RPP Geomembranes - (Reinforced Polypropylene)

An extremely durable product, RPP is designed to be left exposed and is reinforced with nylon scrim to provide excellent dimensional stability and superior toughness. RPP is used widely in exposed Wastewater Treatment ponds, as landfill cover lining, in floating covers and baffle curtains, in lagoon lining, and as a liner for ponds, lakes and water features.

Description
Reinforced Polypropylenes (RPP) are manufactured by an extrusion process (or calandering) into plies that are usually combined over a reinforcing polyester scrim fabric during the manufacturing process. Scrims are fully contained within the two layers of polypropylene to eliminate wicking.

RPP has superior UV and Ozone resistance, excellent chemical resistance and is available in various colors (colors are a special order with a minimum sf purchase) for an aesthetically pleasing appearance.

  RPP is also becoming increasingly popular in the golf construction market. It is used primarily on lakes where there is limited cover material or the slope design is too steep to hold a cover soil.
