A smooth geomembrane is a high-performance, impermeable synthetic liner made from high-density polyethylene (HDPE), linear low-density polyethylene (LLDPE), or polyvinyl chloride (PVC). Characterized by its flat, non-textured surface, it provides an excellent barrier against liquid and gas migration. Widely used in containment, lining, and waterproofing applications, smooth geomembranes are prized for their low permeability, flexibility, and long-term durability in both exposed and buried environments.
