Two-way geogrid 
 Two-way stretch plastic geogrid, a material of this grille Uniaxial geogrid and chemical properties are not lively, high polymer materials through the extrusion process, then the longitudinal and transverse tensile formation. The material on the vertical and horizontal have great tensile strength, such a structure in the soil to provide a chain system, applicable to a large area of ??permanent bearing subgrade enhancement.
