Soil Liner
Soil liner
One of the requirements of modern sanitary landfills is that a soil liner be placed on top of the existing soil. Liners are needed to prevent the penetration of landfill leachate into the soil. Without a liner, leachate could move through the soil and contaminate the groundwater . Soil liners can be made of clay, plastic, rubber , blacktop, or concrete.
