Geomembrane can be welded or bonded with special adhesive for geomembrane. But bonding is not as strong as welding. In addition, it also depends on the actual laying area and cost budget. If the area ranges from a few hundred to about 1000 square meters, adhesive bonding can be chosen; If the area is thousands or even tens of thousands of square meters, a welding machine should be chosen for welding, which can save costs.
