Product Details

PP Biaxial Geogrid

Material; polypropylene

Tension; 15-55KN(support customization)

Biaxial geogrids are called biaxial geogrids because they contain similar strength in both the machine and cross machine direction. It does not necessarily mean they have the same strength in both directions just that the geogrids are designed to provide support in both directions. Biaxial geogrids can be knitted, woven or extruded but the majority are extruded. Extruded biaxial geogrids are generally extruded using polypropylene with a small amount of carbon black added to give the geogrid the ability to resist UV degradation. Biaxial geogrid's primary application is for use in base stabilization. By placing the geogrid in the gravel base so that it can interlock with gravel above and below you can extend the service life or reduce the total amount of aggregate needed for a road or parking lot application.

1. Increase the bearing capacity of the roadbed and foundation and prolong their service life.
2. Prevent road surface and foundation from sinking or flawing, keep clean and beautiful ground surface.

3. Convenient construction saves time and labor, reduce mounting time and decrease maintenance expense.

4. Prevent culverts from flawing.

5. Enhance earth slope and prevent water loss and soil erosion.

6. Decrease under layer thickness and save manufacturing cost.

7. Enhance the stability of side slope turf net patch to improve greening.

8. Replace wire netting used in mine as intermediate ceiling netting.
