A polyester geogrid is a type of geosynthetic material made from high-strength polyester fibers. These grids are woven or knitted into a grid-like structure and then coated with a protective polymer, such as PVC, to enhance durability and resistance to environmental factors. Polyester geogrids are commonly used in civil engineering and construction for soil stabilization, reinforcement, and load distribution. They are particularly effective in applications such as road construction, retaining walls, and embankments, where they help improve the mechanical properties of soil and prevent erosion. Their high tensile strength, flexibility, and resistance to chemical and biological degradation make them suitable for a wide range of geotechnical applications.
