Cellular restraint systems are often referred to as "geocells." Non-cohesive soil is confined within the honeycomb wall. Composite materials form rigid to semi-rigid structures. The depth of the geogrid and the size of each honeycomb unit can be changed according to design requirements.
Generally, the filling is a sandy or gravel-like material. However, the filler can be ordinary concrete, depending on the actual application. The surface of the geocell is textured to increase soil-geocell wall friction.The geocell wall is punctured to assist in immediate dissipation of developed porewater pressures due to increased stresses within the infill of the individual cells.
Soil consolidation of slope protection geocell:
（1）A three-dimensional structure of a loofah-like mesh mat used for grass planting and soil consolidation. The texture is loose and flexible, with 90% of the space left for filling with soil, gravel and fine stones, and the plant roots can pass through it, making it comfortable , Regular and balanced growth. The grown turf connects the mat, turf, and soil surface firmly.
（2） As plant roots can deepen 30-40cm below the ground surface, a solid green composite protective layer is formed before the turf grows, which can protect the surface of the ground from wind and rain. It can firmly insist that the grass seeds are evenly distributed on the slope, and avoid the loss of wind and rain. The black mesh pad can absorb a lot of heat energy, add ground wetness, promote seed germination, and extend the growth period of plants.
（3） The composite protective layer formed by plants after they grow up can enjoy the erosion of high water level and high flow rate
