What Are Biaxial Geogrids?
Biaxial geogrids are polymeric materials designed for soil reinforcement. They consist of a grid structure with uniform apertures, enabling high tensile strength in both longitudinal and transverse directions. This dual-axis strength distribution makes them ideal for applications where load distribution is critical.
Applications of Biaxial Geogrids
- Soil Stabilization: Biaxial geogrids improve load distribution over weak or unstable soils, minimizing deformation and settlement.
- Pavement Reinforcement: Used under asphalt or concrete pavements, these geogrids enhance structural integrity and extend pavement life.
- Retaining Walls: They help in the construction of mechanically stabilized earth walls, offering stability and reducing earth pressure on retaining structures.
- Railway and Road Embankments: Prevent subsidence and ensure uniform load distribution.
