Horizontal Directional Drilling (HDD)

Complex crossings. Delivered with control.

Cape Dunstans delivers HDD projects from feasibility and engineering through to construction and reinstatement, using fully self-performed crews and specialised equipment.

Our capability combines in-house engineering, modern drilling systems and experienced field teams to deliver complex underground infrastructure safely and reliably. We support power, water, gas and communications projects in environments where open-cut construction is not practical.

With one of the most advanced HDD fleets in Australia, we deliver crossings exceeding 2,000 metres across a wide range of ground conditions, including hard rock and mixed geology.

Where HDD makes the difference

We deliver trenchless installations where surface disruption, environmental sensitivity or asset interfaces increase construction risk.

Typical environments include:

Urban and congested utility corridors
Major road and rail crossings
River and waterway crossings
Coastal and outfall installations
Substation and utility interfaces
Environmentally sensitive areas
Remote and regional locations

Our capability

We construct the underground infrastructure your project depends on across utilities, resources and communications.

Infrastructure we install:
