Air Excavation

Precise, dry excavation for sensitive sites

Air excavation is a dry excavation method ideal for underground utility excavation to expose assets without the use of moisture. A form of non-destructive digging, it is especially useful in areas where water-based digging might damage fragile infrastructure, compromise soil integrity, or require additional drying time.

InterGroup offers highly controlled air vacuum excavation services using compressed air to displace soil and a powerful vacuum system to remove debris. This method is preferred for sensitive projects near power cables, communication lines or tree roots. Our trained crews operate specialised dry vac trucks, delivering safe and efficient outcomes with minimal site disruption.

Why InterGroup?

With the most extensive vacuum fleet in New Zealand, we can mobilise quickly, access tight spaces, and operate longer without disposal downtime.

Our ability to offer both compressed air excavation and hydro excavation means we will always match the right tool to each task.
