　　The way the HDPE Geomembrane is seamed and installed also matters a great deal. International standards provide guidelines on the seaming methods and the quality of the seams. There are different seaming techniques, such as hot wedge welding and extrusion welding. The standards specify the parameters for these welding methods, including the temperature, pressure, and speed.

　　Proper installation is essential for the performance of the geomembrane. The ISO and ASTM standards offer guidance on site preparation, such as the smoothness of the sub - grade, and the installation process itself. This includes how to handle the geomembrane sheets during installation to avoid damage, and how to ensure proper overlap and alignment of the sheets.
