Underground Asset Detection

Expert Underground Services Location and Mapping 

We specialise in the accurate location and mapping of all underground services. These services encompass a wide range of domestic and commercial utilities, including:

  • Domestic water and fire services
  • Gas networks
  • High-voltage and low-voltage electrical networks
  • Telecommunications
  • Stormwater and sewer assets


We can accurately trace and locate even the most challenging underground services using cutting-edge technology and proven methods.

Our Specialties Include:

  • Telecommunications: As Telstra Accredited locators, we employ radio detection equipment to accurately trace and locate telecommunications without causing any disruption to communication lines.

  • Water and Gas Services: We employ standard Radio Detection techniques to locate metallic water and fire services. A transmitter sends a radio wave signal, allowing our receiver to locate the underground pipe accurately.

  • Sewer and Storm Water Pipes: We use a traceable fibreglass rod or sonde to map sewer and stormwater pipes accurately. This technology is inserted into these pipes to trace their length and depth precisely.


  • Non-Metallic Gas and Water (PVC): We employ vacuum excavation for non-metallic services such as PVC water and gas pipes (Non-Destructive Digging). This advanced method is effective in determining the location and depth of these services, whereas standard radio detection techniques may need to be more effective.


If a service cannot be traced via standard techniques, we also offer Non-Destructive Digging methods to determine the service depth and alignment accurately.


  • Data and Reporting:
    We use AutoCAD, portable computers, and our locating experience to create comprehensive, easy-to-read plans of underground assets. This permanent record of existing underground services allows future planning and work to be conducted efficiently and safely.
