Overview
Function & Application
Technical Para
Production & Package
BPM composite geomembrane is made of geotextile (base fabric can be filament or short fiber needle punched geotextile ,woven geotextile )and high polymer by calendering and hot-melt technology .
It remains the mechanical properties of base fabric and uniformity of film which improve the impermeability.
Embossed processing on the film strengthen its friction coefficient,stability and easy for installation .
Function: Impermeable, reinforcement, protection .
 
Application: Applied to waterproofing lining of dam or canal and anti-pollution of waste plant .
