Awesome stuff, I used it to fill holes used from animals going under my cement driveway and walkway. Fantastic results and hardens like a rock

Works well. Be quick and ready for it, it expands quickly and will come for you if you're not prepared to control it.

Being a more dense foam I was hoping for more expansion but it did the job. I used this to repair my pool steps from where improper install caused the dirt to wash out underneath them. This filled the void well.
