We have developed a selection of Mobile Ground Penetrating Radar (GPR) solutions to allow for rapid, efficient, and ultra-high-resolution data acquisition over large areas and in live traffic environments. In each case, a multi-antenna GPR array is deployed to a Chapter 8 compliant survey vehicle, capable of covering a large swath in each pass. Data can be acquired at highway speed reducing and in some cases removing, the requirement for traffic management. A mobile radar solution minimises project costs, the time required on-site and the risk of personnel working in live carriageways.

Our mobile GPR systems have been developed by our in-house team of geophysicists and highways surveyors, in association with equipment manufacturers 3D-Radar and Utsi Electronics, delivering rapid deployment, flexible configuration, and the highest available data quality.

BENEFITS OF MOBILE GPR

  • Reduced Cost
  • Exceptionally High Resolution
  • Rapid: travelling at highway speed, mobile GPR can capture up to 50 linear km of high-resolution, high-accuracy sub-surface image data per day
  • No Disruption: reduces, and in some cases removes, the need for traffic management or lane closures minimising project cost and disruption
  • Boots off the Carriageway: reduces health and safety risk to survey personnel
  • Gap Free Coverage: overlapping swaths augmented with traditional hand-push GPR for a comprehensive survey coverage
  • Optimum Data Quality: multi-frequency solution to optimise depth resolution and penetration

DEPLOYMENT OPTIONS

Highways Survey Vehicle: our custom-built Chapter 8 Highways Survey Vehicle (HSV) is configured for the deployment of our 3D-Radar DXG-Series antenna array. To facilitate safe and effective highways working, the system can be controlled from within the cab whilst the vehicle is in motion.

Rough Terrain: just like our Highways Survey Vehicle, our rough terrain solution is a modular design that can incorporate either our systems from 3D-Radar or Utsi Electronics allowing for a bespoke array configuration to suit site conditions and target requirements.

APPLICATIONS

  • Highways Survey: pavement construction analysis, material condition analysis (voiding, moisture, delamination/debonding)
  • Airport Runway Survey: condition assessment
  • Buried Utility Mapping: PAS128:2014 survey, route proving, reconnaissance survey
  • Site Investigation and Archaeology: underground infrastructure mapping, depth to bedrock assessment
  • Rail Survey: ballast condition survey, services mapping

ACCURATE POSITIONING

For accurate data positioning, our mobile GPR solution is integrated with a mobile mapping system – benefiting from the highest order of trajectory accuracy in all environments. Whilst the mobile GPR maps the subsurface infrastructure, the mobile mapping system simultaneously captures above ground infrastructure providing a full LiDAR point cloud and 360-degree images of the site.

Added Value: the photographic and LiDAR data sets captured by the mobile mapping system can be utilised for a number of purposes including topographical feature extraction, visualisation and asset management. We can supply the mobile mapping data in several formats including via U-GIS, our cloud-based underground GIS platform.

We have developed a cloud-based data delivery platform U-GIS, to provide our customers with an easy way to view, measure and model their above and below ground survey data in one place. Get the most out of your 3D mapping data with U-GIS. Cick to find out more.
