Triaxial geogrid is a unique type of geogrid. This product is made from high-density polyethylene. Triaxial geogrid has a stable triangular structure. Based on the stable triangle form, its multi-directional structure is an innovation. This triangular structure can provide an enhanced bearing system, which can reduce the thickness of layers. For example, the application of triaxial geogrid in asphalt pavement can greatly reduces the layer of asphalt.
