Geosynthetics in Landfills

Geosynthetics are extensively used in the design of both base and cover liner systems of
landfill facilities. This includes:
• geogrids, which can be used to reinforce slopes beneath the waste as well as to reinforce
cover soils above geomembranes;
• geonets, which can be used for in-plane drainage;
• geomembranes,which are relatively impermeable sheets of polymeric formulations
can be used as a barrier to liquids, gases and/or vapors;
• geocomposites, which consist of two or more geosynthetics, can be used for separation,filtration or drainage;
