What should we pay attention to when constructing composite geomembrane?
May 13,2024
1. Embedded type must be used: the covering thickness should not be less than 30cm.
2. The renovation anti-seepage system should consist of: cushion layer, anti-seepage layer, transition layer and protective layer.
3. The soil must be solid to avoid uneven subsidence and cracks, and turf and tree roots within the anti-seepage range must be removed. Sand or clay with small particle size is laid on the contact surface with the membrane as a protective layer.
4. When laying, do not pull the geomembrane too tightly. It is better to have the parts buried in the soil at both ends in a corrugated shape. Especially when anchored with rigid materials, a certain amount of expansion and contraction should be left.
5. During construction, stones and heavy objects should be avoided from hitting the geomembrane directly, and the protective layer should be covered while laying the membrane.
