Granular Bentonite Clay for Pond Sealing - 25 pounds

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.

"Waterproof Solutions" wanted to charge me $3500 to put in a french drain to make my basement stop leaking. The bag of Bentonite was hard to find anywhere but Walmart had it online for $80. I poured the bentonite along my outer foundation wall and in a puddle and the basement leaks have almost completely stopped.

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.

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.

Work perfect! No more leak.

Stopped the small leak I had

works great

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.

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.
