Geomembrane anti-seepage film technical requirements are as follows
1. Before the laying of dam liner/fishing farm/shrimp liner Hdpe geomembrane, the corresponding certificate of conformity acceptance should be obtained from the civil engineering project.
2. Before the HDPE geomembrane is cut, the relevant dimensions should be accurately measured, and then cut according to the actual size. Generally, it should not be cut according to the size of the figure. It should be numbered one by one and recorded in a special form.
3. When laying HDPE geomembrane, the weld seam should be the least, and under the premise of ensuring the quality, the raw materials should be saved as much as possible, and the quality can be easily ensured.
4. The geotextile lap width of the joint between the film and the film is generally not less than 10 cm, and the weld alignment direction is usually parallel to the maximum slope, that is, arranged along the slope direction.
