I called and talked to Kenneth Williams, the guy that wrote that article "Stopping Leaks in Ponds" from Langston University.
While we were dicussing his article he said that you can even use agacultural lime to stop leaks in ponds using the sprikle method.
He said spread it 6" thick over the area needing to be sealed. He said that the lime's small particles and filler which is often types of clay, can work like bentonite without the expansion properties.
This sounds like a much less exspensive option than bentonite.
Does anybody here have nay ideas about this or have heard of this being done?
