This is a low pressure product - meaning that the "pressure" comes from VERY slow use of a caulk gun. That being said - this is an expanding foam type of product - it goes in as a very thin liquid and once activated foams and flls the crack - even hair line ones. The directions say that as long as you are below grade you do not have to seal the outside - well apparently the very top of our crack was above grade - when I went outside I could see the product had foamed to the outside. This means it went from a small hailine crack - through the wall - all the way to the exterior wall. I used this product to fill two areas with cracks that had leaked for a long time. It's been a few months now - and lots of rain - and we are still very dry. No drilling was required. I hope this helps. **Q: Can u use this product will water actively coming out of the wall or does it need to be dry? Once the solution is applied. do u need to wet the wa** A: Foundation cracks cannot be repair while actively leaking. The surface sealer and port adhesive requires a dry surface to properly cure and adhere. The injection foam can be used when the crack is wet. In fact, part if the injection process includes injecting water to assist in the foam expansion. **Q: What is the size of the port adhesive containers? eg ounces** A: Each jar is 8-ounces or .25 quarts. **Q: Have several cracks, some are substantial size, how much surface area does this kit cover?** A: ONE (1) RadonSeal® DIY Crack Injection Kit roughly fills 8-10 linear feet of cracks in poured concrete walls, from hairline to 1/2" wide. If there is a large void behind the wall or the urethane wastefully runs down towards the footings, it can consume more polyurethane foam, typically in the lowest injection port. You can order additional cartridges by calling RadonSeal®. Twenty-foot kits are available on Amazon®. ## Frequently Bought Together - 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 - Liquid Rubber Basement and Foundation Repair Sealant - Waterproof Concrete Sealer & Crack Filler - Flexible Coating for Indoor & Outdoor Use - Waterproofing Paint - Black, 5 Gallon - 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.sn/products/2392221-radonseal-diy-foundation-crack-repair-kit-10-ft-low-viscosity](https://www.desertcart.sn/products/2392221-radonseal-diy-foundation-crack-repair-kit-10-ft-low-viscosity) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-25*
