One-way stretch geogrid is polymer by extrusion pressed into sheets and then washed rules mesh, and vertical stretching. This process is a linear polymer into the oriented state and the formation of uniform distribution, node strength oblong mesh overall structure. This structure has a very high tensile strength and tensile modulus, especially my company such products more super high international level of early (elongation of 2% -5%) tensile strength and tensile modulus . Soil provides the ideal force commitment and the proliferation of chains. The product tensile strength (> 150Mpa), to adapt to a variety of soil, is widely used in reinforced reinforcement. Features one-way geogrid have high tensile strength and high modulus of elasticity and durability and other characteristics; improve subgrade bearing capacity, improve the retaining wall, bearing capacity dam; to extend the project life.
