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

I purchased two of these kits to repair settling cracks in my basement foundation. The kits work great. It is important to follow the instructions as little mistakes can create issues when filling the crack with the expanding foam product. Total time from start to finish is about 2 hours, which includes about 45 minutes for the epoxy to harden.

We have been contending with a foundation crack for over 40 years. We literally had water pouring through the wall like a fountain. I've spent countless nights vacuuming water and ringing wet towels...not wanting to pay the $10,000+ that contractors were asking. The crack we had was ⅜ to ½ inch deep in some places, so we needed to buy a separate kit of epoxy ($50).All Together we spent:$150 for this kit$50 for the extra epoxy$50 for DryLock paint.For most applications, I would venture to guess that just the kit alone would suffice. It's important to follow the instructions and be patient.There are few products that I feel excited telling others about...this is definitely one of them.

Overall I am pretty happy with the kit. Actually doing the work was pretty straight forward, but for sure watch the video. I didn’t read the instructions but watched the video before and while doing the work and it was pretty straight forward. A few callouts:1. You don’t need a of the gray sealer to apply the ports, less than the video IMO. You’ll need more if doing corners for sure but not a ton for just a single plane.2. The working time on the gray sealer was pretty short, so plan to do this in small batches.3. The back plunger in the Hydra Stop 300 is pretty large. I thought that it had hardened on me and spent a ton of time trying to crank down on the caulk gun, when really it was out of product. Lesson learned.4. I had 2 cracks to fill, a 6’ and a 4’ crack. I’m the end I needed 2 kits to do this. The cracks weren’t larger than 3/16” at the largest, so you may want to plan ahead and get 2 or the larger kit if you have a larger crack.5. Do keep in mind this will work through to your exterior, specifically where above grade. So plan to address that if you care. It’s paintable so not a huge deal, but something to consider.I can’t speak to performance, and hope I won’t need to. I did some downspout rerouting, this was more for peace of mind. So far, so good!

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!!

I had to wait a few months for our weather to switch from snow to rain. After a solid 2” of rain in two days, this absolutely worked. The application was a little messy, and I may have popped one of the ports off, but the end result was a completely sealed crack. I’m incredibly impressed with how well this worked.

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

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!

. Two tubes of paste were not nearly enough and two tubes of hydra stop 300 didn’t fill 2ft long crack in an 8 inch wall. Now I’ve got a half finished project with no way to finish in time. Not happy!!! I’m a technician and wrote a tech column internationally for 10 years. I followed all directions yet the process was a bust. Really a waste of time and money
