I don't think I will be able to tell for sure if the DB-100 fixed my leak until fall. Won't know for sure until the water level raises about a foot and there is no rain in sight. One good thing is that I still don't see any water seepage at the toe of my dam.

I've seen several posts where some people are using bentonite in conjunction with the DB-100/DB-200. How will they know if the bentonite or the DB-100/DB-200 fixed the problem? I'm starting to get a little more skeptical about whether or not my pond will hold once the water level rises since using bentonite in conjunction with the DB-100 was not recommended to my by the pond doctors.
