Composite Geomembrane Introduction
The geotextiles provide increased resistance to puncture, tear propagation, and friction related to sliding, as well as providing tensile strength in and of themselves.
The geomembrane provides waterproofing and reinforcement functions.
Its performance can meet or exceed our national standard GB/T17642.
Features and benifits
♦ Good waterproofing property
♦ High anti-puncture strength
♦ Large friction coefficient
♦ Aging resistance
♦ Strong adaptability to environment temperature
♦ Low cost and easy installation
Composite geomembranes are divided into two categories according to the length of composite fibers：
Long fiber composite geomembrane
Short fiber composite geomembrane
Sort by compound：
One geotextile and one film
Two geotextiles and one film
Q:What are the specifications of composite geomembrane?
A:1. One geotextile and one geomembrane — geotextile unit weight: 150gsm–400gsm, geomembrane thickness: 0.25-0.8mm.
2. Geomembrane with both sides of geotextiles — geotextile unit weight: 100gsm–400gsm, geomembrane thickness: 0.2-0.8mm.
