Geomembranes are designed to be impermeable, meaning water cannot typically pass through a geomembrane. Typically made from materials like high-density polyethylene (HDPE), polyvinyl chloride (PVC), or ethylene propylene diene monomer (EPDM), geomembranes have a dense molecular structure that prevents water from passing through.
This impermeability is crucial in applications such as landfill liners, pond liners, and containment systems, where the goal is to prevent the migration of liquids and contaminants into the surrounding environment.
