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
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.
