INTEGRATION OF EFD, MRM AND IRT FOR MOISTURE MAPPING ON HISTORIC MASONRY: STUDY CASES IN NORTHERN ITALY

Among the innovative techniques for detecting moisture on the historical masonry, EFD (Evanescent Field Dielectrometry) presents a high potential for providing the absolute measure of the water content, to map the salts distribution on the surfaces, without requiring to sample the materials under investigation. The integration with IRT (Infrared Thermography) results particularly useful on stone/cobbles solid masonry, because of the least reliability of the gravimetric tests on this type of wall, especially on samples collected from the layers beneath the surface. The paper presents the results on two historical buildings located in Lombardy, and the discussion regarding advantages and limits of the application: the Royal Villa in Monza and the church of Saint Ignacious in Ponte (SO).
