There is no issues in using the Flexomeric resins to repair older poured concrete foundations. **Q: Can this be used on a block foundation?** A: I don’t see why not. I usually drill holes about 7 inch spacing to get the resin in deep. Block is hollow but may be filled with cement so you may need extra resin which you can purchase. If the crack is wide then drilling may not be required. Good luck **Q: My crack is about an inch wide and about one ft in length. Can i still use this product?** A: The product says that it’s for cracks 1/16” to 1/2” wide. But it’s so easy and cheap compared to alternative fixes that I would still try it. **Q: How many feet does one kit cover?** A: I'd say 8-12 feet of crack. The deciding factor is the number of ports and the amount of epoxy, not the foam itself. And I was very happy with the kit. ## Frequently Bought Together - DIY Concrete Foundation Crack Repair Kit - Polyurethane Foam - 1/16" to 1/2" Wide Cracks - Low-Pressure Injection Method (FLEXKIT-100) - RadonSeal Complete DIY Foundation Crack Repair Kit - 10 Ft - Low-Viscosity Urethane Injection Sealant for Crawl Spaces & Concrete Basement Walls, Stops Water Leaks & Radon Gas, Drill-Free Filler - Applied Technologies 6-10' Fast Set Concrete Foundation Crack Repair Kit - Hydra Stop 300 Polyurethane Foam for Wall Cracks, Prevents Basement Flooding, Quick-Setting Waterproof Sealing Solution --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/16345678-diy-concrete-foundation-crack-repair-kit-polyurethane-foam-1-16](https://www.desertcart.sg/products/16345678-diy-concrete-foundation-crack-repair-kit-polyurethane-foam-1-16) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-11-08*
