RadonSeal Easy-Peel DIY Concrete Foundation Crack Repair Kit - Easy to Remove Surface Sealer Makes Clean-Up a Breeze (20-Foot Kit)

The RadonSeal EASY-PEEL DIY Concrete Foundation Crack Repair Kit (20 ft) is designed for repairing hairline and wider cracks in poured concrete foundation walls, including basement walls and retaining walls, using a controlled low-pressure injection method. This larger-capacity kit is ideal for homeowners and contractors handling multiple cracks or longer repairs. A unique easy-peel surface sealer allows for clean removal in a single strip after the repair is complete, eliminating the need for scraping or grinding. The system is simple to use and requires only a standard caulking gun—no specialized tools needed. The included two-component polyurethane expands within the crack to fill internal voids and bond to both dry and damp concrete surfaces. After curing, the material remains flexible to accommodate normal structural movement. Formulated specifically for poured concrete (not for block or masonry walls), this kit is well-suited for basement foundations and other structural concrete applications. With enough material to repair up to 20 linear feet of cracks, it is ideal for larger projects while still maintaining precise, low-pressure control for consistent results. Coverage is approximate and may vary based on crack width, depth, and job-site conditions.
