Penetrating concrete sealers | Do-it-yourself basement waterproofing | Basement and concrete repairs
Whether your an architect, contractor, or radon specialist or a DIY homeowner in need of basement waterproofing sealers and repair materials, you can count on RadonSeal® for the best solutions for your waterproofing needs! Our expertise in solving issues, such as damp basements, radon mitigation, masonry preservation, repair of indoor and outdoor concrete, brick, and masonry is what has set us apart from the rest.
Did you know wintertime is the best time to seal your indoor and basement concrete! Radon levels in homes surge during the heating season and people spend more time in their homes and basement, breathing in elevated levels of radon gas and unhealthy concrete dust. Heavy rains and snowmelt may also start water seepage and increase the chance of mold growth in your basement.
You can protect your investment and your family's health by simply sealing your basement floor and foundation walls with RadonSeal®. RadonSeal® chemically reacts and permanently cures inside concrete (cement) both strengthening and sealing your basement against water vapor transmission, water seepage, radon, and soil gases.
The #1 Concrete Sealer – Penetrates and permanently seals indoor and outdoor poured concrete, and concrete blocks against water vapor, water seepage, efflorescence, and even radon gas! Resists hydrostatic pressure. Strengthens, densifies, prevents spalling, cracking, dusting. Use for sealing basement walls, basement floors, slab-on-grade (before installing flooring or carpeting), crawlspaces, garage floor, warehouse floors, parking areas. Slip-resistant. Paintable. Water-based. Zero VOCs. Permeable. Money-Back Lifetime Guarantee!
Concrete Stain and Penetrating Sealer in One – Both waterproofs and stains concrete in one simple step! Preserve and beautify your outdoor or indoor concrete, commercial or residential.

Slip-resistant. Sealer is backed by an aggressive 15-Year Waterproofing Guarantee.
Deep Seal Your Brick and Masonry – LastiSeal is commonly used for sealing and strengthening brick and mortar but can be used on a wide variety of cementitious materials. Waterproofs stone veneers, stone, stucco, plaster, grout, and porous tiles. Penetrates up to 4". Leaves no coating on the surface. Permeable. Use for sealing chimneys, brick foundation walls, fireplace, retaining walls, splitface blocks, and even wood! Low-gloss optional. Water-based. SAFE! Backed by a 15-Year Waterproofing Guarantee.
Protects Concrete Driveways, Sidewalks, and Patios from Water Penetration – DryWay beads and protects your outdoor concrete and masonry against the penetration of surface water, rain, chemical spills, road salts, and de-icing chemicals. Lessens the bond of snow and ice. Spills wipe off easily leading to less maintenance. DryWay will not change the friction or appearance of the surface. Breathable, vapor permeable sealer. Zero fumes and VOCs. Use for sealing driveways, garage floors, autobody repair shops, patios, sidewalks, stadium seating, pool decks, seawalls, and commercial walls, and slabs over living spaces.
The Industrial Concrete Sealer – Penetrates deep into concrete or masonry. Forms a subsurface waterproof barrier against surface water and negative-side hydrostatic water pressure, road salts, and chemicals. PERMANENT. Its small molecules allow it to penetrate into tight surfaces and even through a single layer of latex paint. Great for waterproofing fibercrete and colored concrete. When applied as a secondary sealer after RadonSeal, the combination provides the tightest internal seal against water vapor before installing flooring. "It's like deep-filling the pores in concrete with silicone caulk."
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.
Repair Leaky Wire-Ties 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 – Flexible repair of saw-cut contraction control joints in concrete floors or driveways. Protects the joints against heavy traffic in factories. For permanent repair of floor-to-wall joints in basements.

Concrete Moisture Test Kits – Make sure to test moisture vapor transmission and pH of the concrete slab before installing moisture-sensitive flooring on concrete floors or coating floors with epoxy. If needed, seal the concrete with RadonSeal penetrating concrete sealer. For even a tighter seal, follow up with Ion-Bond Armor concrete sealer.
Test Your Home For Radon Levels – Healthy home, healthy family! US EPA recommends testing for radon in indoor air every year or two. EPA approved short-term radon in air test kits or long-term test kits for more reliable results. Radon-in-water test kits. Beats store prices – two-way shipping, testing, and official reports by email and mail included in price.
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 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 (say, $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 (say, $1,200).
Instead of all that, save money and time by simply sealing the basement walls and floor permanently with RadonSeal® Penetrating Concrete Sealer and, if necessary, seal cracks with our concrete crack repair kits.
As the US Environmental Protection Agency explains, there is no safe level of this radioactive gas which causes lung cancer, the No. 1 killer among cancers. Radon causes more deaths than fires, drownings, and airplane crashes combined!
Homeowners assume that the "Action Level" is safe but it is equivalent to smoking 10 cigarettes a day (US EPA) and the mortality risk is three times higher than the risk of dying in a car crash. The vast majority of radon-induced lung cancers occur in homes with radon concentrations below the "Action Level."
Reduce Your Home's Radon Level to a Minimum – Reducing radon from your current level by 50% (or 90%) will lower the cancer risk to your family by 50% (or 90%). Seal your basement floor and walls with RadonSeal and make sure to seal any cracks, gaps, or openings. Visit How Radon Gets Into Homes

Well, your not alone! Most basements start leaking water within 10 to 15 years and a musty, damp basement is by far the #1 complaint of homeowners we hear from. Did you know...
We recommend you be proactive and take the proper steps to protect your concrete before it starts leaking. The first step to DIY basement waterproofing is that you must first seal your foundation walls and floor against water vapor transmission, water seepage, mold, and radon. RadonSeal® Concrete Sealer is an easy and economical solution to help aid in your basement waterproofing project.
Unlike concrete "sealers" or paints sold in stores, our line of eco-friendly, penetrating concrete, brick, and masonry sealers provide permanent or at least long-lasting solutions for your waterproofing needs. Our sealers are typically used on projects such as:
Reducing Humidity is the Key! Your basement or foundation slab is by far the single largest source of humidity in your home – several times more than showering and cooking combined! Molds and mildew, fungi, bacteria, and dust mites flourish in high humidity (over 50-60%). They cause allergies, asthma, airways infections, and other health problems.
The All-Natural Solution to Cleaning Mold and Mildew – Use BioZap Mold & Mildew Cleaner to get rid of visible molds. Place several jars of BioZap™ Air Purifier & Deodorizer against all the invisible molds and spores floating in the air or hiding in porous surfaces. BioZap also eliminates musty odors.
For long-term mold prevention, make sure to seal your basement walls and floor with RadonSeal Penetrating Sealer to minimize water vapor transmission through the concrete. And repair or seal all cracks, gaps, and openings.
