Abstract

Geosynthetics are widely used in waste containment applications. Geomembranes are used as a components of base, side and capping systems. Geosynthetic clay liners (GCLs), are one of the geosynthetic materials undergoing rapid growth in usage, and are being employed as a substitute for compacted clay liners. Geosynthetic erosion control materials are being used to stabilize the surface of cover systems. Geonet and geocomposite drainage materials are used on the side slopes of base liners and in capping systems as collection systems. Geotextiles are commonly used as separators and filters between earthen materials and as cushions to protect geomembranes from puncture. Geogrids are employed principally to strengthen liner systems when subsidence is expected, and to improve the sliding stability of geosynthetic veneer systems on slopes. This paper presents a brief overview of the use of geosynthetics and issues related to their consideration for landfills.
