  • So far, so good!
My husband purchased this to repair a large crack in our foundation that was not covered under the builder's warranty. How a large crack, allowing water to flood a basement is not "structural", I'll never know! The crack was fairly extensive -- from the ceiling to the floor of our poured concrete foundation. After research, my husband purchased this kit, carefully read the instructions (which he said could have been better) and went to work. He did mention the tools provided in the kit could be better but he made it work. It has been several weeks now, with additional heavy rain and no leaks. Otherwise, The only downside to this process for me was the strong smell for the first few days. I literally could not go down the basement until it dissipated! My husband has shared this project with several of his friends and they have all called to ask about it because they also have foundation cracks. The note is just his note of when he did the repair! ... show more

  • Difficult product to use
This product is quite difficult to use. The 2 part epoxy putty is very thick, and cures very very quickly (within 10 mins of mixing), making the rest of the batch goes to waste. Also it smells horrible and would stink up the entire basement. The epoxy is also hard to apply evenly, this can result in leaky spots. If you buy this kit, make sure you get a bag of small plastic putty knife. The injection epoxy itself seems ok, you need to inject quickly otherwise it would cure in mixing nozzle or the flex tube. Yet some of the epoxy that got on the floor takes hours to cure which is strange. My biggest complaint is the putty, it’s really not usable with the cure time it has. ... show more
