RPE - Reinforced Polyethylene

An extremely durable liner product, RPE is UV stable and is designed to be left exposed. It is a proven solution mostly due to its excellent puncture resistance. RPE can be used in exposed wastewater treatment plants, agricultural ponds, oil & gas temporary evaporation ponds, aquaponics, golf course pods, irrigation reservoirs and more.

Reinforced Polyethylenes (RPE) are manufactured from a very chemical-resistant, Linear Low Density Polyethylene with excellent cold crack performance. RPE Liner is formulated with thermal and UV stabilizers to ensure long life and excellent chemical resistance. It is available in various colors (colors are available after consultation as special order items with a minimum sf purchase) for an aesthetically pleasing appearance.

Product Warranty
Warranties range from 5-20 years and are subject to thickness, application, and regional factors.

RPE is heat welded under controlled conditions into panels at the CLI fabrication facility. It is available in 30 mil, 36 mil, and 45 mil thicknesses. CLI fabricates RPE in panels of up to 30,000 sf.

CLI installs RPE using heat fusion welding equipment, operated by a trained technician, which offers a high quality lining system.
