Plastic geocell is a three – dimensional net – shaped or honeycomb – like structure formed by connecting high – strength plastic sheets such as polyethylene (PE) and polypropylene (PP) through specific processes. These sheets are connected to each other at the connection points, forming individual cells. Visually, it resembles the shape of a honeycomb or grid.

Characteristics
High Strength and Toughness: Although made of plastic, it has high tensile strength and tear resistance. Meanwhile, it possesses good toughness, being able to withstand large external forces and deformations without cracking.
Corrosion Resistance: It has strong resistance to chemical substances such as acids, alkalis and salts. It is not easily corroded under different geological and environmental conditions, and can maintain stable performance for a long time.
Aging Resistance: After special treatment, it has good resistance to ultraviolet rays and aging. Even when exposed to the natural environment for a long time, its physical and mechanical properties will not decline significantly, featuring a long service life.
Drainage and Filtering: The structure of the geocell provides it with good drainage performance, allowing water to pass through quickly. Meanwhile, it can act as a filter to prevent soil particles from being washed away by water flow.
Foldability and Easy Construction: The plastic geocell can be folded into a small volume when not in use, which is convenient for transportation and storage. At the construction site, it is very easy to unfold and install, which can greatly improve the construction efficiency and reduce the construction cost.
Functions
Soil Reinforcement: Through the lateral confinement of the geocell on the soil, the movement of soil particles is restricted, thereby improving the overall strength and stability of the soil, enhancing the bearing capacity of the foundation and reducing foundation settlement.
Prevention of Soil Erosion: When used on slopes or riverbanks, it can effectively fix the soil, slow down the scouring of the soil by water flow, and prevent soil erosion and landslides.
Promotion of Vegetation Growth: In ecological slope protection, desert control and other projects, the cells can be filled with soil and planted with vegetation, providing a stable growth environment for the vegetation and promoting the development of vegetation roots, thus achieving ecological restoration and environmental protection.
Application Areas
Transportation Engineering: It is used for the reinforcement of road and railway subgrades. Especially in poor geological conditions such as soft soil foundations and collapsible loess foundations, it can significantly improve the stability and bearing capacity of the subgrades and reduce the occurrence of pavement diseases. It can also be used for the protection of road slopes to prevent slope collapses and soil erosion.
Water Conservancy Engineering: It can be applied to the protection and reinforcement of riverbanks and dams, enhancing the scouring resistance of the soil and withstanding the erosion of flood water and other water flows to ensure the safe operation of water conservancy facilities. It can also be used for the seepage control and reinforcement of channels, improving the water conveyance capacity and durability of the channels.
Environmental Protection Engineering: In projects such as landfills and tailings ponds, it is used for slope protection and foundation reinforcement to prevent the leakage and loss of garbage or tailings and reduce pollution to the surrounding environment. In desert control and land reclamation projects, it can fix sand dunes and improve the soil, creating conditions for vegetation growth and promoting the restoration of the ecological environment.
Landscape Engineering: In the construction of parks, squares, golf courses and other landscapes, it is used for ground reinforcement and drainage, providing a good foundation for the growth of lawns, flowers and other vegetation. Meanwhile, it improves the bearing capacity of the ground to meet the passage requirements of pedestrians or vehicles.
