Reinforced Polypropylene (RPP) geomembrane is a heat-weldable polyester reinforced sheet designed for liners in potable and industrial water containment applications. The membrane is specifically formulated for long-term use in buried or exposed geomembrane applications. The membrane is based on a UV-stabilized polypropylene copolymer that does not require either polymeric or liquid plasticizers to maintain flexibility.
