StructureScan Optical


StructureScan™ Optical is the only concrete inspection tool on the market with an optical barcode reader and patented Smart Pad technology for easy wall and floor scanning. StructureScan Optical has revolutionized 3D data collection by simplifying an often complicated survey process while providing the most accurate results in the industry.

To fit specific concrete needs, GSSI now offers two StructureScan versions. One can choose between the general-purpose 1600 MHz antenna with a depth of penetration of up to 18", and the new high-resolution 2600 MHz antenna, ideal for locating closely spaced targets, with a depth of penetration of up to 10".

Typical Uses for StructureScan Optical Include:

  • Concrete inspection – locate metallic and non-metallic targets in walls, floors
  • Structure inspection – bridges, monuments, walls, towers, tunnels, balconies, garages, decks
  • Condition assessment – map relative concrete condition for rehab planning
  • Ceiling inspection
  • Measure slab thickness
  • Void location
  • Data collection pads with optical bar codes that simplify data collection
  • Locate rebar, post tension cables, conduits (PVC and metal) in real time
  • Most accurate GPR data results on the market
  • User-friendly
  • Instant 3D data collection
  • Data is displayed in simple planview on a high-resolution, color screen
  • Locate and mark targets quickly with innovative backup cursor feature
  • Rugged handcart-based system that is lightweight and simple to transport
  • Easy data transfer to flash card
  • No site hazards or need to close off work areas as with radiography (X-Ray)
  • Durable components that have been tested in the world’s toughest field conditions
  • Varied data collection pad sizes offer maximum flexibility
  • Affordable, turnkey solution
  • 2-year warranty
