to 6m, resulting in high tensile strength at low strain capacity. Longitudinal and transverse ribs work together to fully utilize the geogrid's embedded locking effect on the soil body. During production, the polyester geogrid is pressed with a rough pattern to enhance the roughness of the surface and improve the friction coefficient between the geogrid and the synthetic soil body. Polyester geogrids are not eroded by acid, alkali, salt solutions, and oil at room temperature, do not dissolve in
