It’s not the product I

It’s not the product I ordered my product was supposed to float and go to the hole to block it. I tried to Clay . It did not work.

Leak in the overflow

Stopped the small leak I had

★☆☆☆☆

Did not work for me.

Glenn C. · July 31, 2023Verified Buyer

I added the bentonite directly from the bag to a very small pond (5'x3') with flowing water in hopes of finding and sealing the leaks in the stone retaining wall. Did not work at all. I even attempted to add it to the exterior of the retaining wall and it just washed away. 25lbs wasted with absolutely no effect on the leaks.

Super, better than the stuff

David C. · July 9, 2023Verified Buyer

Super, better than the stuff I got last year to keep my little pond beside the driveway from leaking. It really seems to be doing the job and I put it in the little stream that feeds the pond.

Product arrived undamaged. The instructions

Mike S. · June 16, 2023Verified Buyer

Product arrived undamaged. The instructions sent to me on performing the bucket test were clear and the test proved the ability of the product to seal the dam face with recommended amount. Having knowledgeable staff added value to the test and any questions were addressed as we went along. As the amount needed is almost 25 tons of product, a precise test was excellent to verify ability of product to do the job with proper application.

So far so good

Alicia D. · July 17, 2022Verified Buyer

We used pond sealing clay last weekend on a 3 foot deep by 1 foot in diameter ground hog hole in the side of our levee on a 1/4 acre-ish farm pond. It seems to be holding only time will tell. We are experiencing a drought in west Tennessee and our pond is very low, seeping water is not as easy to detect. So far the pond repair is holding.

Small retention pond now retaining water again!

Patricia S. · May 31, 2022Verified Buyer

I have a very small retention pond that tends to leach water and had dried out. I raked Granular Bentonite Clay sealant in along the sides and bottom. Now the small pond (15') around is holding water again. Excellent Customer Service from NaturalWaterscapes.com and quick delivery of the product.
