Directional Drilling

Discover precision and efficiency with our directional drilling services. We minimise disruption, navigate obstacles and ensure reliable underground installations for your projects.

Our hydro excavation and potholing services use high-pressure water and vacuum technology to safely excavate soil and expose underground utilities, minimising the risk of damage.

Our cable locating services use advanced technology to quickly and accurately locate underground utilities and cables. We’ll help to enable safe excavation and construction on your project.

Our ground penetrating radar technology provides detailed information about the location and depth of underground utilities, structures and other features, making excavation projects safer and more efficient.
