Types of Geogrid
Geogrids are flexible, synthetic meshes which are manufactured specifically for slope stabilization and earth retention in retaining walls. These grids are available in a variety of materials, sizes and strengths. They can be made of high tensile strength plastics or woven polyester yarns and are typically packaged at the factory in rolls. The grids are rated by Long-Term Allowable Design Strength (LTADS) with values ranging from 500 to 4,000 pounds per linear foot (7.3 kN/m to 58.4 kN/m).
