“…Indeed, a radargram provides a distorted image of the scenario under test, which can lead to incorrect readings of the information gathered. As a consequence, there is a continuing interest in the development and use of application-oriented data-processing approaches capable of providing easily interpretable images [2][3][4]6,[13][14][15][16][17][18][19].…”

“…Regarding CH assets, GPR is useful for investigating deformation of hollow piers due to mechanical stress [3], and for studying the signal reflected by objects inside structures such as bridges or viaducts [4][5][6][7]. Moreover, it allows us to analyze the state of conservation of ancient buildings from historical, archaeological, and structural points of view [8][9][10][11][12].…”

Ground Penetrating Radar (GPR) is a flexible and cost-effective tool for performing structural integrity assessment and quick damage evaluation of manmade structures, including cultural heritage (CH) assets. In this context, this paper deals with the usefulness of GPR surveys enhanced by the use of a Microwave Tomographic data processing approach as a methodology for the diagnosis and monitoring of CH exposed to climate events and natural hazards. Specifically, the paper reports on the results of a measurement campaign carried out at the Loggia of the Consoli Palace of Gubbio (Italy). These results allowed us to increase our knowledge of the architecture of the surveyed zones and their structural hazards.

“…This is one global goal concerning the inspection. Techniques like X-rays, radar, thermography and elastic waves aim to produce ''tomograms" of the structure , Diamanti et al 2008, Ito et al 2001, Ohtsu and Alver 2009 in order for the results to be more easily understood by a general audience (owner of structure or user). For the specific case of near surface damage, the establishment of Rayleigh wave-based tomography technique is beneficial since it materializes single-side assessment, which is particularly useful for certain structures with open access only on one surface, such as tunnels and bridge deck panels.…”

“…More complex walls were also evaluated to define irregularities by means of GPR tomography [13]. Other structures, such as masonry arch bridges, were also tested in laboratory and simulated in order to define the crack size range that could be detected with GPR [14] and evaluated in different applications [15,16]. Although applications in flat walls of cultural heritage buildings have been increasing, obtaining good results (e.g., [17]), the study of columns is still a complicated issue because of the geometry of the structures, which is, in many cases, cylindrical.…”

Columns are one of the most usual supporting structures in a large number of cultural heritage buildings. However, it is difficult to obtain accurate information about their inner structure. Non-destructive testing (NDT) methodologies are usually applied, but results depend on the complexity of the column. Non-flat external surfaces and unknown and irregular internal materials complicate the interpretation of data. This work presents the study of one column by using ground-penetrating radar (GPR) combined with seismic tomography, under laboratory conditions, in order to obtain the maximum information about the structure. This column belongs to a "Modernista" building from Barcelona (Spain). These columns are built with irregular and fragmented clay bricks and mortar. The internal irregular and complex structure causes complicated 2D images, evidencing the existence of many different targets. However, 3D images provide valuable information about the presence and the state of an internal tube and show, in addition, that the column is made of uneven and broken bricks. GPR images present high correlation with seismic data and endoscopy observation carried out in situ. In conclusion, the final result of the study provides information and 3D images of damaged areas and inner structures. Comparing the different methods to the real structure of the column, the potential and limitations of GPR were evaluated.
