If the geomembrane laying is cut, its size shall be measured accurately and cut according to the actual situation. Generally, do not cut according to the size shown in the figure. When laying the geomembrane, the welding seam shall be reduced, and the raw materials shall be saved as much as possible on the premise of ensuring the quality.
In the corner and abnormal section, the joint length shall be shortened to avoid leakage and other problems.
During the laying of geomembrane, the artificial fold should be avoided as much as possible. In case of cold weather and low temperature, it shall be tightened and leveled as much as possible.
After the geomembrane is laid, walking on the membrane surface and moving tools shall be reduced. Any object that can cause harm to the anti-seepage membrane shall not be pressed on or carried on the geomembrane to walk, so as to avoid accidental damage to the geomembrane.
