Abstract

This paper presents the results of an experimental investigation on gas leakage through a geomembrane (GMB)/geosynthetic clay liner (GCL) composite liner where the GMB contained a circular defect and the GCL was partially hydrated. The results indicate that gas leakage rate increased with increasing gas differential pressure and increase of the GCL total suction. It was also observed that gas leakage rate reduced with the increase of the gravimetric water content of the GCL.
