ABSTRACT:
A mixture of swellable clay, such as bentonite, is charged with an additive which provides an excess of univalent ions which tend to neutralize the deleterious effects of ions which are naturally present in seawater. The mixture is deposited on and carried by a sheet to facilitate its uses as a pond liner or a foundation sealant.
