Abstract

The rectory of Santa Maria di Vezzolano in Albugnano (Asti, Italy) has recently been the subject of a restoration project aimed at solving the deterioration involving the external walls and in particular the main façade. In order to support the plan of restoration project, geophysical and chemical investigations were carried out with the aim of investigating and understanding the causes of decay phenomena. The diagnostic campaign was aimed at documenting the water paths and at understanding which saline species were formed as a result of the progress of the degradation, understanding their origin (linked to capillary rising phenomena and consequent dissolution of constituent and/or restoration materials). Salts migration and consequently stone material erosion were correlated with the evidence provided by non-invasive techniques: the presence of water in the internal walls detectable in IR thermography, and in the subsoil, detectable by geoelectric investigation.
