In view of the on-site observation results of some composite geomembranes, synthetic materials have certain anti-aging capabilities in engineering applications, so some documents in some countries The service life is relatively lenient. For example, the former Soviet Union's "Instructions for the Application of Polyethylene Anti-seepage Structures in Earth-rock Dams" stipulates that polyethylene geomembranes can be used in buildings with a service life of no more than 10 years. The conclusions in the article Long-term Behavior of Polypropylene Composite Geomembranes Geosynthetics published by Linz Austria Company write that more than 20 years of field application experience with polypropylene has shown that their chemical and biological stability is high. The greatest damage to the fabric is during construction. No major changes can be expected after the mid-laying period and the stability will last more than 20 years.
