Landfill cap design with geosynthetic clay liners

Geosynthetic Clay Liners (GCL) are mainly used in landfill caps and closures. In these applications the capping system is exposed to low confining stresses, differential settlement, possible temperature effects and to shear stress on slopes. Installed GCLs must not only withstand the mentioned stresses, but also withstand the installation procedure without any harm. These important design factors as well as the durability aspect are topic in this publication.
