Please don't drag the HDPE liner HDPE geomembrane within the transportation, and avoid stabbing by sharp objects.
1. From rock bottom to the high extension, don't pull too tight, should leave 1.50% of the residual, just in case of local subsidence stretch. Considering the particular situation of this project, the slope is laid from top to bottom.
2. The longitudinal joints of adjacent two pieces shall not be during a horizontal line and shall stagger one another for quite 1m;
3. The longitudinal joint shall be quite 1.5m faraway from the dam foot and bend foot and shall assail the plane;
4. Install the HDPE liner on the Slope first, then install rock bottom.
5. When the slope is laid, the film-spreading direction should be basically parallel to the utmost slope line.
6. The temperature should generally be quite 5 degrees Celsius, HDPE liner
environmental geomembrane manufacturers should be tense at coldness, HDPE liner should be loose at heat.
7. The wind is below grade 4 for work conditions.
8. When the temperature is just too low, the development shouldn't be administered in windy and sleet weather above grade 4.
9. In windy weather, when the wind influences the development of HDPE liner, the HDPE liner to be welded shall be pressed firmly with sandbags.
