Geocell 1. It has free expansion and contraction, can be transported and retractable. During construction, it can be stretched into a mesh shape, filled with loose materials such as soil, gravel, concrete, etc., to form a structure with strong lateral restrictions and high rigidity. 2. Light material, wear resistance, stable chemical properties, resistance to photooxygen aging, acid and alkali resistance, suitable for different soil and desert soil conditions. 3. High lateral limit and anti-skid, anti-deformation, and effectively enhance the bearing capacity and distributed load of the roadbed. 4. Changing geometric dimensions such as geogrid height and welding distance can meet different engineering needs. 5. Free expansion and contraction, small transportation volume; convenient connection and fast construction speed.
