Have not worked any projects on dry application yet. It's not designed for dry application - BUT, they indicated folks have used it in conjunction with bentonite and also just the polymer with good results. Till into top 4" clay, then compact with 18-24" clay in 6" lifts. As soon as one of these projects is attempted I will include the forum on the process and results.
Rats. No clay locally, all sand. If I had good clay to compact in 6" lifts I wouldn't need it.......
I was going to dig a few 1/10 & 1/20 acre ponds in the sandy soil. No clay on site until 22' down..... I wasn't going to make them that deep.......
