Product performance

　　Biaxial welded geogrid takes PET and PP as the main materials, adds anti-aging agent and other additives, and is mechanically stretched into refined ribs at low times. The geosynthetics formed by special ultrasonic welding are at right angles to the plane longitude and latitude. According to the project needs, different mesh diameters and rib widths and thicknesses are used to change the tensile force of the ribs, producing extremely high tensile modulus under low strain capacity, Fully utilizing the interlocking effect of the grid on the soil, the longitudinal and transverse ribs are woven into a web with high strength, low fracture tensile rate, and small creep coefficient. The temperature resistance range is -70 ° C to 180 ° C, with excellent UV resistance and microbial corrosion performance.

Applicable scope

　　Civil works such as roads, railways, embankments, abutments, construction roads, wharves, revetments, flood dikes, dams, mudflat treatment, freight yards, slag yards, airports, sports grounds, environmental protection buildings, soft soil foundation reinforcement, retaining wall reinforcement, high slope treatment, and exposed hydraulic works.
