Penetrates into tight surfaces and even through a layer of latex paint. Great for waterproofing fiber reinforced and colored concrete. When applied as a secondary sealer after RadonSeal, the combination provides the tightest internal seal against water vapor before installing flooring.
The Homeowner's Solution To Repairing Foundation Cracks – Permanently repairs cracks in poured concrete walls by filling them with expanding urethane or epoxy. Stops or prevents water seepage. Low-pressure injection eliminates the need for drilling. Fills the full thickness of the wall and any voids behind it, so that water will never find the crack again. For hairline cracks or cracks up to 1/2" wide. Complete crack repair kits – you just need a caulking gun.
Contractor Repair Toolkits – Available in 30 FT and 60 FT sizes. For contractors or homeowners with multiple cracks in basement walls. Permanent crack repair. Fills cracks in poured concrete walls with expanding urethane or epoxy. Low-pressure injection eliminates the need for drilling and high-pressure machinery. Complete toolkits, including a dual-cartridge caulking gun.
Waterproof Leaky Wire-Ties, Waterlines, Pipes, and Penetrations – Permanently repairs leaking penetrations through poured concrete walls around pipes or conduits, as well as leaking form wire ties. Similar to crack injection with expanding urethane. Expands through the thickness of the wall and tenaciously adheres to concrete and plastic or metal pipes. Unlike mortar or hydraulic cement, will not get loose and start leaking water.
Floor Crack Repair Made Quick and Easy – Quick and easy repair of cracks in concrete slabs, driveways, patios, pool decks, and factory floors. No routing needed! Fast-curing. Rigid repair, stronger than concrete. Will stop the crack from moving, growing wider or longer. A definite must before re-surfacing concrete driveways to avoid the propagation of cracks through the new surface.
Flexible Repair for Control and Floor-To-Wall Joints – Use on saw-cut contraction control joints in concrete slabs or leaky floor-to-wall joints in basements. Protects joints against heavy traffic in factories. When mixed with sand, provides a rigid and permanent repair of cracked or leaking concrete blocks, spalled concrete floors or driveways, and large cracks or holes in concrete. Stronger than mortar or hydraulic cement and adheres tenaciously to concrete.

Give Your Concrete the "Tooth" It Needs – Industrial-strength concrete etcher and cleaner that is both user and concrete friendly. PowerEtch is powerful but non-corrosive to the skin and will not burn concrete. Low odor makes it ideal for indoor use. Use it to open up pores in hard-troweled concrete floors, to reduce pH, and clean concrete before applying penetrating sealers, water-based stains, paints, overlays, and coatings.
Concrete Etching Made Safe – An organic and biodegradable solution that prepares concrete surfaces for sealing, painting, or staining without the hazards of harsh acids. Etches tight surfaces, removes stains, and reduces the pH of new concrete.

Beats store prices – two-way shipping, testing, and official reports by email and mail included in price.
Did you know that most basements start leaking water within 10 to 15 years?
The telltale signs of basement moisture are efflorescence ("white powder") and musty odors. Finishing the basement traps water vapor seeping through the concrete, which causes molds and musty odors in many basements. Rising basement air then spreads molds and radon gas through the house.
You are not alone! Did you know:
Be Proactive! Protect your basement remodeling investment by first sealing the walls and floor against water and vapor, molds, and radon.
When trying to repair a wet basement or alleviate a damp one, you might get stuck in an endless cycle of waterproofing “fixes” that consume more time and more money.
Does Money Buy Basement Happiness?
You could hire a contractor to excavate, apply exterior waterproofing coating, and repair footing drains but that may cost you $15,000. And it will do little for water vapor oozing in through the basement floor. If you later install flooring, it will only trap moisture and promote the growth of molds and mildew. Floor tiles will “pop.” Similarly, a “de-watering channel system” that takes water seeping through the walls to a sump pump does nothing to stop moisture coming in through the floor.
So, you may decide on a sub-slab interior perimeter drain system with a sump pump (around $6,000) but it does little for moisture infiltrating through the walls. Humidity will remain high. You might buy a popular “waterproofing paint" sold in stores but as a latex-based paint, it is naturally porous and will let in water vapor. Soon enough, it will peel due to efflorescence and water pressure. And it cannot be used on floors.
Often, homeowners install a couple of dehumidifiers, costing around $90 a month to run. But dehumidifiers pull in more moisture through the concrete, making it more porous. Meanwhile, water increases concrete porosity, which will let in more vapor and radon gas. You might end up with a fan-based radon mitigation system (around $1,200).
Instead of all that, you can save time and money by protecting your investment and your family's health by simply sealing your basement floor and foundation walls with RadonSeal. RadonSeal Penetrating Concrete Sealer chemically reacts and permanently cures inside concrete (cement) both strengthening and sealing your basement against water vapor transmission, water seepage, radon, and soil gases.
As the US Environmental Protection Agency explains, there is no safe level of radon, a radioactive gas which causes lung cancer, the No. 1 cancer killer. Radon causes more deaths than fires, drownings, and airplane crashes combined.
People assume that the Action Level is like the safety limits on other carcinogens but the cancer risk from radon at 4 pCi/L is hundred times higher. The mortality risk is three times higher than the risk of dying in a car crash or the equivalent to smoking 10 cigarettes a day (US EPA). Among women, it increases the lung cancer risk by 50%.
The vast majority of radon-induced lung cancers occur in homes with radon concentrations below the 4 pCi/L Action Level. Children are particularly susceptible.
Reduce Your Home's Radon Level to a Minimum – Cancer risk is proportional to the radon level. Reducing radon from your current level by 50% lowers the cancer risk to each member of your family by 50%. Sealing your basement walls and basement floor with RadonSeal and making sure to repair/seal foundation cracks, floor cracks, gaps, and any easy pathways for radon to escape through can go a long way in reducing radon levels.

The Permanent Concrete Sealing Solution – Concrete paints, waterproofing sealers or cementitious coatings are a temporary fix only. They crack or peel and cannot stop gases or water vapor. Why not tackle the root cause of the problem? Seal those pesky pores inside concrete with RadonSeal and combine waterproofing, damp-proofing, mold remediation, and radon mitigation in one!
RadonSeal is Your Damp Proofing Solution!
Backed by a Lifetime Warranty – RadonSeal offers much more for your concrete than do common surface sealants that can be found in major hardware stores. RadonSeal is a permanent concrete sealer so you will never need to apply the product again! This water-based, clear, penetrating sealer will not leave a film or color on your concrete. RadonSeal works by sealing porous cementitious materials – indoor and outdoor, new and old; concrete, concrete blocks, cinder blocks, mortar, and stucco. Backed by a Limited Lifetime Warranty.
RadonSeal® Penetrating Concrete Sealer is deep-penetrating reactive concrete sealer that penetrates deep into concrete (up to 4"), reacts with lime and alkalis, forcefully expands inside capillaries, and hardens as an insoluble silicate mineral. (Silicates are the "binders" in concrete.)
The many benefits of sealing your concrete with RadonSeal® Penetrating Concrete Sealer:
Safe, Spray or Roll-On Application – Apply RadonSeal to your basement concrete using an airless sprayer, hand-pump "garden" sprayer, roller, or brush. RadonSeal is a waterborne concrete sealer – ZERO VOCs, no noxious fumes, non-toxic, nonflammable, and non-hazardous. The sealer absorbs inside the concrete leaving the surface slip resistant and paintable (does not change the appearance or profile of the concrete).
