Corner Crack Repair Kit - DIY Concrete Foundation Crack Repair Kit - Polyurethane Foam - Hairline to 1/16" Wide Concrete Cracks - Low-Pressure Injection Method (FLEXKIT-201) with Corner Ports

Perfect for the hair corner crack I had in basement.

I wanted to like this product. Seems like it should work. Unfortunately the flexomeric210 does not expand at all. It does not fill gaps. Don't believe the short reviews. They are probably not real. Foolish me I tried this product twice. I know what I'm talking about. The two part epoxy sealant to initially adhere the ports to concrete worked but the expanding crack sealer was absolutely worthless. As you can see in the photo I tested it with a little water as recommended. Instead of expanding (like foam) it became like milk skin. Ineffectual. Don't waste your money. Use another epoxy product.

Horrible kit, very rudimentary, never made a good seal on the injection ports, the injection ports themselves are very difficult in getting a proper seal to working surface as they are sort of mesh near the base, also very easy to accidentally block with adhesive. Adhesive itself has a very short working time when mixed as directed. Resin is super thin, I had one injection port near the bottom fail, and then proceed to drain all of the resin onto the floor I had begun to apply at the top nearing the end of the job. First Resin tube failed inside caulk gun, emptying remaining 1/2 contents, was using light pressure.

Epoxy cement works. The injection was sloppy but the leak stop.
