pond leak repair
worked well to fix a pond leak

Need several bags for any results
Decent sealant for my pond leak. Granular sodium bentonite helped slow the pond leak, but required more quantity than expected. Works better for smaller leaks, I think. Still, a helpful natural solution. 3 stars

Works well to seal leaks in ponds
This product has really helped my leaking pond. Even though I added it with water in the pond, it has made quite a difference. Easy to use and effective.

Make sure to let it dwell for 20 min before using
Used this as a slurry coat with concrete on a concrete pond. It worked well but milked the water a lot. Put a dirt coat on the surface. Resolved the issue. It did a very effective job on the fixing the leak.
