Three-way plastic geogrid plastic one-way stretch geogrid and the basis of the two-way stretch plastic geogrid, new product development and improvement, the material is a polymer (polypropylene) by squeezing, stretching, into a plate, punching process, after the longitudinal, transverse stretch, and Z directions tensile, the item is stretched in one direction from an increase in the three-dimensional directions. Three geogrid advantages: The material in the whole only in the longitudinal and transverse have great tensile strength, and the roadbed full contact, increasing the frictional force to prevent the subgrade soil erosion. Three geogrid is more important to the structure and soil in the soil in a three-dimensional direction with respect to binding, thus achieving different directions to prevent soil erosion, enhance the role of preventing the sedimentation of the roadbed. Three geogrid characteristics: in use is one-way and two-way geogrid geogrid anti-settlement several times, is the ideal product to enhance the subgrade life! Truly three-dimensional geogrid! It is in the the Biaxial and one-way geogrid new alternative products. Three-way geogrid technology indicators: the rib section into a rectangle, bore an equilateral triangle, outside of the regular hexagon, a low 2% secant tensile modulus strength index and 5% higher secant tensile modulus strength index, and the foundation of the force principle, it is the ideal product for soft ground treatment! The plastic geogrid divided into one-way stretch plastic geogrid, two-way stretch plastic geogrid, three-way plastic geogrid and multi-directional plastic geogrid
