Description
Membranes have been utilized in landfill operations for decades, but the choice of membrane and its method of employment can have far-reaching effects on the stability and safety of landfill sites
Geomembranes, predominantly high-density polyethylene (HDPE), have been used as bottom liners in landfills for almost 30 years. They have also been used as caps and, more recently, for floating covers on leachate ponds. Generally they have performed extremely well but, not unexpectedly, there have been a few exceptions that have guided us in developing even better systems.
They are widely used in Tank Liners, Aquaculture, Mining, Water and Solid Waste Management, Fluid Conveyance and Containment, Ash Ponds, Soil Protection and Stabilization, Land Fill Closures, Ponds and Reservoirs, Irrigation Canals, Waste Containment, and many other applications.
