Geomembrane

 ■ Function

Antiseepage and seperation

 ■ Usage

· Prevent leadage disposal in waste burying field or waste water or waste dregs disposing field.

· River bank, lake dam, mine remainings, reservior, tunnel, liquid storage pool(pit, mine)

· Preventing leakage in subway, basement, tunnel, hole.

· Anti-solt leakage in roadbed and other groundsill.

· The plane direction  laying of dam,  the vertical direction  laying  for groundsill, used  in  the construction  fence and waste material field.

· Used in seawater or freshwater feed field.

· Used in groundsill of road, highway, railway and waterproof layer of swelling clay and wet collapsed loess.

· Preventing leakage on rooftop.
