Abstract
A friction enhancing material is applied to at least one surface of the geosynthetic clay liner. The placement of friction enhancing material on the surface of the liner that engages a slope or embankment of a landfill helps the liner maintain its position during and after installation. The improved frictional contact between the liner and the slope or embankment permits use of bentonite liners on steeper slopes or embankments and therefore enables more efficient construction of landfills. The friction enhancement material may also be applied to the surface to improve contact between the upper surface of the geosynthetic clay liner and the cover soil. The friction enhancement material may be high density polyethylene, EVA, rubbers and other polymeric materials.
