Geocell is a three-dimensional mesh cell structure formed by high-strength HDPE sheet material and high-strength welding. Generally, it is made by Ultrasonic Needle welding. Due to the needs of the project, some holes are punched on the diaphragm, which is flexible and flexible, and the transportation can be shrinkable. During construction, it can be stretched into a net, filled with loose materials such as soil, gravel, concrete, etc, A structure with strong lateral restriction and large rigidity is formed.
