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.
