Crack Attack: Concrete Fixing for the Fearless.
If you follow the instructions, it works quickly and well. I was able to install 24 linear feet in an hour/1.5 hours. Allowed it to cure for 12 hours. Injected to thinner epoxy 12 hours later. Finished that process in less than an hour. Couple suggestions: make sure you cover over the crack thoroughly so you don't have leakage, when mixing the injectable epoxy, mixing the tube takes some finess to break the aluminum barrier and the screw in the mixer in the tube. Good luck!
It was easy to use, although mixing a small amount for each crack was a must. It firmed up overnight to an extremely hard surface.
I ordered this to apply on a 1/4" crack on the exposed foundation in my garage. The crack runs through the entire wall which is about 1' high. I covered the rear of the wall with cardboard so that the epoxy would not leak out the back. I inserted 3 of the injection ports into the crack and covered the rest with cardboard. Using my caulking gun I injected the epoxy mix into the ports starting from the bottom port. The smell from this is pretty strong so I had a fan blowing air across my work area. I let this sit for a couple days before removing the carboard. The epoxy worked in filling the crack and feels solid.
We applied this to a crack in our basement. It is the best thing we have found for sealing a crack in a wall. Would definitely recommend this for problem in basement wall!
