Abstract
The technique of back-ventilated façades with stone panels has been used very much over the last decades. They have replaced the buildings designed with blocks or masonry. The holding technique of these panels has been usually solved by specific anchorage points, with pin, cylindrical rod, or flat bar. One of the most common injuries on these building façade is a shear failure with frustoconical shape. The aim of this research is to study the causes that led this pathology in a particular building of Valencia (Spain). This is the tourist office, built with stone panels of sandstone. We analyze the material composition, as well as cyclic and wetting–drying tests. Non-destructive techniques have many advantages, and in this research, we have used thermal imaging technology. To identify and diagnose these stone defects, we have used specifically the passive thermography, which uses the Sun’s energy to heat and cool the building materials. An early identification of pathology in the building façades can be very interesting to be able to repair or replace the panels before they are detached from the anchors.
