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

This is an amazing kit to stop water coming in through cracks in a basement concrete wall! I fixed a crack 14 years ago with this kit and there is no sign of water in the basement to this day. The repair is done completely from the inside so no digging outside. Installs fast and easy. The expanding foam is so powerful that it pushes completely through the crack to the outside of the basement wall. If you have a crack in a basement concrete wall and water is coming in and the crack is hairline to 3/16” (or probably much bigger) this kit is for you. No need read further. You’ve found the solution. I’ve bought 3 kits for 3 different cracks.

Great product exactly as shown and delivery was efficient and smooth

Saved me thousands of dollars! I had a leak in my basement and hired a contractor to repair water damage. He Recomended this two part epoxy kit as he has used it with success in other situations. As the crack was inaccessible outside due to a 1,000 sqft deck needing to be ripped out to get to the affected area I gave this a try. So far so good, as we have had a few heavy rains and in both areas we had no problems with leaks anymore. I covered both cracks with carbon fiber “tape” and epoxy as an added layer of protection as the basement will be finished eventually. Only thing I can advise is take your time on the prep, align the ports properly and follow the directions and it will work. Saved thousands by doing it myself.

Arrived quicker than expected. The kit contained everything i needed to complete the job. I found the instruction videos helpful and easy to follow. There was plenty of epoxy and sealant to fix a crack in my poured concrete foundation that was about ⅛" wide and ran from a foot from the floor all the way to the top. I let the epoxy set overnight to be sure. I had no leaks this Spring. The kit is pricey but was still a fraction the cost of hiring someone. Hopefully it lasts for years to come.

Very good quality crack repair kit. Enough for more than 10’ of crack. Frankly, if the crack sealant is out, you can use any way to seal the crack from outside and then use the foam to seal it. The only reason why I gave it 4 stars is because its very difficult to use the corner injectors. Its not easy to stick the corner injectors on corner cracks on concrete. I have used this product at least twice in the last 3 years and it seems they haven’t improved the corner injector design.
