PP Biaxial Geogrid
The properties of Biaxial Geogrids, made in Polypropylene (PP) with their square apertures, high tensile strength and optimised geometry of nodes and ribs make them equal to any other similar material. The reinforcing action of PP Biaxial Geogrids lies mainly in confining soil and increasing its shearing resistance by a process of interlocking between the square ribs and the soil. The load dispersal effect from the interlocking mechanism is highly effective and can reduce sub-base thickness and construction cost. PP Biaxial Geogrids can be used with any kind of mechanical fill material. Two aperture size ranges are available for optimum matching with project fill.

PP Biaxial Geogrid
The use range of the Biaxial stretch grid is extremely wide, not only applicable to highway, railway roadbed reinforcement, and suitable for various kinds of dam slope protection, large airport, parking lot, freight wharf etc. the loading capacity of permanent foundation reinforcement.
1: Increase the capacity of the foundation, and extend the service life of the embankment.
2: Prevent pavement collapsed or crack, keep the surface of the road beautiful and tidy.
3: Construction is convenient, time saving, and shorten the construction period, reduce maintenance costs
4: Prevent culverts cracks
5: Enhance slope to prevent soil erosion
6: Reduce the cushion layer thickness and save cost
7: Support plant grass slope stability and afforest environment
8: Replace metal nets, used in coal mine as top nets
The use range of the Biaxial stretch grid is extremely wide, not only applicable to highway, railway roadbed reinforcement, and suitable for various kinds of dam slope protection, large airport, parking lot, freight wharf etc. the loading capacity of permanent foundation reinforcement.
Applications of PP Biaxial Geogrid
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.
