Textured surface
The textured surface provides increased interface friction for containment systems where resistance to sliding is an important design consideration.
HDPE Textured Geomembrane (GH-2T1 / GH-2T2)
Textured high-density polyethylene geomembrane for containment systems requiring increased interface friction.
GH-2T1 and GH-2T2 are textured HDPE geomembranes designed for landfill, mining and environmental containment applications where both seepage control and increased surface friction are required.
Product Overview
0104
GH-2T1 and GH-2T2 are textured high-density polyethylene geomembranes used in containment and seepage-control systems where increased surface friction is required. The textured surface provides a higher-friction interface for applications where resistance to sliding is an important design consideration.
Typical uses include municipal environmental projects, landfill caps and liners, mining heap leach pads, wastewater treatment lagoons, secondary containment, solid-waste landfills and hazardous-waste landfills.
