Is GSE GundSeal GCLs compatible with all leachates and waste streams?
No. The compatibility of the bentonite coating of GSE GundSeal GCL with the leachate or waste stream must be evaluated for each application. Sodium bentonite is compatible with many chemicals and compounds. However, the swelling and permeability of sodium bentonite is negatively affected in the presence of liquids containing concentrated salts (such as brines), concentrated organic solutions (such as hydrocarbons), divalent cation concentrations (such as Ca++ and Mg++), and strong acids (pH <5) or bases (pH>11).
