Treat area available underwater - wait for rain event, treat remaining area. Without supplemental irrigation source it poses a challenge. Product must be hydrated to activate and hydraulic pressure helps form seal, too.

Yes, can be used like bentonite and incorporated into soils 4" down, then should plate clay in 6" lifts. One could incorporate into exposed banks 4" depth and wait for rains. It would activate when hydrated. I haven't performed this project yet, but imagine it would work. Might be the only solution for some folks dependent on infrequent precipitation and a half full pond.

Feel free to reach out anytime for a chat. So much to relate, so slow typing! I am here to help anyone regardless of the issue or solution!
