For those who have experience in geomembrane construction, it is necessary to pay attention to certain matters of GCL geosynthetic clay liner factory price and product laying. Generally speaking, the laying of geomembrane is divided into two steps: plane laying and facade laying. After the acceptance of the geomembrane, the surface is laid first, and then the elevation is laid in the order from east to west and from bottom to top. Someone asked how the tightness of the geomembrane should be arranged when laying.

What are the tightness requirements for dimple drainage board for sale laying? How to place it?

Laying should be carried out in a dry and warm climate to facilitate splicing and avoid stress concentration. When laying, the tightness of the geomembrane should be controlled at about 1.5%. After paving, the geomembrane should be flattened and pulled away in time to make the geomembrane consistent with the useful surface without raised folds.

During construction, the construction personnel must wear flat shoes or soft rubber shoes. It is strictly forbidden to step on the storage and drainage sheet made in China through spikes. If the geomembrane is damaged during construction, it should be repaired in time. Since polyethylene is a petroleum product, it can adsorb other petroleum products. Like a sponge, the thickness of the wood will increase and become more flexible, but there will be no pores or mesopores. This adsorption is different from sponges and is not immediate.

The soil protection layer of 10 cm thick on the China storage and drainage sheet factory must be sieved without particles larger than 6 mm. The soil protection layer must be tamped firmly to ensure that the dry capacity is greater than 1.5. The inspector must also take samples for inspection at any time. The backfill protection layer and block stone covering must be handled carefully.

When laying, it should also be noted that the geomembrane under the protective stone surface should be laid with a gravel or gravel cushion with a thickness of about 100 mm to avoid the influence of water level changes and other factors on the soil protection layer. The stones paved by manual hanging line should be closely embedded in the surface layer, and all the gaps should be filled with small stones.
