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.

Looks good so far....and it did the trick....fixed my leak.
I used this clay to fix a leak in my pond....thought it worked at first....but developed another leak close by....I think it must be the way I applied it...I just ordered another 25 pounds to to test this, and I guess we'll see what happens... Got another supply, went back out and applied the clay....and it did the trick....fixed my leak.....I just needed a little more clay to fix the problem.... I'm glad I used this product instead of starting some earth work.....

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.

Great Product, but doesn't work in the water.
The product is good, but I was uninformed by Google AI telling me it would stop a leak under water. Wrong! This product needs to be worked into the dry soil to work properly. I waste my money, not because the product was bad, but because I used it the wrong way. If you want a product to possible stop a leak without draining your pond or reservoir, check out Seek Leak. I used it and it worked.

Became slushy in water
It did not seem to swell up like a blockage that I expected, but I’ll give it some time. I needed only one third of it, so I may have wasted my money getting this only size available.

Repair leaks in a pond dam.
It appears to be working to seal the leak in the pond dam. Why did you pick this product vs others?: It was recommended by a friend.
