Perfect. Filled crack in foundation and leak stopped immediately and has held up fine after 3 more storms. No leakage whatsoever.

Worked perfect on the bottom edge where the floor and walls meet, had micro holes that water was coming though. Put a 1/2 chamfer all the way around and so far it has sealed up everything perfectly.
