Geosynthetic Clay Liner Installation Image from Solmax
Geosynthetic clay liners (GCLs) have a tremendous record as hydraulic barriers in engineered lining and capping systems. Still, they are not necessarily well understood by the larger geotechnical design community. They require knowledge not only of geosynthetics but of sodium bentonite types, behavior, and suitability in certain applications. Dr. Craig Benson, Dean of the School of Engineering at the University...
