Non Destructive Excavation Specialists
Saving lives by protecting your projects' undergound assets..
The ground we walk on sits above a vast city of infrastructure.
Underground optical fibres, gas mains, electrical conduits, water pipes and other buried utilities provide us with our daily conveniences.
We have worked tirelessly for a decade to ensure that vacuum excavation is now considered the industry standard when digging in and around buried assets that can be easily damaged or destroyed by traditional excavation methods.
We use the latest technology on purpose built rigs and fully trained, highly experienced crews.
We IDENTIFY, LOCATE and PROTECT our city's UNDERGROUND SERVICES thus enabling some of the most recognised construction companies to safely expand out networks, buildings, substations, roads and rail systems.

We have a large fleet of Sydney based trucks with slurry tank sizes up to 14,000 litres.
On-board pressurised water is used to loosen and 'non destructively excavate' the soil.
A vacuum source makes sure that all the excess water and soil is efficiently removed from the site ensuring the underground infrastructure remains intact and clearly exposed.
This slurry is collected in our self-contained trucks for removal from site.
