Mobile Laser Scanning
Laser scanners carried on the move record roads, corridors and built assets as measured 3D data.
Ground Penetrating Radar in Australia
Our radar traces buried services, voids and structural features before a project breaks ground.

Two Ways We Use GPR
Multi-Array GPR
Our Stream DP system collects data through multiple antenna channels with double-polarised scanning, capturing a wide swath of the subsurface in a single pass. It suits complex sites and dense utility environments where services may cross the survey area at varying angles.
Mobile GPR
Our vehicle-mounted Stream UP system scans without contacting the pavement, collecting radar data while moving along roads and transport corridors. It suits long paved routes and extensive areas where surveys on foot would be slow.
Clear Data for Better Project Decisions
At UDM, we provide ground penetrating radar in Australia to investigate subsurface conditions without relying on excavation alone. We use GPR to collect information about buried utilities, structural features and other changes beneath the surface, then interpret the data so project teams can plan with a clearer understanding of site conditions. Our equipment includes single-channel, multi-channel and multi-array systems selected to suit the project and surface being assessed. Where a project also involves work within concrete, our concrete scanning service can provide a more targeted view before cutting, coring or drilling. Talk with our team about the survey scope and the information you need by calling (03) 6171 2555.
How Our Ground Penetrating Radar Service Works
We match the GPR approach to the investigation rather than treating every site the same. Utility detection and mapping can help identify conductive and non-conductive services and complement electromagnetic locating. Structural assessment and void investigation can support investigation of pavements, slabs and other structures where hidden features need to be understood. We process radar responses, geo-reference findings and translate field data into usable project information. Survey information can also support CAD, GIS and other project workflows where spatially referenced outputs are required.
Common questions
- What can ground penetrating radar detect?
- GPR can respond to changes in subsurface materials and may reveal utilities, voids, reinforcement and other buried features. Results depend on ground conditions, target depth and the equipment configuration used.
- Does GPR require excavation?
- GPR is a non-destructive investigation method and normally collects data from the surface. Targeted excavation may still be used separately where physical verification is required.
- What affects GPR survey results?
- Soil composition, moisture, conductive materials and antenna frequency can influence radar penetration and resolution. Survey design and interpretation therefore need to account for site conditions.
Other services
Projects often need more than one method. Explore the rest of our capability, or contact our team to discuss a combined scope.
Surveying & Spatial
Our surveyors set the control, levels and measured detail that design and construction work relies on.
Reality Capture
Laser scanning records a structure or site as measurable three-dimensional data.
UAV / LiDAR
Aerial capture records terrain, stockpiles and assets that are difficult to reach from the ground.
Utility Locating
Electromagnetic locating and radar help identify buried services before excavation or design starts.
Concrete Scanning
We locate reinforcement, conduits and post-tension cables before anyone cuts, cores or drills.
CCTV Pipe Inspections
A camera run through a pipe or drain shows the condition of the line from the inside.
