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.
