Safe
- Safe Compressed air excavation air exposes live cables, pipes and tree roots without contact - no strike risk.
- Precise excavation helps protect tree roots and other sensitive underground assets that may be damaged by conventional mechanical excavation methods.
- Reduced risk of underground asset strikes helps prevent service outages, costly repairs, project delays, and potential safety incidents.
- A smaller excavation footprint and reduced reliance on manual digging help minimise worker exposure to excavation-related hazards.
- High-pressure air is directed through a specialised nozzle to safely break up compacted soils, enabling controlled and highly accurate excavation around critical infrastructure.
Eco-Friendly
- Dry spoil is reused on the spot. No slurry, no tankering, no waste-disposal delay and no need for imported fill materials.
- Lower fuel consumption and emissions, as excavated material can remain onsite rather than being transported to disposal facilities, reducing vehicle trips
- No water is introduced into the excavation process, helping to prevent contamination, minimise environmental impact, and protect surrounding waterways.
Comparing with Hydro Over a 12 Month Period
Efficient
- The dig runs non-stop, keeping your programme moving and your site clear sooner.
- The ability to tip excavated material onsite reduces handling and disposal time and improving overall productivity.
- A large 250mm intake hose efficiently removes soil, aggregate, spoil, and debris while minimising the risk of blockages and unplanned downtime.
- Reduces the equipment, personnel, and working area required for excavation activities, helping minimise disruption to surrounding operations.
- Faster excavation and spoil management can shorten project timeframes, reducing disruption and associated costs.
- Precise, non-destructive excavation reduces the risk of underground asset damage, helping avoid costly repairs and delays while minimising clean-up and reinstatement requirements.
Accessibility
- Vacuum hose extension pipes provide access to excavation sites up to 100 metres horizontally or 50 metres vertically from the AirVac unit, making it ideal for difficult-to-reach locations.
- Our Rail Low Loader enables AirVac operations across the KiwiRail network, providing safe and efficient access to rail corridors and remote trackside excavation sites.
- With experienced crews and operational capability located throughout New Zealand, we can efficiently mobilise to projects nationwide, including remote and challenging locations.
- For long-term projects, AirVac units can be securely stored onsite where suitable, reducing travel requirements, improving responsiveness, and helping to minimise project costs.
