摘要：

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