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

Q: the crack on my wall is wider. maybe 1 inch. maybe more. would this product work?

I had a fairly wide crack with a couple of 6" sections where pieces had come out and left at least a 1 1/2" wide void. I had some thin set (the cement kind NOT the premix which is not water proof) from ceramic tiling I had done and used that to embed and overcoat fiberglass drywall tape on those sections. I used the epoxy paste for the ports affixed to narrower places on the crack as well as the crack itself. It worked like a charm.

Q: I bought this kit but i need more of the foam. Can I purchase extra tubes of the Hydrostop foam only?

I don’t know, check with manufacturer👋

Q: I have water seeping up around an iron sewer drain through the floor of my basement. Not a big gap around the pipe. Will this product seal the pipe?

Troy,Disregard the other email I sent you. I did not have all of this information. You CANNOT use these materials on floor gaps and cracks.Thank you.
