Geomembrane film to buy underground for many years, that is to maintain anti-leakage function, or degradation of the time range, thank you
Theoretically 30 years to 50 years is no problem, I am the production of geotechnical materials
Buried at least a few decades is not a problem
Geomembrane life is mainly by the membrane is lost seepage barrier depending on the role, according to national standards, working conditions in the water under the conditions of up to 40 to 50 years, working conditions in the sewage conditions for 30 to 40 years. The general life of more than 50 years, geomembrane construction Notes: 1, the construction staff must wear non-staple or rubber shoes, to prohibit any trampling on the geomembrane. 2, after the film should be timely protective layer construction, to prevent heat shrinkage caused by geomembrane deformation and ultraviolet radiation caused by geomembrane aging. 3, prohibit contact with polyolefins can cause changes in chemical properties, so as not to permanent deformation of geomembrane. 4, the machine must not directly crush the surface of the geomembrane, the requirements of the geomembrane meet, the geomembrane life of the secret will gradually increase. Rigorous construction, can be a composite geomembrane users save time, effort, provincial costs, to achieve the best use of geomembrane state and effect.
