Geosynthetic Clay Liners

This text, based on an international symposium held in 1994, covers geosynthetic clay liners (GCL), a type of geosynthetic material which blends natural soil and geosynthetics in the form of a composite barrier-system. Environmental applications have been a major use of GCL.
