| Sumario: | At retrofitting of buildings or at building damages analysis, the identification of footing characteristics is of high interest. The application of GPR for determining the size, depth and characteristics of footing is usual, due to the non-invasive character of this technique, the possibility to be performed at urban environments and the relatively fast survey. In this work three different footing types are evaluated; a reinforced concrete slab, isolated footing and isolated footing over shaft foundation. The objective of the analysis is to evaluate the potential identification of the foundation size, and especially, as the construction characteristics are known, to check the identification availability of the lower foundation limit (or footing depth). The presence of inverse propagation velocity contacts at the footing base, the wave phase change related to higher reflective media in the profiles, the propagation of multiple reflections or the changes of propagation velocity between the foundation and the natural soil are the main challenges in the exact identification of the foundation characteristics |
