Ground penetrating radar sends a pulse into the ground and reads what returns, so it can help investigate items that will not carry an electromagnetic signal. That can include non-conductive pipe, unrecorded assets, voids and changes in the ground itself. Results are interpreted, and radar does not detect everything that may be present.
Radar is used alongside the plans, the asset owner information and electromagnetic tracing rather than in place of them. It is generally brought in once those have been reviewed and there is still uncertainty across the work area.
VACIT operates an IDS GeoRadar Stream C, a 3D radar array built for underground utility investigation, alongside a dedicated locating vehicle and the vacuum excavation fleet. An array collects a wider swathe of data than a single-channel unit. What it can resolve on any given site depends on the conditions there, on how the survey is set up and on what is being looked for.
Radar range is not a fixed number. It depends on the ground the signal travels through, on the equipment and antenna used, and on the size, depth and material of what is being looked for. Wet clay and conductive fill absorb the signal and shorten the range. Drier, coarser ground lets it travel further. A depth quoted before anyone has seen the site describes equipment, not your job.
Electromagnetic locating suits services that will carry a signal and can be traced directly. Radar can help investigate items that will not. Neither method shows the asset itself, so where a service is critical, careful excavation can expose it and make its position visible at that point. Which methods suit a work area depends on what is expected there and what the work needs.
VACIT runs radar investigations in Brisbane, the Gold Coast, Ipswich, Logan, the Sunshine Coast and the wider South East Queensland corridor, dispatched from the Mount Cotton operations yard. Send the site address, the area to be covered and the surface type so the survey and the site access are planned together.

To build a retaining wall, I needed sitelocator to locate sewer pipe underneath. Marco was so easy to communicate with also he keeps informs/updates me of what he was doing and how it works. If you need site locator for any reason, I strongly recommand him.
