What we do:

Infrasense uses ground penetrating radar (GPR), infrared thermography (IR), and high-resolution video (HRV) to scan bridge decks at normal driving speeds and detect:

  • rebar-level delaminations
  • overlay debonding
  • corrosion-induced concrete deterioration
  • thickness of asphalt overlays
  • concrete cover over rebar
  • patching and spalling

The GPR and IR data is collected according to ASTM 6087-08 and ASTM 4788-03, using state-of-the-art technology, and triggered with a high-resolution distance encoder.

What you get:


Following data collection, an analysis is carried out using our proprietary software systems, which utilize methodologies developed through research, and supported with over 30 years of experience. The final result is a comprehensive NDE inspection report, with concrete conditions quantified and mapped. Results include:

  • plan-view condition maps showing deterioration, delamination, cracking, spalling, and patching
  • plan-view concrete cover and asphalt overlay thickness contour maps
  • CADD-compatible versions of condition maps
  • high-resolution plan-view images of entire deck surface
  • quantities provided by span, lane, or both
  • quantities provided by repair class
