Overview
Function & Application
Technical Para
Production & Package
BPM single or souble textured polyethylene geomembrane has a rough surface which improve the friction coefficient .
It fits more suitable for steep slope and vertical engineering design work which maximize the effective volume of geomembrane .
Compared with smooth liner ,it has better UV and puncture resistance .
Function: Textured geomembrane has the impermeable, antifouling, antiskid function ,convenient for construction.
Application: It’s mainly applied to landfill and mining .
