GPR Scanning For Concrete Footing
Ground penetrating radar (GPR) has many applications. One of its applications in engineering is to delineate lateral extents of footings for bridges, buildings and other structures. Design and as-built plans are not always available when needed and a GPR survey could provide valuable information about the footings in a non-destructive and efficient way.
The GPR profile below shows a concrete footing with reinforcement. The top of the footing was about 3' underneath a concrete floor. The GPR profile was collected next to a steel supporting structure.
