Sanitary Landfills
Today’s sanitary landfill designs require a range of geosynthetic products to maximize design efficiency, integrity and performance while minimizing overall cost. For environmental protection, the essential landfill component is the primary liner which contains hazardous leachates and protects valuable groundwater resources. Geomembranes can be utilized to conform this impervious layer due to their proven performance as a cost efficient replacement to conventional clay and concrete lining systems, providing many benefits such as durability in exposed conditions, resistance to a broad range of chemical substances, and rapid installation.

Frecuently, landfills are designed with steep slopes to increase its storage capacity. These steep slopes present problems for smooth liners because cover soil may not stay in place and, with overburden, the liner itself can slip down the slope and increase stress on seems and the sheet itself. Textured geomembranes are utilized for this application, which provide frictional interaction with the soil in order to stabilize loads.

Completely filled landfills have to be covered with a watertight liner. A major long term concern when employing a landfill cover is differential settlement caused by decaying and shifting waste. The cover must facilitate deformation caused by differential settlement without failure of the containment. To meet this requirement, highly flexible geomembranes are available specifically designed with proven performance on landfill cover applications.
