users of db100 and db200 any real success stories yet? i am pondering several approaches to trying to fix my leaking dam--dam is steep on pond side but i think i would do best by tying my fix into the 2' red clay we lined bottom with last year--now thinking of waiting till water falls or draining down below edge of red clay liner--then after it drys enough rototill db200 and bentonite(s.kitty/etc) mixture into the wall of the dam to tie it into the clay bottom--and continue that up wall of the dam to the level of the siphon. i really hate to think about recoring 1/2 the dam.
