Biaxial geogrid is made of high molecular polymer through extrusion, forming and punching before longitudinal and lateral stretching. This material has considerable tensile strength in longitudinal and lateral directions. This chain structure can effectively bear and diffuse forces on soil and is applicable to large area permanent load bearing foundation as a reinforcement material.
Glass fiber geogrid is an excellent geosynthetic material used for road surface reinforcement, old road reinforcement, subgrade reinforcement and soft soil foundation reinforcement. It has become an irreplaceable material in the application of treating reflective cracks of asphalt pavement. This product is a semi-rigid product made of high-strength alkali-free glass fiber, which is made into a net-like substrate by international advanced warp knitting technology, and after surface coating treatment. It has high tensile strength and low elongation in both warp and weft directions, and excellent properties such as high temperature resistance, low cold resistance, aging resistance and corrosion resistance. It is widely used in reinforcement of asphalt pavement, cement pavement and subgrade, railway subgrade, dam slope protection, airport runway, sand control and other engineering projects.
