
was a problem my neighbor had with a sealer he used), clean-up was easy, and most importantly, the driveway looks
great! I liked the fact that this strengthens and extends the life of the concrete and that it is a
permanent bond! I plan to order the DryWay sealer to further protect the surface
from oil spills and road salts. Thanks for a great product!
Donna K., IL
Ice melt costs us $1,000.00 per pallet (40 boxes @$25.00). We easily saved $4,000.00 this year – DryWay
sealer paid for itself in the first year (not including the savings in
labor)!
We used a quarter of our normal amount of ice melt to treat our “bad spots” - concrete
stairways and sidewalks through our campus that are shaded during the winter months (no melting assistance
from the sun). Those areas were always the worst to clear and, by far, required the most ice melt and were
the most labor intensive to handle. As they are our main walkways, they require our complete attention to
cut down on the slip hazards for our students and faculty.
Because of the DryWay, we were able to breeze through them and suddenly had “extra” time to focus
on our parking areas. We were actually able to use our riding 6’ sweeper (attachment for one of our
mowing units) to clear our walkways this year.
The snow and ice didn’t bind to the concrete as in years past. We merely hit it
with a light dose of ice melt and our work was done. It’s a good thing, because the snow/ice accumulations packed
tight on the parking areas and we had all we could do to get those areas ready for pedestrians. ...

DryWay prevents chewing gum from bonding to concrete and cleanup of those black, cancerous
spots is a much simpler process. The gum lifts right off with very little residue left
behind.
Before the sealer, we could only chip away tiny fragments at a time and there was always a significant (unsightly)
amount that we’d have to leave in the pores because we just couldn’t justify spending that much time per
gum wad.
Now it’s just a matter of spending about 10 seconds or so per piece to clean each spot and move on.
It’s certainly not 100%, but the manpower savings are significant and it’s turned a dreaded chore into
a much more productive operation.

Sealing bricks and stones
I thought I would let you know that I covered half my house with the LastiSeal
Satin sealer. It took about 7 gallons
to do so. It was TOO windy to finish it Sunday. It actually changed my original red and black brick
BACK to its original color. I did not realize it had turned to "orange and black". My wife
had been calling it the "Emperor's
New Clothes" as she did NOT think it was worth the cost. She said that she is now impressed! Thus, I
hope to use the remaining 3 gallons on the back side of the house. I know that I will be buying another 5
gallons to finish the house completely but I can't afford it until May. I used a hand pump sprayer. It worked
better than I thought. My neighbor even came over to ask my why my house looks so much different. Just thought
I would give you an update. Thanks for your advice. I know it will seal for years but getting
my original brick color back was SWEEEEEEET! Enjoy,
Weldon, Abilene TX
I recently purchased Lastiseal Masonry sealer in the satin finish to seal our indoor
stone floor. After the 1st
application the floor appeared cloudy in spots. We decide to apply a second coat to see if this would fix the problem,
and it did. The floor came out BEAUTIFUL, we couldn't be happier with the results. The Lastiseal brought out the
natural colors of the stone as if it were wet, bonded the entire floor together and made it stronger than ever.
Once
the weather warms up, we also plan on using Lastiseal on our stone chimney. We hope
that by sealing the chimney will help eliminate our leaking issues. I can't wait to see the results.
Thank you
again for such a great product and for the friendly and helpful staff at RadonSeal!
Sincerely,
Stephanie, PA
Hi, I just wanted to let you know how much I like your product, Lastiseal Masonry & Brick
Sealer. I use it for the final sealer on my concrete sculptures. The
best product I have found. This is my web site: www.buygardenart.com

Repairing cracks in concrete walls and floors
Dear Radonseal,
I am writing to share the amazing results from using your products. Last year I injected several cracks in my foundation, as well as a leaking pipe perforation. My basement has been completely dry, and I'm still pleasantly surprised and I can hardly believe these products work as well as promised.
Because of that positive experience, I decided to tackle my high radon problem. I applied Radonseal concrete sealer to my basement floor and walls. I waited awhile and then did a radon test. Just as expected, it reduced my radon levels below the limit.
I am a very satisfied customer, and I thank you for all the assistance you have given me as I nervously tackled these projects.
Bob B., MO
I have to tell you what an incredible product you have in your Concrete Crack Injection Kit! It is the absolute best thing on the market for repairing leaking cracks in poured foundations. I recently purchased the kit to repair a crack I had in my basement, making it unusable due to water seepage at the slightest bit of rain. The kit not only gives you everything you need to complete the job (something unheard of nowadays!) but was thoroughly explained in the accompanying DVD. No kidding, I'm very confident my 12-year old son could've performed this repair the DVD was so thorough!
I've had problems with this crack for several years and with one on the other side of the basement I did the old "back cutting and fill with hydraulic cement" repair only to find water again seeping through only 6 months later. What a mess cutting cement makes! So I searched the net looking for alternatives and yours seemed to be the answer. It was inexpensive, easy, didn't make a mess of my basement, and lo and behold we've had two torrential rain storms within three weeks and NOT A DROP of water!!!!! BONE DRY!!!! And the cost is really not that bad when you consider what a dry basement is worth to you!
I am truly impressed and will tell everyone I know about your products. Your product works, plain and simple, a concept that is harder to find these days!
Al D., Western NY
You definitely have a wonderful product. I used one crack injection kit at first to see how well the product really does work on poured cement wall cracks (hairline vertical) to stop water leaking into my finished cellar. This is by far the best DO IT YOURSELF I've ever came across. Without hesitation I ordered my second kit for one more crack. This product works Fantastic!!!! No digging outside, but penetrated all the way through to the outside. Instructions were plain and simple and if needed, there is phone support to help with all questions. Contractors quoted me $650.00 a piece to fix them but with your product both cracks were fixed for much less than one by a contractor.
Thanks Radon Seal,
Ray B., NY
I don’t normally write testimonials, but I had such amazing results with this product that I felt compelled to share my experience. I had drains installed in my basement this year which I hoped would resolve all my water issues. Much to my surprise, I still had water through tiny cracks in my poured concrete foundation. I got three estimates to fix the crack. The lowest estimate was $600 per crack. Doing my research I came across your company. After speaking with a representative, I ordered my DIY crack repair kit. The instructions and application was so easy. I repaired the cracks 1 day before Hurricane Irene hit. I was so happy to see that no water came into my basement from the cracks I repaired. Unfortunately, other cracks which were not an issue before Irene, leaked.
I quickly ordered 3 more repair kits and have had no problems with water in my basement since. I have told all my family, friends and neighbors about this product. It is so nice to find a product that is simple to use and works exactly as it claims. I am a customer for life. Thanks for providing a great product and excellent customer service support.
Lydia H., CT
I purchased you DIY kit for a 6ft crack on my basement wall which would leak when we have a heavy rain. I was quoted $600.00 by 3 companies to have the crack fixed and paid $148.00 with shipping from Radon Seal. First and the most important, a first grader can use this product. It took me 20 minutes to clean the crack and remove all the paint from the wall, 20 minutes to attach the injector cups and epoxy the wall. After 2 1/2 hours, I started injecting the sealant which took about 20 minutes. That was it, simple, fast and yesterday no leak with the snow melt. I will be buying another kit to fix one more crack on my wall. I will let everyone I know about Radon Seal. Thanks for a great product.
Mike K., NY
P.S. This is my second crack that I did. After doing the first crack last week, I think a 2-year old could do this. My first crack has already worked after completion, (we had a thaw) and no leak. Doing the second job, I could have done it blind folded. This is so simple and saved me over $1200.00 for both cracks. I will be back this spring to buy your cleaner and concrete sealer. Thanks again for the fast shipping and response. Your a class act company.
I was in the process of remodeling our basement when I discovered black mold behind drywall that covered the outer-wall foundation. Upon further demo, I discovered 2 vertical cracks in the foundation wall allowing water to seep in.
I called a well-known local basement sealer company and was quoted $650 to seal one crack. I ordered your epoxy crack repair kit for $190 and sealed the first crack myself in about 4 hours. It worked just as described in the easy-to-follow instructions. Your product really sells itself and I'll be ordering a 2nd kit to seal the other crack.
Many thanks for making our basement dry & mold-free, my children can now play down there without going into an asthmatic attack. Thanks again for a superior product,
John, Woodridge, IL
Dear RadonSeal,
After extensive research, I have decided to order the RadonSeal DIY injection kit form
your company to fix a diagonal crack in my basement. On rainy days, water would seek through the crack leaving a huge
puddle on the floor.
I have now fixed the crack and the basement has been completely dry ever since. Attaching a picture. Thanks,
Ole A., CT
This is my third time ordering the D-I-Y Concrete Crack Sealer from Radon Seal to fix severely leaking basement walls. I tried it the first time on my worst leaking crack to see how it would work. It was easy and it worked great. After a year, I did my next wall and waited a while before finishing my basement. I've had no problems at all since fixing my first crack in 2006. I highly recommend it... The professional crack sealers wanted $550 per crack!.
Thanks Radon Seal,
Festus A., MA
We have used your product, D-I-Y foundation crack repair kit. What a wonderful product and great service! We had some questions and called the toll free number twice for extra information, the answers were very helpful and the crack is fixed completely. Thank you for all the help. We priced having this crack fixed professionally, the lowest bid was $500! We did it ourselves and saved over $300! We were worried about the odors from the product, they were minimal, and it was easy to use. Thank you for such a great product.
Thanks Radon Seal,
John F., CO
I just finished a repair on my poured concrete foundation…What a product…work great..just like
the CD said it would… It was worth the money… The urethane went right up
the crack to the window..sealed
everything… Have a 10 inch foundation and it oozed though the inside to the outside.. The secret is
in the slowness of the application…or
the slow squeezing of the caulk gun…
Thanks!
Dan R., NH
I have been living with water infiltration from leaking foundation wall cracks for 20 years. Once I found the RadonSeal website and discovered I could repair these cracks myself, I jumped at the opportunity. I have repaired five cracks, and have three more to go. The attached photo is one of the two repaired cracks in my crawl space. After I repaired these cracks, I covered the crawlspace floor with a concrete slab, and I can now use this space for storage!
You have a great, easy to use system. I only wish I repaired these cracks years ago!! Thanks for everything!
Dan
I am writing to say how pleased we are with the crack repair kit. The product installed exactly as shown in the DVD included with the kit. Our homeowner is thrilled that the foundation crack no longer leaks, despite the heavy rains and flooding we have had here in the midwest. And when the homeowner is happy, everyone is happy! You shipped the kit in record time as well, we will definitely order from RadonSeal again if the need arises.
Varl H., WI
I had a hairline, vertical crack in my poured concrete basement wall that leaked into the basement after some snow that piled up near the house melted. I purchased your low pressure polyurethane injection system. Everything that was needed came in the kit and the repair went exactly as described in your instructional video. The polyurethane foam expanded, filling the crack clear through to the opposite side of the wall and through parts of a temporary cement patch. So, I’m positive that the crack is now filled and sealed, and I have not had any water problems since the repair. I highly recommend RadonSeal’s polyurethane injection system!
Charles F., WI
In a day when people have to be on guard over rip offs or companies "overhyping" products, I must say yours worked flawlessly. A company wanted $720.00 to fill a crack in my foundation wall, needless to say I did for a lot less using your products. All one needs is patience. You were money well spent!
Philip, Derry, NH
Cheryl, I had the chance to use my DIY crack injection kit this weekend and it worked great. I had my doubts
that it could be as easy as the video but I was pleased to find out that it really was that easy. No problems
at all. Great product! Thanks.

I purchased and used your low pressure crack injection kit in my home. After last weekend, with melting snow and rain falling, I had no more leaks. Thank you for a product that does what it supposed to do. I have ordered another kit for my nephew. I am certain he will be as pleased as I am, with your product. Again, thank you.
Your CD is great and your product definitely is worth the price. The kit was complete and made the task very easy, even for me!
Gordon R., IL
Well, it's been a while since I installed the RadonSeal in the crack in my cellar, which ran from the cellar window to the floor. I wanted to wait a while to make sure it sealed with heavy rains. Every time it rained, I would get water in my cellar but now it is completely DRY. This stuff is GREAT! The only mistake I made was to not remove the epoxy seal that was over the crack. That stuff hardens like a rock – now I have to chisel it off if I want to remove it. But I don't care if it's on there as long as the cellar stays dry. Thank you so much for such a great product!
Del B., MA
I had a thin vertical crack in my poured concrete basement walls and every time it rained I would get water seeping in through this hole. I initially thought about using hydraulic cement to fix this leak because I would soon be finishing my basement but after reading about all of the products out there I decided to go with the crack injection system by radon seal. It is not the cheapest way to go but I am now convinced it was the smartest way to spend my money! Everything that I needed arrived in a box neatly arranged. It was very simple to follow the directions provided and even included a CD-ROM with a video for directions. A week later we had a huge round of downpours and thunderstorms and I was so pleasantly surprised to find that everything in my basement was dry this time thanks to this product! A few months later we started finishing off our new dry basement and haven't looked back since!
Matthew L., IN
Just finished repairing a crack in my basement wall using your D-I-Y Concrete Crack Injection Kits and am quite impressed with the results. The “how to do it” information provided in the kit was easy to understand and the product application was straightforward as depicted in the video. I have included a few pictures of the repairs. Outstanding product and a perfect solution to a leaky crack in our basement. The process worked well and I had only one mishap, the caulking gun slipped out of my hand and broke off the injection port. I just held the port back over the crack until the liquid started coming out of the next higher port. A little messy but worked anyway ... just as your video said. Thanks again for such a good product.
Tim O., OR
Many thanks for the ultra fast shipment of the concrete crack repair kit ordered the other day and received yesterday. Also one several months ago.
The instructions are really great. Almost anyone can do the repairs themselves. A few months ago I used the first kit and this was the first time I even tried to repair my own basement leaks. Many thanks.
John L.P., IL
Thank you for your great product! It has saved me hundreds of dollars in repairs. The Radon Seal sealed the stress cracks that were previously leaking water. I will most definitely be purchasing more seal in the future. Thanks again.
Greg G., GA
Thank you so much for a great product!!!! I have used both the Radon Seal, upon completion of my basement and later the poly crack injection kit, to address a leak on the corner of a 14" foundation wall (due to a horrible concrete pour). I had actually gone through all the headaches and steps you describe on your site, during my plight of wrestling with the leaking foundation wall. It was an exact description of what I was dealing with. The injection kit worked like a charm, two years now and NO MORE LEAKING. I am actually doing the other side of the house now, as a preventative measure. Thank you again.
Scott K., PA
I received your crack injection kit at my home during the week and performed the
application over this past weekend. As advertised, the application went off
without a hitch. The installation instructions were put together well and I
was very pleased to have the added information available with the included
computer CD. Opening the crack-injection kit was almost like unwrapping a present: the
kit itself was packaged very well. All the items that I needed to complete
the job were included in the kit. I was especially taken by the innovative,
convoluted mixing nozzle. What a great way to ensure the 2-part contents of
the foam cartridge was mixed!
Daniel L., CT
I have just repaired two large cracks in my garage walls with your Easy-Peel Crack Injection Kit. Thank you for a great product, quality materials, extensive package contents and superior customer service!
I will definitely let everyone know who to go to for injection repair.
Chip M., NH
Just spent the day injecting a worrisome crack in my sub-floor with your crack injection kit – it worked flawlessly, just as advertised. The foam continued to expand and bubble out of numerous pinholes all along the crack over a period of many hours, an indication that the crack has filled completely with foam, which obviously means that it won’t be an available passage for moisture! The directions were easy to follow, and the process was surprisingly quick. Provided that the floor no longer leeched moisture, I am and will be a very happy customer; all other options were very expensive.
Jay W., CA
I just wanted to let you know how pleased I am with your product Easy Peel Crack Injection Kit. I repaired a crack in my basement wall and it is working excellent. The instructions were clear and easy to follow!
Darrell N., MI
I had a problem with a crack in my basement wall stretching from the window to the floor. It was a small crack approximately seven feet long and leaked water from the outside of the house into the basement. I ended up with some black mold on the wall studs, wall board, and floor.
I ordered the DIY crack injection kit and received it in two days . I watched the video twice and followed the directions step by step. Your directions are very clear and very doable, even for an amateur. The materials acted exactly as described. The sealer penetrated the entire crack through the wall to the outside of the basement. I am confident from what I see at the top of the crack that it penetrated the entire crack as you advertised. It has been about three weeks since I completed the repair and my basement remains dry. I am a very happy customer and would recommend your products and procedures to anyone having a similar problem.
Thanks very much for your support and your products,
Jeffrey A., MO
Just want to say thank you for the DIY Crack Injection Kit. I have used it on 2 cracks in my foundation which used to pour in water. Well we just got through with one of the largest rainstorm in over 100 years and both cracks
where I used your product were bone dry!
Anyone who ever goes to HD or Lowes and buys the hydraulic cement is wasting time and money. I'll be sure to pass your website around to everyone I know
who basement walls leaked this past Nor'Easter.
John C., CT
Last year we started having trouble. Every time it rained, we ended up with a very large puddle of water in our basement bathroom. We took down the wall and found a large crack that ran from the top to the bottom of the foundation. We found your site online and purchased a D-I-Y Crack Repair Kits - Epoxy Injection kit. With the help of your easy instructions, my husband fixed the crack.We have had our share of heavy rain here in New England this summer and no leaks. We decided to buy two more kits for some smaller cracks we have to repair. Thank you!
Rebecca J, MA
I just wanted to tell you how happy I am with both your product and service. I purchased the Do-it-Yourself Foundation Crack Repair Kit (2 of them actually) and found it to be easy to use and the video instruction very useful. I would highly recommend your product to anyone considering a basement foundation repair. I am a first-timer doing anything like this so I was a bit intimidated at first, but I took my time, and the results were great. Your response time to my placing my order was excellent and I can't tell you how much work this product has saved me. Thank you again for your help!
Darcy Q., Manitoba
I used your crack injection kit this weekend to seal a few cracks in my basement and found all the materials and information very useful, straightforward, and complete. Everything went very smoothly thanks to the comprehensiveness of the kit. You guys put together a great product. Hopefully it will do the trick and keep my basement dry.
Scott D., PA
Hi, my name is Ron,
Last year, I ordered one of your foundation crack repair kits to try on one of the four cracks I have in my foundation. I have just checked outside and inside to see if it is still in good shape and I am happy to say it is in the same shape as when I got done doing it and I have not had a drop of water since I fixed it. Thank you for a having such a good product! I'm going to be ordering soon to fix the other three cracks.
Ron F., WI
Your PipeTite Injection Kit has successfully fixed the leak around a pipe through my basement wall. It has been leaking for several years. Caulk and hydraulic cement did not work but PipeTite has held over two years now. Thanks!
Charles M., NY
Thanks very much for your DIY Crack Kit. I was very impressed with the clarity and detail of the instructions! It was as easy to use as described and I would definitely recommend it to anyone I talk to.
Paul A., Calgary, Alberta
I wanted to let you know I have come back to you for a 2nd order of the foundation crack repair kit due to the fact that the first one I ordered from you worked great! Everything you said about how well this product works including easy installation was absolutely true. Thanks for bringing this product to Homeowners.
Donna M.N., MA
I just finished using your crack injection kit and am very pleased with the results. I had a new home built in 2007 with a full basement. There was a vertical crack under a corner of my basement window and it let moisture into the basement.
I viewed your video online and it made perfect sense to
be able to repair these cracks from the inside rather than try to seal them from the outside by digging under the window well and somehow re-applying
sealer to the foundation.
I found your instructions simple to follow and had no surprises when I put on the ports, applied the epoxy sealer and finally, applied water and injected the
polyurethane into the crack. I know the foam penetrated, because the window well had a part of the foundation exposed and the foam expanded clear to the outside!
David S., Utah
Your “Do It Yourself Crack Injection Kit” worked very well. So well, in fact, that I plan to ad it as a service to my future customers. Not only does it work but you instruction guide and how to video were clear and easy to follow. I look forward to a continued business relationship with RadonSeal.
Vernon "Skip" Barnes, MD
I just repaired two cracks in our poured concrete foundation using your Do-It-Yourself Crack Injection Kit. What a GREAT product! It was much easier to use than I anticipated and having done the work, I know it was done right so I'm not second guessing the repair. It was a painless project. :-)
Mark G., OH
Your Elasti Epoxy Crack Filler Kit worked perfectly. The crack in my garage
floor was quite large, but dormant. Average width about 0.5" up to 1" wide.
I'm very happy with your ElastiPoxy Crack Filler. Using a grinder with masonry
wheel, I leveled the edges of the crack so they were in the same plane. Removed dust and debris with air
compressor and shop vacuum. Filled the crack with sand to within about 2 inches of surface. Sealed sand with
a layer of concrete caulk and let dry to prevent epoxy from seeping into sand.
I expected to do multiple pours of epoxy to fill the crack but just two pours were needed. I sliced away excess epoxy with single edge razor blade held securely in small vise grip pliers.
Remaining low spots and bubbles were filled using a paint brush dipped in epoxy. This technique worked nicely. Once set completely, I used a 36 grit grinding disc in my Baby Makita to level and match the epoxy with crack edges. This worked perfectly. Grinding discs lasted for 6' to 8' of crack length. Note that cured epoxy did not clog the grinding disc.
Filled about 20 feet of small crack, too. Average width about 3/16" plus or minus 1/8". For me, the easiest way to get epoxy to crack was with a 2" wide plastic putty knife. Dipped the knife in epoxy and let it drain from the edge (held vertically) into the crack. Then, I sprinkled masonry sand onto epoxy to keep it from draining away. Once set, I returned to fill gaps. When completely cured, I used the same grinding technique to finish the crack.
Results are very satisfactory and pleasing. Your product is the best!

I'm very happy with your ElastiPoxy Crack Filler and Radon
Seal. For years I've been trying to solve a leaking concrete roof problem
by buying stuff from Home Depot, and finally I got something that does the job correctly.
Glen J., NJ
I would like to take the time to thank you very much for an excellent product for repairing cracks
in my basement block walls. My basement walls started getting cracks after a few years. I used many
supposedly miracle products to fix the cracks and none worked. All I ever ended up with is a mess and the
cracks always coming back. I purchased your epoxy crack filler kit and followed the instructions that your
friendly sales staff gave me for applying the crack filler and it has worked perfect. I have not had so much
as a hairline crack since applying your product several years ago. Thanks again!
Brent H, Illinois
I am totally satisfied with RadonSeal’s Elastic Epoxy Crack Filler Kit.
I appreciate your service and rapid delivery. The included application guidelines provided all necessary information
needed to develop individual application techniques for repairing gouges, spalls, chipped
edges, control joints, and cracks in a swimming pool deck. Quality of repairs made with Epoxy Crack
Filler is excellent!
Play sand, which is available in many colors, could be mixed with Epoxy Crack Filler to closely match the
color of my “PolyPave” finish. Small batches with a 2:1 ratio of sand to Epoxy Crack Filler were
conducted to test the results.
A hairline to 1/8” wide crack was a great concern. I mixed only enough Crack Filler at a time to halfway
fill a squeeze bottle (mustard). By repeated passes, I filled the entire length of the crack to within ½ inch
of the surface. The repair was completed with a 1:1 ratio of sand to Epoxy Crack Filler Mix and followed by
sprinkling it with sand. See detailed feedback with photos in PDF.
William C S., IN
I used your CrackWeld 4-pack to fill many hairline cracks and several 1/4 inch cracks on my driveway and garage. I read your instruction sheet several times and watched the on line video. Once I did a couple areas, I got better at it. I bought a 50 lb bag of Silica Sand from Menards. It was only $4.00 and it sure came in handy. I had about a total 150 feet of cracks and having the extra sand made it much easier. Also, instead of getting down on my knees and scraping with a putty knife and sand paper, I used my ice scrapper that I use in the winter time to scrape ice from my porch and sidewalk. The ice scraper has a long pole on it like a shovel and I was able to scrape down the lines very easy with it. I did get down on some areas and hit it with sand paper but not really much. My driveway and garage are over 30 years old and some of my neighbors, in the last few years had spent thousands of dollars to have their driveway repaired because of cracks. I am glad I found your product and was able to use it effectively while my cracks were still pretty small. I was able to do all this with your product all by myself. I will be buying more CrackWeld to do some hairline cracks in my basement too.

BioZap for mold stains and musty odors
I have used BioZap Air Purifier for one year and have just ordered a second jar. Our house was built on property that has a high water table, therefore we could only have a crawl space. The crawl space has been our nightmare for 13 years until my sister ordered the BioZap Air Purifier and told us to try it in the crawl space. We tried many products to get the musty odor out of our house. We had the crawl space sprayed with deodorizer products, we have several vents to circulate air, and also put a fan in one of the vents to keep the air circulating. Nothing we tried worked.
The moment my husband put the BioZap Air Purifier in our crawl space the odor dissipated. The next day I walked into the house by the entrance to the crawl space, the odor was gone. Our house had a pleasant aromatic scent, not overbearing, just subtle. We have our second jar of BioZap in the crawl space after one year of use with the first jar. This is an inexpensive way to keep the musty odor out of our home one year at a time.
Gary and Melinda R., MI
I have tried everything to rid my home of the musty, moldy smell in the basement. We tried ozone machines, de-humidifiers (really expensive ones), and tore the drywall off to find fuzzy studs. We also replaced the carpet with hardwood and still the smell.
There isn't a water leak, just moisture wicking through the concrete. I know about tea tree oil being a natural fungicide so when I found your product it was a happy day. BioZap works like a miracle!
My 19-yr old daughter is sensitive to mold (nosebleeds, headaches, nausea) and she's the one who could tell how clean the air is when we use your Bio Zap. She became ill again, that's how I know it was time to order a new supply. Its always a battle. Thanks for your great product! I would be happy to be a reference for you on the West Coast. We have lots of mold and mildew here!
Dana Heiser, WA
To the creators of Biozap,
4 years ago we used your product on our concrete floor in the basement. Our
daughter had been on asthma meds for a few years and would cough during the
night. After spraying the product she never coughed again through the night and
we quit giving her the meds. Also, our house is over 110 years old and had
water issues for years. For the past 4 years we have never had a problem with a mold or mildew smell. Thanks so much for Biozap.
The only thing I would tell customers is the product does have a
strong smell for the first few hours, but within 24 hours there was no longer an odor of
Biozap or mildew. Our house smelled clean and fresh.
Renae S., ND
BioZap is a great natural product to get rid of moldy smell! I had a real bad mold problem this past summer when severe mold odor come out of all of the cold air return vents as well as heat registers of my house, upstairs as well as downstairs. This caused us to have severe respiratory problems. My nose ran almost non stop as long as I was in the house. I searched everywhere for a simple product to combat mold in the duct system. None of them seemed right, until finally I found BioZap. Its description seem to be too good to be true. But I bought one big jar of BioZap for around $50 to just give it a try.
I placed the jar without its cover in my downstair cold air return duct. Its smell came out of my upstair heat register a few hours later. I closed or sealed off all cold air return vents and heat registers for the next three days. Then I got curious, so I opened one heat register cover. To my surprise, I could not smell a thing. Then I opened more and more and found only faint smell of tea tree oil from some, otherwise nothing. Later I found out to get rid of moldy smell in small space that is hard to place the whole jar in, a few spoonfuls of BioZap smeared onto its inside wall would do the job also.
Richard T., VA
I have tried many products (bioworld,odoban,nokout) for my musty odor problem and nothing was working.I then tried BioZap and noticed a difference right away. As an added benefit the tea tree oil doesn't bother my allergies like most synthetic products.
Doug N., FL
I live in the New Orleans area and my home was a victim of Hurricane Katrina. Three large trees fell onto my home, and the large holes allowed much rain to get into my attic and flood the floor of my home.
I was happy to be one of the fortunate people who was able to have my home repaired within six months, but not happy with the lingering moldy smell. I tried many products, some "professional," but could not rid my home of the moldy odor.
I discovered BioZap on line, and thought I would give it a try. Boy, was I glad I did !!! Within a couple of weeks, I could tell that it was working. Within a short time after that, there was no more odor, as BioZap had done the job.
Thank you for a product that lives up to its description.
Claire C., New Orleans, LA
I just had to share my thoughts on the Biozap product. I have been using it for over a year now and it is GREAT! I am a school teacher being exposed to germs and odors can be sickly– so I use some Biozap in my classroom. I keep it in a safe place, stirring it weekly, and it does a wonderful job. My husband and I use it at home, and when we run the heater/AC, it really helps with the musty/moldy smells. I would recommend this product to others. I plan to continue purchasing the product every time I run low, I place the call for more .... thanks!
Carol H., VA
We first heard of your BioZap product in 2005. Since I have a host of breathing problems, we decided to try your
air purifier in our air
conditioning vents (we chose the lemon scented). What a difference!! The mustiness is gone, and stays
gone for the entire season! Nothing will make my emphysema go away but using BioZap
does make it easier to breathe in my house...for everyone. We can't thank you enough.
Linda B., MY
I highly recommend BioZap Air Purifier as a very efficient and effective way to CLEAN your air; it doesn’t’ just mask the musty order, but actually seems to disable the mold spores. I know because I’m a stay-at-home mom who is allergic to what I call "everyday molds", that slight musty order that is prevalent in many of our older buildings, basements, and closets. BioZap cleans the air out in minutes, and I can breathe easier. I even pack a small amount to take with me to hotels, cottages, wherever I may be uncertain of the air quality.
Sherry M., VA
Thank you for such good service and a wonderful product. I have a crawl space under my Great room that was always smelling of dampness. Since I first purchased your product, BioZap Air Purifier, in May of 2006, I have not had any damp smell. It is a small miracle.
Jane H., NY
BioZap is terrific! I live in Florida, known for mold. I had one extremely moldy screened-in porch. The house had been empty for more than a year and the roof had leaked. It was rank! I used Biozap and now it's as sweet as can be. I was amazed! I also used some in my duct work and it worked like a charm. It is so nice to have a mold-free home when I return.
Dana T., FL
Your BioZap products have given a new and clean sparkle and scent to my condo, my clothes, my car, and everything else I own. Tea tree oil is nature's answer
to the assault by mold, mildew, viruses, bacteria, and roaches that constantly invade life in Florida. Your products present a practical way of infusing protective tea tree oil into every aspect of living in paradise. I tell all my friends and family about the benefits and the convenience of incorporating the RadonSeal products into their own homes.
Len H., Pompano Beach, Florida
I purchased 3 pails of your RadonSeal Standard and some BioZap. We had low levels of radon detected and there was also a musty smell that I wanted to get rid of before finishing the basement for a bedroom and family room. I found the RadonSeal to be an excellent product to work with and used with the BioZap, it completely eliminated all of the musty odors. Your staff were also very helpful in deciding which products would help resolve these problems. I would recommend your products to anyone.
Thank you!
Scott M., Piedmont, MO
BioZap Air Purifier & Deodorizer does work! I want to tell you. I live in Michigan on a lake and have a crawl space. I been using the BioZap Air Purifier & Deodorizer for 4 years now. I keep one under the house in the winter time after I close my outside vents and I put some in my return side on my heating and air condition. I don't have the moldy smell when I bought this place. I believe that this BioZap Air Purifier & Deodorizer does a beautiful job of keeping air fresh in my house and I don't have a spider problem in my house like my neighbors do. This is a great product!
Dave F., MI
Amazon reviews: I live in a high humidity coastal area where things can get musty smelling quite quickly. A jar
of biozap will make musty smokey drapes and carpets smell fresh within hours of opening. The tea tree fragrance
is quite pleasant, not overwhelming. Great for a closed camper or vacation cabin that has not been occupied for
a while. Have been using this product for years and would recommend it.
E. Bailey, NJ
Thanks for your BioZap Mold Cleaner! After years of searching, I have finally found a product to remove unsightly mold from the walls in my car wash. It not only cleans the molds, but also prevents their return for two or three months even though the walls are almost constantly sprayed with water.
Fred B., TN
I just wanted to thank you for your wonderful BioZap products. We had two major storms here in the Northeast within
a two week time period that dumped over 9 inches of water. Our french drains just couldn't keep up and our
basement got an inch of standing water. We've used BioZap Cleaner with great results
in cleaning the areas that got moldy. Not only that, they smell wonderful! I've just placed another order
because I love the scent, and how well it cleans.
Theresa D, Long Island NY
Sirs, I received your BioZap Mold Cleaner right on time as promised and it is doing a great job on eliminating mold on leather. I collect antique gun holsters and until now, could not find the right product that would remove the mold. Thanks,
Jerry B., CO
I just wanted to tell you how happy I am with the BioZap Air Purifier product. This is our second year using it. During the hot summer months, our basement always has a moldy mildew smell to it, not to mention the mold that is on anything it possibly can, including leather boots and shoes stored down there. Just one of the 16-oz. jars took care of the mold and mildew smell in our basement for the summer and there was no mold on the shoes and boots. I would highly recommend this product to any, especially those who have allergies and asthma like some of my family members. Thank you again!
Michelle S., NJ
Several months ago, I helped rescue two sick and starving kittens. It turns out they had ringworm (which is fungal), but not just any ringworm – a very aggressive strain. Unfortunately, it spread to my other kitties. I was so distraught for a while, wondering how I would ever control it and get my kitties well. I am happy to say that they seem to be on the road to recovery, and I know it is due in part to your excellent products. Not only have I used the BioZap air cleaners, but also your all-natural BioZap Mold Cleaner. Mold and Fungi are so difficult to combat, because you can't see them, and they could be hiding anywhere. I know it has made a difference in my case to have a product that helps to clean the fungi from the air.
Thank You for developing a product that I'm sure has been helpful to many people.
Lisa A., Texas
I put the Bio-Zap near the intake of the air handler on my tug boat. The musty smell was gone in a few days. I am a believer! Thanks,
Peter B., VA
This summer we had a very bad rain and wind storm. It has flooded my basement with over 12 inches of water. After it was pumped out, it left behind a very strong musty odor. I tried using a large fan to blow the smell out of the window, but it did not work. Then, I purchased several containers of BioZap Purifier and after 1 to 2 weeks the terrible odor was completely gone. I thought you would like to know.
Earl F., IL
I have to admit I was a bit skeptical about your BioZap Air Purifier. I bought it for my parents basement. Their home is 40 years old and the musty smell was really unbearable. After three days of having one BioZap tub set up in the basement and one in the fan area of the furnace, the smell is almost unnoticeable. I have placed an order for the spray cleaner to clean up the mold that is growing in the corners and I hope that will completely take care of the odor. Thank you!
Donalda P., IL
I have also used BioZap to eliminate the musty odor in my basement. What a great
product! I used the Cleaner to get the bulk of the items that had mildew growing on them. Then I placed the
Deodorizer throughout the basement to completely freshen up the basement. This is a natural
deodorizer that does an awesome job on killing mold and mildew.
I've been using your products for years and trust nothing else. I tell everyone who asks what I used to fix
my radon and mold problem to visit radonseal.com.
Kevin C., OH
I had a leak under my sink about two months ago that left a musty smell in the cabinet which was very noticeable when you opened the cabinet door. The plumber had told me to keep the door open as much as possible and to place a small fan where it could
blow in fresh air to try to get rid of the musty smell. This was taking forever. I don't know how I came upon your product on the internet but I am so glad I did. After reading about your product I decided I would give it a try.
I put some of the BioZap air purifier in a small container and placed it in the cabinet. I was amazed when I started to prepare my evening meal and opened the cabinet to get my cookware and there was a big improvement. The musty smell was almost gone. I will order more of your product because your claim is genuine and I want my entire home top smell this fresh and clean.
Gloria C., PA

Backup sump pumps
The RH-1400 battery pump arrived and we have already installed it! Very easy to do, as promised! I love the security of not having to worry about a power failure again and not having my main pump be able to do its job!
Paula C., RI 
Installed the RH-1400 day before yesterday. Followed your excellent directions. Job took a couple hours but went well. Pump has been tested and works well as advertised. When it rains, my main sump pump gets a workout. I have been concerned about power outs and main pump failure. But now I have peace of mind.
RadonSeal has been a delight to work with and very professional. Thank you.
James A., VA
Installed the battery back up sump pump RH-1400 today. Had no problem with the installation of the unit. Working fine. It was nice to receive a package that was complete with all parts need and good instructions, easy to follow. Was a pleasure doing business with you.
Robert P., NY
My buddy and I installed the battery backup sump pump RH-1400 yesterday. We were both impressed with the unit and the fact that everything we needed came with the kit. What a smooth installation!
Although a little more expensive than Home Depot models, this is such a more advanced system with many advantages. Glad to have the piece of mind that comes with the RH-1400!
Glen G., MD
Thanks much for your personal assistance and professional advice when I ordered your RH-1400 Battery Backup Sump Pump. Before calling you, I conducted extensive research on back-up sump pumps, reviewing dozens of your competitor’s pumps. The RH-1400 is the best on the market … period. I’ve risked a flooded basement for years by not having a back-up system. Not only is your pump the most reliable, it’s the easiest to install for mechanically-challenged do-it-yourselfers like me. Two bonuses with your system, that no other systems have: I don’t have to worry about filling the battery with special fluids each month (like the other second-rate back-up battery systems) or worry about the pump clogging or corroding from years of sitting in a muddy sump pit (how ingenious, the pump sits on dry concrete outside the sump!). I can assure anyone looking for peace of mind and reliability, this is the one. Thanks!
Bob G. - Barrington, IL
I
purchased the RH-1400 but used a plumber since I wanted to upgrade both a primary and battery back-up
pump. It took about 1 ½ hrs. to
complete the install. He tested both the primary and back up pump through a few on-off cycles with
both working fine.
I did considerable internet research on battery back up pumps before deciding on the
RH -1400. In all honestly, I hope to never have a need for the back up pump but now I have greater “piece
of mind”.
Thanks again, Radon-Seal.
Eddie W., TN
Just wanted to comment on the speedy delivery of the Battery Backup Sump Pump RH-1400. The installation was very easy to do. This is a godsend, for we have just finished remodeling our basement. No more worries. Thank you very much!
Thank you for the quick shipment. I called the order in on Thursday afternoon and the pump kit was delivered to my door via UPS on Friday. I am very pleased with the RH-1400. Installation was pretty straight-forward and it works like a dream. I am very pleased with the unit itself and look forward to an "official" power-outage.
Alan C., NY
I purchased a RH1400 pump several years ago. It has served us very well during a sump failure and multiple
power outages. I can sleep at night without listening for the sump to come on!
Thanks for your help. This product was the best $400 I ever spent...
Russ M., Ohio
Thanks for a great pump! I installed the RB-750 which was quick and easy. It works like a champ! Attaching some pictures of the finished product.
Robert T., IL
Just completed installation of a RB-750 and everything went smoothly. I was pleased to see that everything necessary was included and the instructions were clear. Pump operates normally and works as advertised.
Also, I want to thank you for using environmentally friendly packing material. I will never have to spend time picking up starch peanuts from my front lawn. Thanks for doing the right thing for the environment!
Sincerely,
Michael B., IL
I installed the backup sump pump RB-750 myself and I am just a software engineer. It took me about 3.5 hours and it was not difficult at all. The hard part was going to the hardware store and picking up copper piping, a turn off valve and union. Made all the connections, turned the water on and the suction began and emptied the pit right away. I have ordered on Tuesday and installed in on Saturday morning!
Thanks,
Brett R., IN
Good morning. I recently purchased your Residential water-powered pump RB-750 and
had it installed last night. I would first like to comment on what a wonderful product this is and I thank
you for that. I am amazed how well it works!
Michael D., IL
Your service is excellent and I would recommend your company to anyone. The HB-1000 works
well and only a few days after I installed it, we had 2" of rain and as luck would have it, the power
was off for 3 hours. Needless to say the water driven pump did its job and saved my basement. It paid
for itself already, since my basement flood of July 1, 2010, caused about $11,000.00
damage. This a very good product which I recommend to everyone. The initial cost of purchase and installation
is a bit pricey (depending on your plumber) but, worth every penny and the beautiful part is there is no maintenance.
Thank you. I'm so glad I found your product.
Michael S., Saskatchewan
I purchased my HB-1000 last November and I am attaching a couple of pictures showing exactly how I installed my pump. I tested the performance of the pump and was blown away. It only takes about 20 seconds for the pump to remove all the water in my pit, almost as fast as the main pump. Your pump is great and I will recommend it to all my neighbors.
Tom O., MI
I installed the water-powered HB-1000 pump and expected when the pump was on, it would be loud. But the first time the water was turned on and the water in the sump lifted the float I actually got very worried because it was quiet and I didn't think it worked. Then, I noticed the water going down in the sump and had to get closer to the pump to hear it working.
I then put batteries into the water alarm so it lets me know when the pump is working. Thanks again for the great and quiet pump,
Philip B., Ohio
I am absolutely impressed with your Hi & Dry Water-Powered Backup Sump
Pump. After at least two frustrating experiences over the years with electric sump pumps that failed when
needed the most, resulting in a flooded basement I determined to solve the problem once and for all.
I decided
to renovate and completely remodel our basement, turning it into a movie room & entertainment
center (Man Cave). I held off doing the remodeling until I could find a solution that would ensure that the
basement would not flood again. Your Hi & Dry HB-1000 Sump Pump was the answer! I installed
the unit myself without any issues.
Well, guess what? It’s been raining cats and dogs for several hours and I am sitting here in the dark,
writing this email by flashlight, because we are without power. I can’t begin to describe how wonderful
it is to hear the valve on the Hi & Dry Pump activate and hearing the water run, knowing that it is draining
the sump crock and keeping my basement from flooding.
I have been fortunate in that we have not needed the
unit until tonight, which means it has sat dormant and been inactive for 3 years.
The extraordinarily good news is – it was
there when we needed it!
Congratulations on an exceptional product! I highly encourage anyone who is facing
a similar situation to spend the money, buy it and install it. This is one product that is a bargain at twice
the price. No Joke!
Chaz B., NY
FYI, I just installed my first HB1000 water-powered backup pump. I have never been impressed with the ones
my local plumbing wholesalers carry. I started researching different emergency pumps on line and was impressed
when I read about your product. As a professional plumber, I want the best possible product for my customers,
so I was willing to try your pump. The basement we installed it in had already flooded 2 times in one month.
It had the rinky-dink Zoeller emergency pump. The new installation was very easy! We were very impressed
with how fast the HB1000 removed the water in the crock! I feel the extra cost of this pump is worth it for
the protection of property and belongings.....not to mention, the stress of a flooded finished basement. We have attached pictures of our installation.
Charlie B., NY
I had a plumber install the CB-1500. with easy install kit. It was really quick, he loved it! And after having it for a few months, so do I. It works great and is very quiet. Attaching couple pictures of the installation.
Thanks,
Bob L., IL
One year our sump pump failed when we were on vacation. This resulted in 12" of water in our finished basement. Then we installed a backup pump with a battery power source. It worked fine until we had an extended power outage. My wife and I had to carry water in buckets up one flight of stairs for two hours. That's hard work when you're over 70 years old.
I told my wife, I wish we could find a way to pump water from the sump pit without needing power. I thought that was wishful thinking. Well my wish came true. I found a water-powered back-up sump pump on the Internet – the HB-1000 by RadonSeal. We purchased one and had it installed. It worked GREAT and only requires city water to operate. The other features that enticed us to buy this pump was that only the suction pipe and ball float is located in the sump pit. This lets room to service the primary sump pump.
The RadonSeal HB-1000 water-powered backup sump pump worked perfect when we tried it. The pump will be a stress relieving asset for our defense against flooding. We only wish we would have had this pump five years ago. Thanks RandonSeal for your fine products.

Cleaning concrete
After removing the original wood paneling (36 years old) from my basement walls, I found lots of thick efflorescence and lime build up over the years. After scrapping the the loose efflorescence, I sprayed the walls with the Efflorescence Cleaner and then applied coats of Radonseal Plus. The drywall contractor was very impressed with the before and after results. The basement walls feel and look dry.
Gregory R., CT
Your Universal Concrete Cleaner is amazing! It has quickly cleaned my old and dirty basement floor including my grimy shop area. Although I used a 5:1 dilution, it has even removed floor paint which I planned to strip later on. And best of all, it is not toxic!
Glenn H., MA
Just finished scrubbing my large, family room brick floor with your Novion Universal
Concrete Cleaner. I usually do this once or twice a year. The bricks are unsealed, cinnamon pavers. The floor is 32 years old. I tried a lot of different products for cleaning bricks. Yours is the best by far. The floor looks like it is brand new again. Both bricks and mortar are absolutely clean. There were no deposits left on top of the bricks as had happened with other products I've tried. Thanks very much for an excellent product.
Don G., PA
The paint stripper works great! I've been removing asphalt-based mastic from my 48 year old basement floor in preparation to put down ceramic tile. I had tried a different brand mastic remover for the job however the product and all the cleanup is solvent-based, which doesn't make it the easiest, safest or best thing to use indoors, and the mastic wants to soak into the concrete, not exactly what I trying to achieve. I even rented a electric rotary floor scraper to try to remove the mastic. Although it scraped some of it off, I still had a fairly significant amount left to remove. The Lightning Strip is definitely the best product I've found for the job. The mastic just melts with a little scrubbing, and the water cleanup is a real plus since it can be done with a mop and bucket, leaving the concrete relatively clean.
John Z., MD
Cheryl, Lightning Strip works great! I am removing paint stripes on my shop floors and have tried over 8 other products and they didn't work. Some I left on for 3 days, still didn't work. Within 5 minutes your product started to work with 1 coat.
Bruce W., MI
We are a commercial general contractor and had a project that required the carpet adhesive to be removed from the existing concrete floor. This area was previously a bank of offices approximately 2500 SF that was now to be a cleaned sealed concrete floor. We tried sanding and grinding the adhesive away, but this method did not work well. We were concerned about any solvents because of the odor involved and the safety problems associated. We tried the "Lightning Stripper" and it quickly and easily removed the old carpet adhesive completely from the concrete floor. The building was partially occupied with office staff during this process and they were not bothered by the odor. This was the perfect solution for our situation. I would recommend this product for commercial carpet adhesive removal.
R.H., Expedia Construction, IL
I applied the lightning strip to my basement floor last night and I was so happy to be able to peel large sheets of paint off easily. Tonight I'm going to spray it on the walls and I should be able to apply Radon Seal this weekend! Works great. The hardest part was get the cap off the Lightning Strip. Thank you for the excellent product!
Meigo K., NY
Hello, I purchased 8 gallons of your lightning stripper and it worked great!
Sushi Rei, CA
I wanted to tell you that you really have a great website, and I've already recommended it to 2 other people. You really did a great job explaining your products, and the Lightning Strip product you recommend also works really well. It actually does remove every bit of paint out of the pores of a concrete floor, which other products I've tried don't come close to accomplishing.
Carolyn S., KS
Customer Service
Your products work great, I have fixed leaks in several basements of houses I own. Your service to customers is great and ordering by phone is always pleasant and easy. Thank you for the great customer service!!!!!!!!!!!!!!!
Steve V, IL
Thank you for your prompt response it is refreshing. I saw some other products but definitely prefer dealing with a company that has great customer service and quick responses. Again thank you!
Wayne M., FL
Thanks Cheryl! Just as a note I thought the service I received when I placed my order was just awesome! Congrats,
Dr. Sandy B., Manitoba
I just wanted to send you a note to let you know what a nice experience I had dealing with a company where
service to the customer is still a priority. I had ordered the middle size pump and was concerned if it would
work ok with my flow rate, called you and you suggested to go down a model. Sent it back on Friday. Next Wednesday
I had my new pump and my refund credit to my account. Just great service and I wanted to say thank you. A
wonderful experience dealing with you and all made in the USA, for a change.

Several weeks ago I purchased one of your 4 pack CrackWeld kits to repair cracks in my concrete driveway. The kit was excellent. And when one of the mixing nozzles became clogged, you have mailed me a replacement right away free of charge. Thank you. Your products and your service are the best I have ever used.

Received the crack injection kit today. I was very satisfied with this transaction. You guys have your act together and provide great customer service. I would recommend you to others and will do business with you again.
