Differences Between XR Geomembranes and Polypropylene Liners
XR Geomembranes are built to outlast and outperform competing products. Engineered for the very toughest applications and environments, XR Geomembranes set the industry standard for geomembrane strength, durability, and performance.
Compared to polypropylene liners, XR Geomembranes offer better tensile strength, puncture resistance, blocking resistance, and more. See the chart below to learn how a 30 mil XR-5® stacks up against a 36 and 45 mil polypropylene geomembrane.
