XR® Geomembranes vs. HDPE (High Density Polyethylene)
Geomembrane Competitive Comparison
Advantages of 30 mil XR Geomembranes vs 60 mil HDPE: Thicker is Not Better.
- Membrane Strength:
XR-5® geomembranes provide over 300% higher puncture strength vs twice as thick 60 mil HDPE and over 200% better tensile strength - Environmental Stress Cracking:
This is a material inherent problem identified by the EPA. XR-5 geomembranes are not subject to ESC. - Flexibility for Prefabrication and Ease of Installation:
Prefabrication of XR-5 geomembranes allows for improved liner integrity and significantly reduces the number of field seams. HDPE is too rigid to prefab. Therefore, all seams are field seams which translates into longer installation time, higher installation costs and lower membrane integrity. - Thermal Expansion/Contraction:
HDPE suffers from extreme thermal expansion and contraction. Contraction is 22 times lower with XR-5 geomembranes, eliminating the need for design consideration of thermal effects.
