I was wondering if anyone has ever used ESS-13 soil sealant to fix a leaking pond? I have researched all options and it seems to be the best for the money and it is guaranteed. Any input would be greatly appreciated. If anyone has used it which method was used: waterborne (when the pond is full) or dry method (when the pond is empty)?

If you have any luck I'd sure appreciate hearing about it. I had no luck with bentonite myself and was wondering about ess-13. A company representative advised me to try the bentonite because I had a rock bottom. I dug out enough rock to get at least 2ft. of clay everywhere but it still leaks. I might try the ess-13 now.
Good Luck
