Geogrid is a high-strength geosynthetic manufactured from polymer materials, typically polypropylene or polyester, formed into a regular grid structure. It is designed primarily for soil reinforcement, providing effective load transfer and improved interaction with surrounding soils or aggregates. Geogrids enhance structural stability, reduce deformation, and increase load-bearing capacity, and are widely used in road and pavement construction, embankments, retaining walls, slopes, and ground improvement applications.
