PP Biaxial Geogrid Plastic Engineering Construction Geogrid
Biaxial Plastic Geogrid Introduction
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.

Biaxial Plastic Geogrid Precautions
1. The turning or braking of vehicles on the geotextile should be avoided as far as possible, especially when paving the asphalt surface course, any sharp turning or car killing sliding may bring up or damage the geotextile.
2. Construction under rainy, humid or cold weather conditions will affect the bonding strength and overlay effect of the coating.
3. Traffic must be closed during laying. Except for construction vehicles, other vehicles are allowed to pass through the geotextile only in case of emergency.
4. If there is slippage of paver when paving hot mix asphalt mixture, a small amount of stone chips can be sprinkled on the surface of tack coat oil.
Generally speaking, when we master the construction points of geotextile skillfully, we can make it play a greater economic benefit and make greater contribution to our urban construction.
Plastic Geogrid Mesh Feature:
1. High tensile strength at both longitudinal and transverse direction.
2. High tension resistance,high plane torsion resistance modulus,good creep resistance and stable chemical nature.
3. High mechanic damage resistance and durability and large friction factor with sandy stone.
4. Improve bearing force of foundation and increase diffusion angle.
