I had my doubts about this kit… my crack extended about 7-8 feet and went from hairline to about 1/8-1/16”. One tube was enough, and above grade you could see the foam and outside the house through the crack. I haven’t had a drop of water since using this.

Unfortunately I ended up not being able to use this repair kit because I missed that it is designed specifically for poured concrete foundations and not block walls. That said, the kit itself actually seems very complete and professional, and the materials appear high quality and substantial compared to some cheaper repair options. The instructions were detailed and it definitely looks like a legitimate system for the proper application. I was specifically trying to repair a basement block wall crack, so this just was not compatible with my setup. Make sure to double check your foundation type before ordering.

This is a nice little kit to seal up small cracks and leaks in your basement. It will definitely not help foundational issues and you should be careful because some cracks are a result of bigger issues that are hidden. However, some minor cracking that’s just a little bit of water or gas could be fixed with a kit like this. I found it to be pretty easy to use overall and I do think it did help prevent the water from leaking back in although it’s only been a few weeks so we will see The leakage is definitely stopped. The kit is kind of versatile because you might be able to use it. Also on a retaining wall not just the basement. I would say overall a good belly for the money, especially if you are comparing it to hiring a contractor! Just remember that this is not a fix all our basement problems so be sure to keep an eye on it.

I purchased this basement and foundation wall repair kit to prepare some cracks in my basement concrete. This is a quality repair kit everything you need comes included. The instructions were easy to follow along and read I was able to repair my foundation in little time. I love how easy and convenient it was so you were able to inject the hyperflex grout material right into the crack. I was impressed with how well this completely sealed the crack and I know hunger have to worry about having it repaired

I received this repair kit because I needed to fix some wall cracks without hiring someone. Shipping was fast and everything inside looked well organized and good quality. The tools and materials felt sturdy. After using it, I was honestly surprised at how well it worked and how smooth the finish turned out. It’s holding up very well so far and blended in nicely with the wall. I would absolutely buy this again. It feels like a great value for the cost.

This kit includes everything needed to properly seal and reinforce cracks in basement or foundation surfaces. The materials feel durable and well packaged, and the instructions are straightforward. The sealant applies evenly and adheres securely once cured. It creates a reinforced finish that looks clean and professional. The 10 ft coverage makes it practical for longer repairs. A dependable solution for home maintenance and structural upkeep.
