　　During construction, the sandstone, fabric, and other building materials surrounding the drainage layer have a significant impact on the hydraulic conductivity of the composite geomembrane. According to years of practice, the thickness of HDPE geomembrane should not be less than 0.25mm. If it is too thin, it may produce pores and be easily damaged during construction, resulting in poor anti-seepage effect. During the construction of geomembrane, special attention should be paid to ensure that the laying is not too tight, wrinkles are not allowed, and the splicing is firm. We must strictly follow the technical specifications for construction, and ensure the quality of five aspects including laying, splicing, inspection, and backfilling. The effect of using artificial hot welding is better than that of adhesive, but the manual construction cost is slightly higher, suitable for some large-scale anti-seepage projects, generally referring to projects with a quantity of more than 5000 square meters; For a small amount of anti-seepage, such as 1000-2000 square meters, special adhesive can be used for construction to control costs, which will be relatively more acceptable. Of course, if you value the seams and ignore the cost, then use manual labor.
