  • Benefits
  • Specifications

BridgeScan™ is a complete, affordable GPR system that provides an effective tool for quickly determining the condition of aging bridge decks, parking structures, balconies and other concrete structures. The system is also used to obtain accurate concrete cover depth on new structures. With BridgeScan, repair costs can be estimated correctly, saving time and money.

Typical Uses of BridgeScan Include:

  • Bridge deck condition assessment
  • Concrete cover depth on new structures
  • Concrete inspection – locate metallic and
    non-metallic targets in walls/floors
  • Measure slab thickness
  • Void detection and location
  • Inspection of other reinforced concrete structures
