Laying=“ http://www.lianyisuliao.com/ Geomembraneis an important part of the anti-seepage system. The quality of the geomembrane itself and the welding construction quality directly affect the success or failure of the entire anti-seepage project. Geomembrane can not only reduce the possibility of geomembrane damage, but also ensure the anti-seepage period of the landfill. The characteristics of geomembrane analysis and testing are: obvious temperature effect, weak humidity sensitivity of polyolefin geomembranes, and different humidity sensitivity of other types of geomembranes with different moisture absorption properties. The time effect is obvious - creep and relaxation, and deformation speed has a significant impact.
