Biaxial geogrids

Biaxial Geogrids can be made from materials including plastic, polyester and fiber-glass by way of weaving, knitting, extruding or other method. Biaxial geogrid features equal strength in both longitudinal and transverse directions, creating an interlocking system that can effectively bear and diffuse forces throughout the soil.

Biaxial geogrids are designed to spread loads over a large area, reducing excavation needs and providing an economical design. Their ribs interlock with the surrounding soil particles, increasing bearing capacity and reducing time and cost associated with placement and construction.

Biaxial geogrids ribs thickness and unit weight
Biaxial geogrids rib thickness (1mm) , 150g/m²
Biaxial geogrids rib thickness (1.5mm) , 230g/m²
Biaxial geogrids rib thicknesses (2mm) , 300g/m²
Biaxial geogrids rib thicknesses (2.5mm), 350g/m²
(The above is the estimated value, the tolerance is 1-2g/sqm)

Application
Biaxial geogrid provides a long-term resistance to deformation and enhances the bearing capacity of road and ground foundations, extending their service life, it is used to:
1, prevent caving in or cracks in the road or ground surfaces and keeps them looking neat and tidy.
2, stop culverts from cracking.
3, improve soil slope stability and prevents soil erosion.
4, reduce the required thickness of bedding layers, saving costs.
5, support slope vegetation mesh mats to green the environment.
6. replace metal mesh for coal mine shafts.
