Just as federal and state regulations detail every aspect of landfill location, construction and operation, they now detail every aspect of its closure design. A typical MSW landfill cap, from the bottom up, consists of a gas-venting layer, a low-permeability barrier layer (soil, a geosynthetic clay liner and/or a geomembrane), a barrier protection layer and a vegetable soil layer.
Closure requirements are critical for the post closure life cycle of a landfill as many landfills do not have synthetic membrane linings to prevent the filtration of leachate into the groundwater. Consequently the formation of leachate within a landfill cell must be prevented at all costs.
GeoCHEM's containment linings fulfill this need. Liners are provided in large factory fabricated panels to reduce field seaming requirements and installation costs. Reliable, durable, fully homogenous factory and field seams.
Excellent puncture and impact resistance to resist mechanical damage during installation and earth covering operations.
A specifying engineer or project owner can be assured of the long-term serviceability of GeoCHEM's Landfill Capping Geomembranes..
