Hiring a contractor to fix a leaky foundation crack can be costly, but RadonSeal DIY Foundation Crack Repair Kits provide an easy, affordable solution.
The low-pressure polyurethane injection expands to fill the entire crack, blocking groundwater leaks from the backside. No special skills are needed, just use a standard caulking gun and some patience.
Made with the same professional-grade, two-component polyurethane used by contractors, these kits ensure a flexible, waterproof repair that lasts. Once sealed, groundwater won’t find its way back.
The kits ship fully equipped with all the necessary materials to seal up to 10 feet of cracks in poured concrete walls, ensuring a hassle-free, professional-quality repair.
No special tools are needed to apply the material, just a standard caulking gun to inject the polyurethane foam and seal the crack effectively.
We offer kits in both 10-foot and 20-foot sizes, ensuring you have the right amount of material for your repair. Note: Single cartridges are sold separately.
Repairing cracks in poured concrete foundation basement walls has never been easier with RadonSeal DIY Foundation Wall Crack Repair Kits. Designed for homeowners, these kits use the same professional-grade, two-component polyurethane trusted by waterproofing contractors. Easily seal basement wall cracks yourself and prevent water leaks, saving you hundreds on foundation crack repair compared to hiring a contractor.
Many crack repair kits use single-component, hydrophilic foams that absorb moisture and deteriorate over time. RadonSeal DIY Foundation Wall Crack Repair Kits provide a superior, long-lasting solution with a hydrophobic, two-component polyurethane designed specifically for sealing cracks in poured concrete walls. Upon contact with water, the polyurethane expands up to 20 times its volume, ensuring a watertight, flexible seal throughout the crack. This flexibility allows it to withstand foundation movement without breaking down, making it an ideal choice for permanently sealing basement wall cracks and preventing water leaks.
Why pay for expensive professional repairs when you can permanently seal foundation cracks yourself? RadonSeal Foundation Crack Repair Kits are designed for easy, do-it-yourself application, requiring no special skills or experience. With clear, step-by-step instructions, all you need is a little patience and a couple of hours to seal cracks in poured concrete walls like a pro. Plus, if you ever need assistance, our team of experts is ready to guide you through the repair process. Stop water leaks, prevent further damage, and protect your home’s foundation.
Sealing basement wall cracks is key to protecting your home from water damage. Over time, cracks allow water to seep into your basement, causing moisture buildup, flooding, and potential structural issues. By sealing these cracks, you create a waterproof barrier that keeps your basement dry and preserves the integrity of your home.
Sealing basement wall cracks is an essential step in protecting your home from the harmful effects of moisture and soil intrusion. Cracks in your foundation can serve as entry points for water, which can seep into your basement. Proper crack sealing helps block these pathways while also improving the overall energy efficiency of your basement.
Sealing basement wall cracks helps protect flooring by preventing water intrusion at its source. When cracks are left unsealed, groundwater can seep through the walls, travel along the cove joint, or spread beneath flooring materials, leading to moisture damage, warping, and adhesive failure.
I have a horizontal crack. Can I still use the kit?
Most settling cracks are typically vertical or diagonal, which our kits are designed to repair. However, horizontal cracks in basement walls can be structural in nature and may require expert evaluation. For horizontal cracks, we recommend consulting an experienced contractor to assess the issue and determine the appropriate repair method. Therefore, we do not recommend using our kits for horizontal cracks without professional guidance.
Can I use these kits for repairing cracks in concrete block walls?
Our kits are specifically designed for repairing cracks in poured concrete walls. For cracks in hollow-core block foundation walls and mortar joints, we recommend our ElastiPoxy Joint & Crack Filler Kit. This two-component epoxy can be mixed with sand to create a strong, durable filler that effectively bonds and reinforces cracks in block foundations.
Can the kits be used for sealing slab and floor cracks?
Our kits are specifically designed for repairing cracks in poured concrete walls and are not recommended for slab or floor cracks. For sealing and structurally bonding cracks in concrete floors, we recommend using our CrackWeld Concrete Floor Crack Repair Kit.
Is it possible that I may not have enough material to fill 10 feet of cracks?
Each kit includes all necessary components to cover the specified coverage area. However, in some cases, additional urethane may be required to complete the job. Factors such as loose soil, voids behind the wall, wider-than-expected cracks, or cracks extending down to the footing can consume more urethane than anticipated. If more urethane is needed, individual cartridges—along with a new hose assembly, restrictor, and mixing nozzle—can be purchased separately.
I was only able to repair half the crack. Can I continue filling it later?
Yes, if you're unable to complete the injection process in one session, you can resume at a later time. The urethane is designed to bond to itself, ensuring a strong and continuous seal even if the application is paused.
Can the kits be used for sealing corner cracks?
Yes, the kits can be used to repair corner cracks. The injection ports are designed with a scored base, allowing them to be carefully bent for a better fit in tight corners. When placing the ports along a corner crack, hold them in place for a few extra moments to ensure the surface adhesive properly secures them.
Can I repair the crack if it is actively leaking water?
No, actively leaking water can interfere with the adhesion of the surface seal and the effectiveness of the injection process. Before proceeding, wait for the water flow to subside.
