Biaxial Tensile Geogrid
Biaxial tensile geogrids are mainly used for soft soil foundation reinforcement, and are subjected to stress in both longitudinal and transverse directions.
Biaxial tensile geogrids are geosynthetic materials with a regular mesh structure, made primarily of PP or HDPE. It is produced through a stretching process that aligns the polymer chains both longitudinally and transversely. They possess high tensile strength with balanced longitudinal and transverse properties, reasonable elongation, and excellent interfacial bonding performance, making them an ideal choice for two-dimensional stress applications, such as soft soil foundation reinforcement and road base enhancement. Our products can be manufactured according to GB/T, ASTM, ISO, and other standards, and all raw materials are pure new resin.
Production Process: biaxial tensile, and biaxial tensile injection molding.
The biaxial tensile process mainly includes sheet extrusion, punching, Longitudinal and transverse stretching, and heat setting treatment.
The biaxial tensile injection molding process includes producing plastic strips, arranging them longitudinally and transversely, connecting them at the joints by injection molding, and cooling and shaping.
Quality Control: The entire production process is monitored by automation. Strict factory inspections are conducted, to ensure that key quality control points fully comply with the standards.
After-sales Service: We have over one million square meters of construction experience, and our team can provide on-site construction services. We also offer remote technical guidance to assist with welding and construction.
Advantages
- Biaxial balanced high strength.
- Excellent deformation control capability: It can effectively restrain soil displacement and reduce uneven settlement.
- UV protection and aging resistance
- Injection molding of connection points lead to higher connection strength.

- Soft Soil Foundation Reinforcement:
- In soft soil foundation treatment for highways, railways, and airport runways, bidirectional geogrids are laid at the bottom of the fill layer, forming a "raft effect" that effectively restrains lateral extrusion, improves foundation bearing capacity, and reduces uneven settlement.
- Road Base Layer Reinforcement:
- Laying bidirectional geogrids in asphalt or cement concrete pavement base layers effectively disperses wheel loads, delays reflective cracking, and extends pavement service life.
- Large Load-Bearing Areas:
- In large load-bearing areas such as storage yards, parking lots, and warehousing bases, bidirectional geogrids combined with graded crushed stone form a composite load-bearing layer, significantly improving foundation bearing capacity.
- High Fill Reinforced Soil Retaining Walls:
- For reinforced soil retaining walls requiring higher strength and larger mesh sizes to accommodate coarse fillers, injection-molded bidirectional geogrids offer significant advantages.
- Railway Ballast Track:
- Lay between the ballast layer and the subgrade, preventing ballast from embedding into the subgrade and simultaneously providing reinforcement.
- Railway Ballast Track:
- Landfill bottom lining protection layer: As a protective layer above the seepage prevention system, the bidirectional geogrid can distribute the load of the landfill above and protect the HDPE geomembrane.
