BridgeScan - Hero
Inspect deficient bridges with GPR for quantifiable data
The BridgeScan system provides a non-destructive means to accurately assess the health of bridge decks and concrete structures.
  • BridgeScan - Feature 1

    Acquire Data

    The BridgeScan can identify areas of deterioration inside reinforced concrete bridges. This GPR system makes overlay thickness and concrete cover depth measurements easy to achieve.

  • Cost Effective Bridge Surveys

    With BridgeScan, repair costs can be estimated accurately, saving project time and money for Departments of Transportation and pavement contractors.

Data Examples
Bridge Deck Condition Assessments

After exporting processed data from RADAN, this color-coded deterioration contour map was created with DPlot® software to illustrate areas of deterioration.

Bridge Deck Condition Assessments

Data represents rebar locations of processed bridge data displayed in RADAN 7 BridgeScan module, using Interactive Interpretation mode.
