Geocell is a three-dimensional mesh cell structure formed by high-strength HDPE material and high-strength welding. It can expand and retract freely, can be folded during transportation, opened during use, and filled with materials such as sand, gravel, or soil in the cell, forming a structure with strong lateral limitations and high stiffness.It can be used as a cushion layer to enhance the bearing capacity of weak foundations, or laid on slopes to form slope protection structures. It can also be used to construct support structures, making construction convenient and fast.
