There are generally two methods for connecting the edges and corners of geomembranes: one is to use glue (the thickness of the membrane is less than 0.8), and the other is to use a professional welding machine for hot sealing welding (the thickness of the membrane is greater than 0.8). Of course, it also depends on the situation, and the construction site is also quite important. If it is a concrete road surface, the corners can be directly connected, with a overlap of about 20 cm, and two layers of concrete can be directly applied on top. If it is a water pool, it is recommended to use heat sealing welding, which is more reliable. If the area is small, special adhesive for geomembrane can be used.
