Geocells are a type of geosynthetic material widely used in construction and civil engineering projects. They consist of a honeycomb-like structure made from polymer strips that are joined together to form flexible, three-dimensional cells. These cells can be filled with soil, gravel, or other materials to create a stable and reinforced structure. The versatility of geocells makes them an essential tool in various applications, particularly to protect slopes from erosion and help stabilize the surface, as well as in erosion control, slope stabilization, and load support. This article explores the uses, benefits, and characteristics of geocells, as well as how they compare to other geosynthetic materials like geogrids.
