Product Details

Geomembrane(smooth)Product Introduction:

Composite geomembrane is a kind of anti-seepage geosynthetic material taking non-woven geotextile as base material, and HDPE geomembrane as the membrane material. Its waterproof feature mainly depends on the characteristic of geomembrane.

Plastic membrane used in anti-seepage projects at home and abroad mainly include PVC,PE EVA, and ECB applied in tunnel, which are all polymer chemistry flexible material with small rate, strong extension, high deformity, corrosion resistance, low temperature resistance and good ability of antifreezing. Its main mechanism is separating leakage channel of earth dam with the waterproof feature of plastic membrane, bearing water pressure and adapting deformation of dam with large tensile strength and elongation; While non-woven geotextile is a polymer short-fiber chemical material, and it is formed through needle-puncturing or thermal pasting. and it has higher tensile strength and elongation.

Product Features：

Geomembrane is a waterproof separating material taking high macro-molecular polymer as basic raw material. It is mainly divided into LDPE geomembrane,HDPE geomembrane and EVA geomembrane.

1. Width, thickness and specification are complete;

2. Have good environment stress crack resistance and good chemical resistance;

3. Have good chemical resistance;

4. Have good using temperature range and longer lifelong.

5.It is applied in landfill, tail storage site, tunnel anti-seepage, dike seepage and subway project, etc.

Product Application：

It is mainly applied in impermeable projects such as channel, sewage treatment tank, dock engineering, embankment reservoir, dam, subway, landfill, etc.
