Assessment of condition of an uncovered geosynthetic landfill bottom liner system
June 1st, 2020
By James L. Hanson and Nazlı Yeşiller Composite liner systems consisting of geomembranes (GMs) placed over geosynthetic clay liners (GCLs) commonly are used for containment applications. Such systems are used in base liners for ponds, reservoirs, basins and canals, and bottom and cover liner systems for landfill facilities. Even though the use of GCL-GM composites […]
