The use of geotextile must be buried: the covering thickness should not be less than 30cm. The refurbished anti-seepage system should consist of cushion layer, anti-seepage layer, transition layer and protective layer. The soil should be solid to avoid uneven settlement and cracks. Sod and tree roots within the anti-seepage area should be removed.
What are the precautions for geotextile construction?
(1) The use of geotextile must be buried: the covering thickness should not be less than 30cm.
(2) The refurbished anti-seepage system should consist of cushion layer, anti-seepage layer, transition layer and protective layer.
(3) The soil should be solid to avoid uneven subsidence, cracks, and turf and tree roots within the anti-seepage area should be removed. Pave the sand or clay with a small particle size as a protective layer on the contact surface with the membrane.
(4) When laying, the geomembrane should not be stretched too tightly. It is better to be corrugated when the two ends are buried in the soil, especially when anchored with rigid materials, there should be a certain amount of expansion and contraction.
(5) During the construction, avoid stones and heavy objects directly on the geomembrane. The editor of Shandong Lianxiang recommends that the construction be carried out while laying the membrane and covering the protective layer.
