Glass fiber geogrid, also known as fiberglass geogrid, is a new type of geotextile substrate with excellent performance. It has excellent characteristics such as high tensile strength, good elastic modulus, low elongation, high and low temperature resistance, and aging resistance. Especially after the surface of fiberglass geogrid is modified and coated, it improves its composite performance with asphalt or concrete, enhances its wear resistance and shear resistance. Due to the use of appropriate alkaline glass fiber material for coating treatment, this product has excellent chemical resistance and microbial corrosion resistance.
