Product Review

The RadonSeal® DIY Foundation Concrete Crack Repair Kit stops water leaks through hariline or large cracks in concrete foundation walls using state-of-the-art low-pressure injection. NO DRILLING REQUIRED! A complete crack injection kit for homeowners or contractors. Only a conventional caulking gun needed. Two-component polyurethane forcefully expands and permanently fills the entire crack (up to 22-inch. thick walls). Tenaciously bonds to dry or wet concrete but remains flexible to allow for its natural movement. Will never leak again, unlike caulk or hydraulic cement. Enough to seal up to 20 linear ft. of cracks in poured concrete.
