The StructureScan™ Mini HR is GSSI’s all-in-one high-resolution GPR system for concrete inspection. With a 2600 MHz antenna, this handheld system locates rebar, conduits and post-tension cables in depths of up to 16 inches (40 cm).

The StructureScan Mini HR is available in two models; 2D, for real-time target location and 3D, for an x-ray like image. Ideal for complex areas, the StructureScan Mini HR can delineate small targets with superior vertical and horizontal resolution.

Typical uses for StructureScan Mini HR include:

  • Concrete inspection – locate metallic and non-metallic targets in walls, floors and ceilings
  • Structure inspection – bridges, monuments, walls, towers, tunnels, balconies, garages, decks
  • Condition assessment – map relative concrete condition for rehab planning
  • Measure slab thickness
  • Void location

GSSI offers several optional software packages that allow users to post-process StructureScan Mini data for further interpretation.

RADAN™ for StructureScan Mini

RADAN for StructureScan Mini is a post-processing software package for the StructureScan Mini Series. It is designed to process, view, and document 2D and 3D data collected with the StructureScan Mini and StructureScan Mini HR. The software features bold and intuitive menu screens and clear data views for easy interpretation and enhanced post-processing capabilities.

Data Processing And Annotation

  • Processing of 3D data sets collected with the StructureScan Mini and Mini HR
  • 3D target input – customize size and color of targets
  • Virtual 3D borehole
  • Multiple color table and transform options
  • Windows® 7 based user-interface


  • Background Removal filtering
  • Data Migration (focusing)
  • Gain (Contrast) Control
  • Use Ground Truth for accurate depth calculations

Report Building

  • Report Writer – custom report output using MS Excel
  • Copy data images to third party software for documentation purposes
  • Add targets as colored circles and export target information in an Excel format
  • Save data images as a JPG file
  • Print to all Windows supported printers
