Geocell is a three-dimensional cellular confinement system made of high-density polyethylene. It is used to stabilize granular soils and reinforce weak soils and subgrades. Geocells are also used to construct retaining walls, support structures, and to create soil-reinforced embankments. The system consists of modular panels that are filled with soil and connected together to form a honeycomb-like structure. The panels can be filled with any type of soil, including sand, gravel, and crushed stone. Geocells are an effective and cost-effective solution for a variety of construction projects.
