Hydro Vacuum
Excavation
Our hydro vac excavation delivers precise, non-destructive digging that protects buried infrastructure. Ideal for confined spaces, around live services, and complex civil projects where traditional digging isn't an option.

See What's Below Before You Dig — Every Time
Our state-of-the-art underground utility locating service detects and maps the exact position of buried cables, pipes, conduits, and structures before any excavation or drilling activity begins.
We serve Brisbane, Gold Coast, and the wider South East Queensland region with pinpoint accuracy, keeping your project on schedule and your crew safe.
How does utility locating work?
We use electromagnetic detection and ground-penetrating radar (GPR) to map buried assets in real time, producing accurate depth and position data without disturbing the ground surface.
What hazards does it prevent?
Striking concealed power lines, gas mains, water pipes, or data conduits can cause project delays, costly repairs, and serious safety incidents. Our locating service eliminates that risk entirely.
Who should use this service?
Any contractor, developer, or site manager planning ground-penetrating activity — including trenching, drilling, piling, and landscaping — should locate utilities first.
