Geomembrane or Composite Geomembrane--The Important Things that You Must Know
Geomembrane or Composite Geomembrane--The Important Things that You Must Know
Many friends may not know what color the impermeable geomembrane is. At present, the market is mainly black, but also white and blue. The color is not important to the impermeable geomembrane. The most important thing is the impermeable geomembrane. The raw materials and production process of the membrane, whether the manufactured anti-seepage geomembrane is anti-seepage, anti-leakage, anti-corrosion, anti-acid and alkali, strength coefficient, adhesion and other indicators pass the test.
The most commonly used impermeable membranes are mainly the following two categories:
HDPE geomembrane
HDPE geomembrane is light, and easy to hot-melt bonding, good splicing. The thickness is generally 0.4-0.8mm. When laying the anti-seepage geomembrane, the foundation treatment must be careful, otherwise the membrane will be broken and damaged.
Composite geomembrane
Because the composite geomembrane is a composite of geotextile and geomembrane, it has greater tensile strength than the anti-seepage membrane, and the amount of expansion and contraction is smaller than that of the anti-seepage HDPE geomembrane. If there are splicing places in the anti-seepage project of the pool, it is easy to leak if the welding treatment is not good. Generally, 500-900 grams of composite geomembrane is used.
At present, composite geomembrane is selected for anti-seepage projects, which is often referred to as one cloth and one geomembrane or two cloth and one geomembrane. The construction is convenient and can more effectively protect the geomembrane from damage. At the same time, the above geotextile is more conducive to strengthening and strengthening toughness. , The service life is long-term, the service life of our composite geomembrane reaches more than 50 years.
