[TowerTalk] Making a better Ground

[Bill Aycock]

Mike-
Don't be confused by references to "Fullers Earth"; Bentonite and Fullers 
Earth behave VERY differently. Chemical similarity does not make them work 
the same way. Bentonite's value is in the behavior with water.  Like all 
clays, it swells when wet; Bentonite, however, swells a LOT. This is why it 
is used to seal ponds and below-grade walls.  In water, it forms a 
Thixotropic gell.
