Our company is a famous composite geomembrane supplier in China. Our brand, YINGFAN, is quite well-known in the geosynthetic industry in our country. Many domestic and overseas customers purchase our composite geomembrane with competitive price and reliable service.

Composite Geomembrane Introduction

Our Composite Geomembrane (Geotextile-Geomembrane Composites) is produced by thermally bonding a nonwoven geotextile layer to a PE geomembrane sheet. It combines the advantages and functions of both geotextile and geomembrane.

The geotextile layer improves puncture resistance, tear resistance, sliding friction performance and tensile strength.

The geomembrane layer provides waterproofing and anti-seepage reinforcement.

Its performance can meet or exceed Chinese national standard GB/T17642.

Features and Benefits

• Good waterproofing & anti-seepage property

• High puncture resistance

• Large friction coefficient

• Excellent aging resistance

• Strong adaptability to ambient temperature

• Cost-effective and easy installation
