Geocells are primarily manufactured from High-Density Polyethylene (HDPE), although materials such as Novel Polymeric Alloy (NPA), polypropylene (PP), and polyester-based polymers are also used for specialized applications. HDPE is the most widely used material because it offers an excellent combination of flexibility, durability, chemical resistance, and environmental stability. The polymer sheets are textured and perforated to improve friction, drainage, and interaction between the cell walls and infill materials. These materials are resistant to ultraviolet (UV) radiation, chemicals, biological degradation, moisture, and temperature variations, allowing geocells to perform reliably in harsh outdoor environments for many years. Their high tensile strength enables the cellular structure to withstand heavy traffic loads and dynamic stresses without deformation. The perforated design improves water drainage while reducing hydrostatic pressure, making geocells suitable for both drainage and reinforcement applications. These engineering properties ensure long-term structural performance in roads, slopes, retaining structures, and other infrastructure projects.
