NDTs in the monitoring and preservation of historical architectural surfaces

Diagnosis and post intervention monitoring are central action in a new approach related to the conservation and maintenance of architectural surfaces, which takes into account not only the restoration moment, but also the behaviour of the materials over time. In this regard, ND techniques could give a significant contribution in the definition of the conservation state. This paper collects part of the authors experience in regard to NDTs used in the monitoring of historical surfaces and in the study of the transformation during CH maintenance. Furthermore, it deals with the problem of the definition of suitable indicators, taking into account the know-how of our research groups in connection to specific case studies.
