RPE GEOMEMBRANES

 

Reinforced Polyethylene (RPE®) can be used as an economical geomembrane material. Common uses of RPE®'s are canal liners, drilling sump liners, soil remediation liners, tailings dam liners, and interim landfill caps. RPE®'s have UV resistance for short term exposed use, are flexible in extremely low temperatures, and have very good chemical resistance. Reinforced Polyethylenes (RPE) are manufactured from a very chemical-resistant, Linear Low Density Polyethylene with excellent cold crack performance. It is available in various colors.

​

RPE®’s are most commonly used for seepage control in non-hazardous applications. In canal liners and water reservoirs a backfilled RPE® liner provides permanent seepage control. In a carefully prepared site on sandy soils RPE® can provide geomembrane level containment, however placement and backfilling of the material needs to be done carefully. RPE is made up of woven, prestressed tapes made from HDPE. The HDPE tapes are coated with a film of LDPE which makes the liner impermeable to water.

​

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 a facility. It is available in 0,76 mm, 0,91 mm, and 1,14 mm thicknesses. RPE can be prefabricated in panels of up to 3.000 sqm. 

In the field DGS Fabrics installs RPE using heat fusion welding equipment, operated by a trained technician, which offers a high quality lining system.
