Product Review
The RadonSeal DIY Foundation Concrete Crack Repair Kit stops water leaks through hairline 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 for injection.
Our commercial-grade, two-component polyurethane forcefully expands and permanently fills the entire crack (up to 22-inch. thick walls). The closed-cell foam is impervious to moisture and soil gases, including radon. Tenaciously bonds to dry or wet concrete but remains flexible to allow for its natural movement. The crack will never leak again, unlike caulk or hydraulic cement. Enough to seal up to 10 linear ft. of cracks in poured concrete.
- Drill-Free Crack Repair: Advanced two-component low-pressure injection creates a durable, watertight seal that permanently repairs hairline cracks from the inside, eliminating the need for expensive repairs.
- Heavy-Duty Coverage: Low-viscosity urethane is specifically formulated to penetrate and seal even the smallest hairline cracks, ensuring a long-lasting permanent seal.
- Water-Resistant Seal: Formulated to remain flexible, accommodating natural concrete movement while its hydrophobic properties repel water, soil gases, and even radon, preventing shrinkage and deterioration over time.
- Easy to Apply: Easily apply the low-viscosity, two-component urethane using a standard caulking gun for professional-grade crack repairs with minimal effort.
- Trusted Quality: Engineered for professional-grade performance, RadonSeal products are proven to provide reliable quality and durability, ensuring strong, lasting results for foundations, walls, basement floors, and more.
- Use What the Pros Use: Save time & money using the same expanding foam crack filler used by waterproofing contractors.
