Ground Penetrating Radar Technology Return to Core Activities

The near surface surveying using Ground Penetrating Radar (GPR)  provides a digital sub-surface image in real-time. GPR measurements are capable of determining geological mapping, water content and the location of buried structures. GDS has access and utilises the latest GPR  technology designed for the appropriate project and task. The exact equipment specification and project requirements are defined during the project planning and conception.

GDS provide the following services depending upon the client’s individual requirements:

  • Full data collection service
  • Equipment  rental complete with delivery and introduction into the equipment operation
  • GDS operator to assist our clients with the  equipment operation


  • Pipe & cable detection
  • Water table assessment
  • Geotechnical site investigation
  • Non-destructive Testing
  • Concrete inspection

Project example: Mexico City subway - October 2010

Target 1 is clearly visible whereby Target 2 is masked by electrical noise and maybe a false reading caused by the electrical noise.
Target 3 is less visible however it is repeatable on several survey lines and on both tracks.

Project example: Concrete  slab, Tewksbury, UK - 2009

This image is from a project to detect the extent of possible subsidence caused by wide area flooding beneath a concrete slab.The blue area shows an anomaly that was further investigated with a borehole.
