Our G2 Sub-base is produced from a combination of drilled and blasted blue and brown granite rock mined at our quarry. This rock is further crushed down to <37.5mm to produce a manufactured crushed aggregate sub-base.
Producing crushed aggregate sub-base from drilled and blasted rock ensures that a high strength material is used.
Our G2 sub-base is used as layer works of road ways and parking areas.
Our G2 sub-base is suitable for both small scale and high spec construction projects.
