Experts in Service Locating

D-Tech have a team of dedicated underground services locators who can trace & map out subsurface utilities at your site, allowing these assets to be protected & understood.

Our technicians lift all on site pits and manholes, collecting & recording information such as pipe and chamber sizes, depths, direction of flow, conduit sizes, materials, configuration and utility type.

On Site service findings are photographed & our in-house draftsman is able to accurately update CAD files with the technicians findings. If CAD files are not available, D-Tech is able to provide clear detailed PDF plans on Satellite images.
D-Tech uses both electromagnetic cable locating (EML) and ground penetrating radar (GPR) technology to trace & locate underground utilities.

• EML Locating – Used to locate conductive utilities such as metallic pipes, electrical and communication cables
• Ground Penetrating Radar – Used to locate non conductive material such as Poly or Nylon gas lines, blue brute and PVC water mains, empty conduits, underground storage tanks, underground voids & abnormalities in subsurface compaction.
• Traceable Rod with EML – Used to locate accessible empty pipes or conduits, i.e. Sewer and Storm water pipes and empty conduits.

All our work complies to the Australian Standard AS-5488.1:2019 classification of subsurface utility information.

D-Tech can undertake such investigations for the following purposes:

• Development Sites – to ensure that all existing services are located to avoid any complications to ongoing works or to new services being installed.

• Construction Sites – to determine the extent of services within the concrete for old and new buildings prior to core penetrations of redevelopment of any one area.

• On Site Data Collection – detailed drawings obtained from site and collated with plans and exisiting service provider infrastructure drawings from relevant authorities.
