Review: This is it! - 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.
Review: great product - Great product exactly as shown and delivery was efficient and smooth

## Questions & Answers

**Q: the crack on my wall is wider. maybe 1 inch. maybe more. would this product work?**
A: I had a fairly wide crack with a couple of 6" sections where pieces had come out and left at least a 1 1/2" wide void. I had some thin set (the cement kind NOT the premix which is not water proof) from ceramic tiling I had done and used that to embed and overcoat fiberglass drywall tape on those sections. I used the epoxy paste for the ports affixed to narrower places on the crack as well as the crack itself. It worked like a charm.

**Q: I bought this kit but i need more of the foam. Can I purchase extra tubes of the Hydrostop foam only?**
A: I don’t know, check with manufacturer👋

**Q: I have water seeping up around an iron sewer drain through the floor of my basement. Not a big gap around the pipe. Will this product seal the pipe?**
A: Troy,Disregard the other email I sent you.  I did not have all of this information.  You CANNOT use these materials on floor gaps and cracks.Thank you.

**Q: Is this Hydro Stop 300?**
A: Hydra Stop 300 is in the kit

### ⭐⭐⭐⭐⭐ Great value
*by S***B on 4 August 2025*

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.
