Satisfying to watch

Would Recommend

We’ve had an ungodly amount of rain this spring. Used for small leak in basement wall. I had to chisel out the crack where water was leaking to make a larger working area. The leak was active when I applied the hydraulic cement and it was so satisfying watching it stop. I used painters tape to maintain clean lines. Removed the tape while cement was still wet.

Perfect for sealing foundation

Would Recommend

I bought this to seal up my foundation around a pipe. After mixing according to the instructions, I found it easiest to place it using my hands (wear rubber gloves). It sets very quickly, so don't try to apply too much at one time. Smooth with a trowel. It worked great.

Cracks in basement floor

Would Recommend

I had cracks in my basement floor that rarely leaked but whenever it rained for multiple days and the ground got saturated it bubbled up through the crack and flooded the basement. I Veed out the crack one inch deep and filled it with this leak stopper and it's never flooded since then.
