GSSI StructureScan Pro GPR


StructureScan Pro is a versatile concrete inspection system offering a wide variety of antenna options for concrete and other applications.



Based on the SIR 4000 controller, the GSSI StructureScan Pro GPR provides the GPR professional with solutions to any scanning situation, typically used to:

  • Scan for rebar, post tension, conduits, and non-metallic objects
  • Concrete slab scanning
  • Locate voids
  • Concrete imaging
  • Condition assessment
  • Structural inspection

GSSI StructureScan Pro GPR Features:

Locate Targets

  • Locate rebar, post-tension cables, conduits (PVC and metal)
  • Conduct real tie surveys for core clearance or post process data for reports
  • Reach depths of 0-18 inches

Customizable System

  • Antenna choices include the popular 1600 MHz and the high-resolution 2600 MHz antenna

Premium Mobility
