The environmental geomembrane factory price strictly produced according to the America standard GRI GM-13, and test by ASTM method. So, it is a high-grade virgin HDPE environmental geomembrane for sale, with very good UV resistance, aging resistance, corrosion resistance, and long service time.
1. Environmental geomembrane produced by the environmental geomembrane manufacturers has High physical and mechanical indexes: the tensile strength can reach more than 27MPa; Elongation at break can reach more than 800 percent; the right-angle tear strength can reach more than 150N/mm.
2. Environmental geomembrane has Good chemical stability: wholesale environmental geomembrane factory price produced by the environmental geomembrane manufacturers (wholesale environmental geomembrane) has excellent chemical stability, widely used in sewage treatment, chemical reaction tank, and landfill. Resistance to high and low temperature, asphalt, oil and tar, acid, alkali, salt and more than 80 kinds of a strong acid and alkali chemical medium corrosion.
3. Environmental geomembrane has High anti-seepage coefficient: Environmental geomembrane for sale (environmental geomembrane factory price) has an incomparable anti-seepage effect compared with ordinary waterproof materials, and the water vapor seepage system K<=1.0*10-13g. Cm /c cm2.s. a.
4. Environmental geomembrane produced by the environmental geomembrane manufacturers is friendly to the environment. It uses environmental protection material, the impervious principle is a common physics change, do not produce any harmful material, it is the best choice of environmental protection, breed, and drinkable pool.

Cautions of The Installation Environmental Geomembrane
Please do not drag the HDPE liner HDPE geomembrane in the transportation, and avoid stabbing by sharp objects.
1. From the bottom to the high extension, do not pull too tight, should leave 1.50% of the residual, in case of local subsidence stretch. Considering the actual situation of this project, the slope is laid from top to bottom.
2. The longitudinal joints of adjacent two pieces shall not be in a horizontal line and shall stagger each other for more than 1m;
3. The longitudinal joint shall be more than 1.5m away from the dam foot and bend foot and shall be set on the plane;
4. Install the HDPE liner on the Slope first, then install the bottom.
5. When the slope is laid, the film-spreading direction should be basically parallel to the maximum slope line.
6. The temperature should generally be more than 5 degrees Celsius, HDPE liner HDPE geomembrane should be tense at low temperature, HDPE liner should be loose at high temperature.
7. The wind is below grade 4 for work condition.
8. When the temperature is too low, the construction should not be carried out in windy and sleet weather above grade 4.
9. In windy weather, when the wind influences the construction of HDPE liner, the HDPE liner to be welded shall be pressed firmly with sandbags.
