PP Biaxial Geogrid

The properties of PP Biaxial Geogrid, 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 materials. 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 machanism is highlu 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.
