Our G5 Sub-base is produced from 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 G5 sub-base is used in a variety of places such as:
- Sub-base for road ways
- Sub-base for parking areas
- Backfilling and civils works to create platforms for buildings
Our G5 sub-base is suitable for both small scale and high spec construction projects.
