Geomembrane can be divided into PVC geomembrane, HDPE geomembrane, LDPE geomembrane, EVA geomembrane.

 They are mainly used in the subgrade anti-seepage of the roads, railways, etc, and also applied to dealing with the leakage of  landfills,dams,drains,tunnels and fish farms.

Application:

*River bank:

Road along the river and road covered with water should be used complex earth film with reinforcing bars to protect the slope along the river.

*Road in loess area:

In designing ,drainage should be paid more attention,then take the measurements to head off and separate. Set up swash-proof and leakage proof.

*Long-time ice road:

Drainage system should be established far away from the boot of the slope to prevent the water flow and leakage from influencing the changes of the ice-road upper limit.Removing the underneath water will take away the underneath water which can probably from drumlin.When granule earth is used to build the road dike, the foot of the road dike should be set up with thin water partition to prevent the underneath water from gatherung up to the road dike.

*Road  in swelling earth area:

For the road part of strong swelling earth and medium swelling earth in high way, the road should be designed as that kind of water proof, heat preservention,and wind proof.No leakage floor in the central separation area.

*Drainage,water proof and leakage proof in salty area:

To prevent the ice swelling ,salt swelling in salty area, thin water partition should be set up,40-50 cm thick.Anti -filtration should be established on the top of it and at the foot of it;fabric of leakage proof can also be used such as complex earth film and complex earth film with reinforcing bar.
