Uniaxial plastic geogrids are a kind of polymeric net materials with square or rectangle hole formed by stretching. They are punched in the polymeric plate(materials are mainly polypropylene or high-density polythylene) made by extruding, and then stretched longitudinally in heating condition, only in one direction along the plate. They are widely used as reinforcement materials in maintenance projects of retaining wall, slope, dike and abutment.

Biaxial Plastic Geogrid
The materials of biaxial plastic geogrid are similar to the uniaxial plastic geogrid with inactive chemical properties, which are formed by being extruded from macromolecule polymers, then stretched in longitudinal and transverse directions. The materials have high tension strength in both longitudinal and transverse directions, and this kind of structure could provide a interlock system for the soil, that is suitable for the enhancement of roadbed with large area permanent bearing capacity, such as the treatment of soft soil foundation and reinforcing earth structures.

Usage:
Biaxial plastic geogrids are suitable for roadbed enhancement of permanent bearing capacity in dyke, side slope, tunnel wall, large airport, parking lot, wharf yard, etc
1.Increasing the bearing capacity of roadbed and prolonging its service life.
2.Preventing road surface and foundation from subsiding or cracking and keeping clean and beautiful ground surface.
3.Being convenient for construction,saving time and labor, shortening construction period and maintenance cost.
4.Preventing tunnel from cracking.
5. Enhancing slope stability, preventing soil andwater loss.
6. Decreasing underlayer thickness and saving cost.
7. Supporting stability of side slope grass mat  and improving greening.
8. Used in mining as intermediate ceiling netting instead of metal netting.
