Wisconsin Bridge Deck Surveys

Infrasense’s bridge deck survey work is “heating up” in Wisconsin as we are now focusing on this year’s infrared thermography (IR) scanning to map areas of rebar-level delamination. We also collect high-resolution visual (HRV) imaging in order to differential surface from subsurface features/ defects. Here’s our survey vehicle and some sample data showing side-by-side IR…

Infrasense and BDI Perform Ground Penetrating Radar (GPR) and Half Cell Potential (HCP) Surveys on Bridge in Norfolk, Virginia

Infrasense and BDI mobilized to Norfolk, Virginia to complete testing on the 1800-foot long bridge deck. The methods of testing included GPR, HCP, coring, and chloride sampling. Testing was performed in September on 14 select panels of the bridge deck, with the goal of identifying rebar depth and spacing, and areas of probable corrosion. The…

Infrasense Performs Ground Penetrating Radar Survey on Multiple Roadways in Virginia Beach

Infrasense completed a non-destructive survey of two intersecting multilane roadways in Virginia Beach, VA. The survey provided the client with subsurface pavement structure data along all driving lanes, shoulder lines, and turn lanes within the project section. Pavement layer thicknesses were plotted to produce a complete profile of the pavement structure. The profiles and layer…
