geocomposite/compound geomembrane/geotextile membrane

1. Composite geomembrane uses earthwork fabric to replace particle material as geomembrane protection layer so as to protect geomembrane anti-seepage layer from damage and to reduce grading requirement of underlying layer particle diameter, and can play the function of drainage.
2. Composite geomembrane has large friction factor, and can prevent coverage layer from sliding. Comparing with simple HDPE film, non-woven cloth in composite geomembrane has large friction factor, and composite earthwork film can make slope ratio increase, and reduce floor area.
3. Composite geomembrane has high mechanic strengths such as tension, tearing, breaking and puncture resistance.
4. Composite geomembrane has certain deformation quantity, has quick transfer and spread of stress caused by uneven defect of underlying layer, and has strong stress capacity.
5. Pore pressure and uplift pressure on contact surface between composite geomembrane and earth body are easy to spread.
6. Composite geomembrane has certain heat preservation, which reduces damage on geomembrane by frozen expansion of earth body so as to reduce deformation of earth body.

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.
6. Waterproof layer of roadbed, swelled ground and collapsible loess of highroad, expressway and railway.
