High Density Polyethylene Geomembrane Properties

The modern sanitary landfill is a highly engineered containment structure, designed to isolate solid waste from the surrounding environment for decades. Central to this design is the impermeable geomembrane, a synthetic polymeric liner that serves as the primary hydraulic barrier. This document details the critical role of geomembranes, particularly HDPE liner systems, in landfill engineering, encompassing material science, system integration, and construction protocols.
