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.

Applications:
Make reinforce treatment for various kinds of soft soil foundation to evenly distribute load stress and reduce uneven settlement, not easy to generate static electricity, and flammability property good in the coal mine. It is easy to wash coal. 

Used in highway, railway, port, airport and municipal project. Support in the recovery working face of coal mine and roadway in the coal mine.
