Introduction

Composite Geomembrane are made of polyester staple fiber geotextile,polypropylene staple fiber and polyester continuous filament geotextile as the base material and high-density polyethylene as the geomembrane material by composite. There are one geotextile and one geomembrane,two geotextiles and one geomembrane,two geomembranes and one geotextile,multi-geotextiles and multi-geomembrane etc.The product max width 6m,length 50m-100m,u can customize it.

Properties Of Composite Geomembrane

 *High tensile strength and good elongation

*Resistant to acid and alkali corrosion

*Good durability

*High mechanical index

*High puncture resistance and high friction coefficient

*Good aging resistance

*Excellent anti-drainage performance

Advantages Of Composite Geomembrane

*It has good plane drainage and excellent anti-seepage characteristics

*It has the characteristics of high tensile trength, good elongation performance, large friction coefficient, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance and so on

*It has a certain heat preservation effect and reduces the damage of soil frost heave to geomembrane

*Stable low-temperature embrittlement resistance

*Excellent Chemical and UV Resistance

*Easy to install and save cost

 Application Of Composite Geomembrane

*Landfill, sewage or waste disposal seepage prevention

*River dike, lake dam, tailings dam, sewage dam and reservoir area, channel, reservoir

*Subway, basement and tunnel, tunnel anti-seepage lining

*Subgrade and other foundation salt seepage prevention

*Embankment, horizontal anti-seepage blanket in front of dam, vertical anti-seepage layer of foundation, construction cofferdam, waste yard

Seawater, freshwater farms

*Roads, highways, railway foundations, expansive soil and collapsible loess waterproof layer

*Roof seepage prevention

*Airport runway apron,water conservancy project etc
