In view of the fact that some synthetic geomembrane field observations have certain anti-aging capabilities in engineering applications, some countries have made certain provisions for their service life in some documents, such as the former Soviet Union BCH07-74 "Earth-rock dam applications. Polyethylene impervious structure instructions, the provisions of polyethylene geomembrane can be used in buildings with a life of not more than 50 years.
The conclusion in the article “Long-term properties of polypropylene composite geomembranous geosynthetics†published by Linz, Austria, states: 'The experience of field application of polypropylene for more than 15 years shows that they have high chemical and biological stability; fabrics The greatest damage is in construction; there are no major changes after laying; ... stability over 100 years can be expected.
