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 product works! It is relatively easy for a DIYer. The instruction videos are a big help. Be patient with the injection foam sealant, it will come out of the next port up in a few minutes. Had a torrential rain three days after repair was made...NO LEAK!!

Excellent productThe instructions was easy to understandAll necessary tools are providedI would buy this product again

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.

Finally, no more water or moisture after 2 years of slow water leak into basement. This kit did the job and saved me over $10k of expenses.Starting at least a couple years ago, small amounts of water would leak into a section of my finished basement during moderate to heavy rains. Not much water, but enough to leave a puddle or more, and require a wet/dry vac and floor fan each time. My house was built in 1999; poured concrete basement walls.Adding dirt grading outside the house did almost nothing to help. Diverting the downspouts 10 feet away from the house helped with moderate rains. But any heavy rain or a plugged up gutter would instantly bring a big puddle of water inside.I was told by multiple contractors that deep excavation of the exterior ground was required to find the crack and seal it. One estimate was at least $10,000 just for the initial excavation!I found this kit and the video online. I had a hard time believing it. But $150 was worth a shot. I opened up the dry wall expecting to maybe find a 6” crack. No! There was a crack; and it extended from the floor to the top of the concrete wall! Almost 10 feet!I followed the video instructions. The whole process, in total, took less that 2 hours of my time. The kit contains literally EVERYTHING you need, except for tap water! 😊 It even included the wire brush for cleaning the surface.Mix small amounts of the epoxy at a time; it starts hardening with 5 or so minutes. Make sure you are liberal with the application of the epoxy. This is to make sure there are no cracks/leakage points when injecting the resin.It worked! My basement has remained bone dry. Even with the downspouts no longer diverted and several long lasting torrential downpours of rain. I even soaked the exterior at the wall for 20-30 minutes with a garden hose. No exterior excavation or other corrections required.This interior-only solution work!

This stuff worked pretty well. I used it in a couple of places, one of which always leaked when there was a big rain. We've had one big rain since and that spot did not leak this time. So far so good. A few things to know, however.1) I spaced my ports about 4 inches apart and nothing ever squirted out of them as I was filling the one next to it. When you squirt in water, the instructions say to watch water come out the port directly below. Never did. Also when you inject the polyurethane foam, the instructions say to watch it come out of the port directly above. Never did.2) When you open the box, the tubes of epoxy and polyurethane foam appear completely full, but in reality they are only 50% full. If you look closely you can see they are designed that way. The plunger inside takes up about half of the tube. I didn't figure this out until I started injecting the polyurethane foam in the first port. I wasted a large amount of that first poly foam tube and ended up burning through both tubes. I still have plenty of epoxy left over.3) The caulk gun they provide seems sturdy at first but the spring on the trigger failed pretty quickly, which made that caulk gun useless. I switched to my own caulk gun, which worked fine. My guess is if you order this kit you probably already own things like a caulk gun and goggles so those could probably be left out of this kit and the price could be a little lower.Other than that this is a good solution to a common problem and I am happy to spend a fraction of what it would cost to have a professional come in and take care of these foundation cracks.
