Non – Invasive GPR Investigation of Spread Footings

A non-invasive GPR survey was carried out in order to investigate spread footings of reinforced concrete skeleton building with basement. The GPR survey was performed in 2D geometry around support columns using a ground coupled antenna with central frequency of 400 MHz. The processed data allow very detailed interpretation of spread footings. This type of geophysical survey confirms its suitability and usability in such non – invasive investigation.
