ABSTRACT

Ground Penetration Radar (GPR), thermovision and thermohygrometrics records were used to assess the conservation degree of 5 Churches located in Seville (Spain). The results were compared with the vulnerability index evaluated by DELPHI methodology in order to carry out an interlaboratory diagnosis and the validation of this multidisciplinary approach. The GPR was employed to detect structural damages on the ground floors of buildings. Thermovision was carried out to assess active dampness, while sensors of humidity and temperature were located to evaluate microclimate inside the churches. The diagnosis carried out by GPR and thermovision has not detected structural damage according to the vulnerability indexes. Infrared images do not evidence important active water movement on roofs, while vulnerability methodology allows to assess the weathering forms due to dampness by capillary and percolation, and the use of buildings. The combination of vulnerability indexes and these non-destructive technologies provide very useful results to evaluate and prioritize preventive conservation strategies.
