How long is the service life of geomembranes

Geomembrane is buried in the ground, can only let nature take its course, geomembrane is difficult to degrade naturally, if the project renovation or for other purposes, can only be cleaned up, some of the very troublesome.

Geomembrane service life depends to a large extent on the use of the environment, such as buried in the ground and exposed to use, life is very different, how to use to extend its service life?

Most people have this question about the service life of geomembrane, how many years can it be used in the end? If a number of years after the damage we should how to deal with? The above is the geomembrane service life of a few years for you to organize the relevant information.

Geomembrane is buried in the ground, can only let nature take its course, geomembrane is difficult to degrade naturally, if the project renovation or for other purposes, can only be cleaned up, some of the very troublesome. However, geomembrane has no damage to the environment. Geomembrane's service life, mainly by the plastic film is impermeable waterproof role depends on

HDPE geomembrane full name "high-density polyethylene membrane", with excellent resistance to environmental stress cracking performance, low temperature, aging resistance, corrosion resistance, as well as a wide range of temperatures (-60 - +60) and a long service life (50 years). Geomembrane has an ordinary waterproof material can not be compared to the seepage effect, has a strong tensile mechanical, and excellent elasticity and deformation, suitable for deformation of a relatively large number of short base, and excellent chemical stability, is used in sewage disposal, chemical reaction pools, waste landfills and so on.

In view of the composite geomembrane part of the field observation results of synthetic materials in engineering applications with aging resistance, so some of the documents on the use of its life for a more lenient provisions, such as BCH07-74 "earth and rock dams, application of polyethylene seepage control structure instructions" in the provisions of the polyethylene geomembrane can be used in the use of the life of the building is not more than 50 years. The conclusion of the article 'Long-term properties of polypropylene composite geomembrane geosynthetics' published by Linz, Austria, states: 'More than 15 years of field application experience with polypropylene has shown that they are chemically and biologically stable; damage to the fabric is during construction; there are no major changes after laying; ...... More than 100 years of stability can be expected.

② Outstanding resistance to stress cracking (resistance to environmental stress cracking).

③Lower permeability.

① Better chemical resistance (corrosion resistance).

⑤ stable resistance to low temperature embrittlement; ⑤ better UV resistance (corrosion resistance); ⑤ stable resistance to low temperature embrittlement; and

(iv) Better UV resistance.

Using more than 80% of new material production of high-quality HDPE geomembrane, product quality up to the national standard GB/T17643-2011GH-2S/city CJ/T234-2006 standard, the standard HDPE geomembrane also has a high resistance to acid and alkali, corrosion resistance, can be used for sewage treatment plant seepage control, landfill seepage control, tailings disposal site seepage control project, generally using the More than 80% of new material production of high-quality HDPE geomembrane service life in the underground can reach more than 50 years, the ground service life can also reach more than 10 years.

Using new material production of high quality HDPE geomembrane, product quality can reach the American standard GRIGM-13 standard, the standard HDPE geomembrane has high acid and alkali resistance, corrosion resistance, can be used in a variety of engineering seepage control, general use of new material production of high quality HDPE geomembrane service life in the underground can reach more than 100 years, the ground service life can also reach more than 20 years.
