Dam Liner Compound LDPE Geo-membrane

Name

Compound Geomembrane

Description

Compound geomembrane is a waterproof material formed with the fusing of non woven fabric and 

Polyethylene membrane. Compound geomembrane may be of two types - one side non woven fabric 

and one side PE membrane and two sides non woven fabric with PE membrane in between.

Geomembrane Material:LDPE geomembrane

Geotextile Material:PP or PET staple nonwoven geotextile

                PET filament spunbond nonwoven geotextile

Features

1.Excellent tensile strength

2. High bursting resistance

3.Aging resistance

4.Anti-corrosion

5.Long temperature range and life span

Application

As compound geomembranes have good plane drainage, excellent seepage resistance and high mechanic strengths such as tension, tearing, breaking and puncture resistance.

1. River dike, lank bank, tailing bank, reservoir area, water channel and liquid tank (pit).
2. Anti-seepage blocking of subway, basement and tunnel
3. Waterlogging and anti-seepage of roadbed and other foundations.
4. Horizontal anti-seepage laying of dike and bank, vertical anti-seepage layer of foundation, construction cofferdam and waste material yard.
5. Seawater and freshwater cultivation farm.
