Infrared Thermography (IRT) is a valuable and cost effective inspection method for evaluating bridge decks to detect delamination in concrete. Penetradar has improved upon current methods of infrared thermographic inspection utilizes the advances in camera technologies. These improvements streamline data collection, enhance analysis and provide greater accuracy in results.

Penetradar Technical Services Group provides infrared thermographic inspection of bridge decks with a vehicle based system that utilizes an advanced, high resolution thermographic camera and incorporates leading-edge computer based video data acquisition and image processing hardware and software, which results in improved detection rates and accuracy in the location and size of deteriorated concrete areas.

Hi-Res Wide Angle Camera

Penetradar's ThermaMap System shown above scanning a bridge deck for delamination. Delaminations can be detected by a thermal difference in the concrete. The camera's wide angle lens permits full lane infrared capture on the bridge deck. Only one pass is needed per lane.

Radiometric Data

Penetradar's state of the art ThermaMap IRT inspection system utilizes the most advanced IR camera technology. We record radiometric data, which is actual numerical temperature information for each pixel. This streamlines data collection by simplifying the calibration requirement of IR hardware and reducing data collection times. Radiometric data also lends itself to analytical and statistical post processing which is not readily possible with older infrared technology utilizing only image based outputs. This improves our accuracy and reliability of delamination detection.

Plan-view Infrared Map

Penetradar’s cutting-edge analysis software produces accurately scaled, plan-view (top-down perspective) thermal maps showing delaminations based upon distance. Our software preserves of the size, dimensions and location of thermal anomalies such as delamination, debonding or other flaws.
