Geocell is a three-dimensional mesh structure made of high-strength polymer sheets (such as HDPE, PP, etc.) through ultrasonic welding. When unfolded, it presents a three-dimensional grid shape.
Geomembrane is a thin, extremely low-permeability sheet material made from high-molecular-weight polymers (high-density polyethylene, linear low-density polyethylene).
Geotextile are usually used to separate the clay layer and the drainage layer to protect the liner from damage. They are mainly used in civil engineering, water conservancy engineering, environmental engineering and other fields.
