Hydra Stop 300 Fast Set Crack Injection Kit, 10ft

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

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.

Same kit that professionals use to seal cracks in poured concrete basement walls. Make sure you follow the included instructions. Neatness counts. Has been several years since I had to use this and have had no recurrence of water leaking through the crack.

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.
