Construction Technology
Geomembrane paving is completed, should minimize walking on the membrane surface, moving tools, etc., where the geomembrane can cause harm to the object, should not be placed on the membrane or carry walking on the membrane, so as not to cause accidental damage to the membrane. When laying geomembrane, we should strive to weld less, under the premise of ensuring the quality of welding, and try to save raw materials. The lap width of the joints between the membrane and the membrane is generally not less than 10cm, and the weld seams are usually arranged parallel to the larger slope, i.e. along the direction of the slope.
