One more thing, bentonite basically forms it's own seal so to speak. If one tills it into the soil they would also most likely need it added on top of the tilled in area. When building a pond, everyone is told you will need clay in the pond bottom, so u look for thick clay layers when pond building. Bentonite is clay, build a thick layer so to speak.


Do not judge me by the politicians in my City, State or Federal Government.
