Differences Between XR Geomembranes and Polyethylene Liners
Working on a geomembrane project and not sure which liner is best suited for your application? Consider XR Geomembranes. With a broad range of chemical resistance and physical properties, XR Geomembranes help protect the environment through primary and secondary containment, have superior seam strength, and more.
Compared to competitive products, including chlorosulfonated polyethylene (CSPE), XR Geomembranes are built to outlast and outperform, setting the industry standard for strength, durability, and performance. See the chart below to learn how a 30 mil XR-5® stacks up against a 36 and 45 mil polyethylene liners.
