Geotextile manufacturers remind the majority of constructors: Before the construction of geotextile and composite geomembrane, attention should be paid to the stability of various parameters, including the following points:

　　 1. The geotextile roll should be protected from damage before installation and unfolding. Composite geomembrane geotextile rolls should be stacked in a flat place without water accumulation, the stack height should not exceed the height of four rolls, and the identification film of the roll can be seen. Geotextile rolls must be covered with opaque materials to prevent UV aging. In the storage process, the integrity of the label and the integrity of the data should be maintained. To

　　2. The seams of the sewn geotextile include one-line stitching and chain stitching. The thread used for stitching should be a resin material with a minimum tension of more than 60N, and have chemical resistance and UV resistance equivalent to or exceeding that of geotextile.

　　3. The worn geotextile must be repaired by laying and thermally connecting small pieces of geotextile. The small pieces of geotextile must be at least 200mm longer than the edge of the defect in all directions. The thermal connection must be strictly controlled to ensure that the geotextile patch and the geotextile are tightly combined and do not damage the geotextile. To

　　4. At the bottom of the landfill, if the length of the crack exceeds 10% of the width of the coil, the damaged part of the composite geomembrane must be cut off, and then the two parts of the geotextile are connected
