Questions about the use time of geomembrane, it mainly depend on which kinds of material geomembrane have used.For example, the material of geomembranes use are generally part of the plastic film.So the main factor in the use of time is this layer of film is the performance of water seepage.
For example, in some countries in Europe and the United States, when they are in the production of geomembrane, generally will use a relatively high thickness, and has added a stabilizer polyethylene film, so the film can be used under normal conditions, the time can be long Up to 100 years, this is not a strange thing.However, if it is in the harsh environment, such as long-term use in the sewage environment, then the use of time may be shortened to several decades time.For some of the better quality of the geomembrane longer use, has been widely applied to some of the dam seepage project, because their service life is more long.
In China's general geomembrane used in the life of plastic film after the experiment proved that the use of life can reach more than 50 years, and the relatively high chemical stability.If you can control the construction process at the time of the whole process, after laying basically will not affect the geomembrane, so the late use of quality can also have higher protection.
