Underground service strikes delay projects, blow budgets and create safety incidents. Mechanical excavation near critical infrastructure carries significant risk, even with site plans and locators. Assets shift over time, maps become outdated and unmarked services exist.
Non-destructive digging removes this risk.
NDD uses high-pressure water (up to 600 bar or 8500 psi) to break up soil, loosen sand and compacted surfaces. An industrial vacuum simultaneously removes the excavated material. This exposes underground utilities without damaging them.
We operate a combination vacuum and hydro excavation truck designed for Northern Territory conditions.
Specifications:
Defence facilities, NT Government sites, local government infrastructure, commercial developments and industrial projects. We understand the security protocols and compliance requirements for active sites.
Infrastructure Repairs and Upgrades
Repair or upgrade sewer, stormwater and water infrastructure without disrupting surrounding services. We excavate precisely where needed and minimise site restoration.
Asset Location and Exposure
We combine NDD with our GPR and Certloc capabilities to locate and safely expose underground assets before construction work begins.
Post Hole Digging and Foundation Work
Install safety barriers, signage, or foundation posts near underground services without risking damage to nearby utilities.
Pit Cleaning and Maintenance
Our jet cleaning removes sediment and debris from stormwater pits, sewer access points and drainage infrastructure. Six specialty nozzles clear blockages without damaging aging infrastructure.
Lower Risk
Mechanical excavation near underground utilities can damage cables, pipes and conduits. This triggers emergency repairs, project delays, and safety incidents. NDD removes this risk.
Better Value
Service strikes cost tens of thousands in emergency repairs and delay penalties. NDD has a higher hourly rate but eliminates catastrophic risk.
Precision
We work within centimetres of critical infrastructure. This exposes utilities without disturbing them and reduces site restoration requirements.
Compliance Documentation
Our AroFlo job management system provides photographic evidence, compliance records, and detailed reporting for ITP requirements.
