Laminated nonwoven fabric for special package,waterproof nonwovens
This compound geomembrane is compounded by more than two kinds of materials, including non woven geotextiles (or fiber-glass net) and macromolecule materials (such as PE membrane (HDPE or LDPE), EVA membrane).
We also can manufacture this compound geomembrane according to customers' requirements.
2,Excellent environmental stress resistant cracking performance;
3,Excellent performance of chemical erosion resistance;
4,Big scope of application temperature and long service life
As client's requirment product it.
the min mass of nonwovens: 20gsm, the min mass of membrane:20gms or0.02mm
The use of composite geomembrane
1.The river bank, lake dam, tailings dam, waste water dam and reservoir area, channels, build liquid pool (pit, Kuang).
2.subways, basements and tunnels, the tunnel impermeable lining.
3.the roadbed and other foundation saline seepage.Embankment, the dam of the level of impervious blanket, the vertical impermeable layer of foundation, construction of the cofferdam, the scrap yard.Seawater, freshwater farms.Roads, railways, high-speed highway of roadbed; waterproof layer of swelling soil and collapsible loess.
