Biaxial Steel Plastic Geogrid

The steel-plastic geogrid is made of high-strength steel wire, specially treated, and polyethylene (PE), and other additives are added to make it a composite high-strength tensile strip through extrusion, and the surface has rough embossing, which is high. Reinforced belt. From this, the single belt is woven or sandwiched at a certain distance vertically and horizontally and is formed by welding its junction points with a special strengthening bonding fusion welding technology, which is a steel plastic geogrid. Steel plastic geogrids are mainly used in highways, railways, ports, etc.

    What is Biaxial Steel Plastic Geogrid ?

    The steel-plastic geogrid is made of high-strength steel wire, specially treated, and polyethene (PE), and other additives are added to make it a composite high-strength tensile strip through extrusion. The surface has rough embossing, which is high. Reinforced belt. From this, the single belt is woven or sandwiched at a certain distance vertically and horizontally. It is formed by welding its junction points with a special strengthening bonding fusion welding technology, which is a steel plastic geogrid. Steel plastic geogrids are mainly used in highways, railways, ports, etc.

    How does biaxial geogrid work?

    If the soil in the area where you will be adding a dense load (such as slabs, railway sleepers, trucks or lorries) is too soft, the pressure will force the soil to warp. A Geogrid will help to secure the soil through compacting the aggregate which furthermore enhances the bearing capacity of the underlying ground. In short, it strengthens the ground and stops it from disappearing in heavy traffic, preventing rutting – etc.

    Unlike when the load is introduced to the soil alone, the geogrid forces the heavy load’s pressure to be spread over the entire surface area of the grid, due to the subgrade having strength in both directions. It’s a similar reason to why, if you were walking on thin ice, you are better off laying down to spread your body weight over a larger surface, it’s the same principle here.

    This essentially means once the Biaxial geogrid is set out and the heavy load is put in place the soil beneath the grid compacts and the subrade’s strength is further enhanced. This means that it is very cost effective by saving both labour and maintenance expenses. 

    Works really well for farm tracks etc or country lanes that lorries drive up and down. It helps to stop the ruts caused by the weight on the tyres which otherwise would need regularly refilling.
