Hydra Stop 300 Fast Set Crack Injection Kit, 10ft

I'm not much of a product reviewer but I have to share the amazing result of this product. We are the new owners or a 70 year old suburban ranch with a poured concrete basement. Past owners have added structural braces to address the wall folding in from hydraulic pressure over the years. Our current circumstances are water in the basement with a heavy rain. Searching online I found recommendations for Hydra Stop so we gave it a try. Past unsuccessful repairs were excavated and following the detailed instructions we installed the first kit. Next rain the original leaks were addressed but they moved farther down the horizontal crack so I ordered another kit. This crack was much smaller and we the experience of the first kit we were able to extend the repair. Next rain and our basement is dry! We also cleaned the rain gutters and plan to regrade the yard to keep water away from the foundation but I am impressed that Hydra Stop was effective without this other corrective work. Installation can be messy so use all of the PPE and plastic drop cloth provided in the kit. Don't freak out if the foam you inject come out of spaces you didn't expect. Just let it cure and then scrape off with a putty knife. The attached photo are a real world installation as compared to the product demo videos online. Bottom line is this is a very effective product to address ground water entering through foundation cracks even when installed by DIY'ers. I would recommend to a friend.

Great product exactly as shown and delivery was efficient and smooth

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.

I’m not a professional anything, but I had a leak in my basement and the professionals who did evaluate it basically tried to continuously sell me smoke and mirrors. I was interested in this stuff because in my previous dwelling there was a crack filled with something similar that the home inspector seemed to feel was totally legit, so I thought I’d try it for my new problem - a 7ish’ vertical hairline crack in my foundation that leaked a little with every rain and a lot with very heavy downpours. I was sure I would get started and run into a roadblock despite reading through the entire instructions in all languages presented, but really it was pretty straight forward and worked well. Best of all there is no more flooding in the basement, and I live on the East Coast which has basically seen heavy rains daily for much of the summer this year. As in ZERO water coming from this crack!!! The only unexpected issue with using this stuff was that I apparently didn’t completely seal the wall with the putty, and so when I started injecting the sealant, instead of it coming out the ports, it started coming out all over the place. So I would just caution to be liberal with the first step to minimize wasting the sealant when you start injecting it. I would definitely highly recommend this stuff if appropriate for your problem - much better to spend $150 and a couple of hours than $5k on a local “expert”, especially if the latter doesn’t even fix the problem! Update Dec 2023 (almost 3 years and many heavy rains later) - still going strong!

This kit worked, but it would be better if they just sold the ports, epoxy, and urethane. The caulk gun that comes with this kit is completely useless for this purpose. You will not get ANY epoxy out of the tube with it before it bends and breaks. It's a $3 caulk gun, so compared to the price of the kit it's not a big deal. Use your own. Pneumatic would be good here. The wire brush is what you would expect, but it was a waste for me because I already have one. The tongue depressor mixers are actually quite good for spreading the epoxy over the outside of the crack and attaching the ports. I was prepared with a disposable putty knife, but didn't end up using it, because the sticks were the right tool for the job. The goggles are el-cheapo, and any respectable craftsman will have a better, more comfortable pair already. This kit is sold as a 10' kit, and you are supposed to place a port every 6" (4" from the bottom). Mine came with 15 non-corner ports, and one was broken. Luckily I only had a 7' crack to seal. All that said, this still gets four stars, because it worked extremely well. The epoxy was easy to mix, and securely attached the ports to the wall with no drilling. Covering the crack with it prevented any foam from leaking out the face of the crack on the inside (except at the top, because I didn't think to seal the crack on the top of the foundation). It has exactly the right consistency to easily feather out and blend with the wall (anybody looking at it is going to be able to tell you sealed a crack though... No way around it.) Injecting the foam was slow, but simple, and mess-free. It took ~5 minutes per port before the foam would start coming out the next port up. (My crack was ~1/8" at the top tapering down to 1/16"). I know it worked because water stopped pouring in like a faucet in the rain, and because I can see where the foam expanded out of the crack on the outside of the 10" thick foundation. The local guys all wanted ~$500 to do this job, and it's so easy I'm glad I did it myself.
