I purchased Hole Plug and granular Bentonite. Both seem to work well but one must give them time to work. Wish it wasn’t so expensive which I believe is mostly shipping expense. Having a local supplier, might reduce overall cost.
The product seams to work but for the price I would have thought I’d get the 10 bags I ordered instead of 8
Quick shipping and came as described
so far so good with service, still waiting for pond to get more full to add and help seal it up. . . new pond dig. .
Delivery went well, benseal works good
