Critical analysis of restoration practices against rising damp

The restoration of architectural heritage from rising damp is a complex technical and scientific challenge. The paper illustrates a comprehensive approach to address this issue. It highlights critical information gaps and specific topics that need further investigation in the state of the art and current practices. The research methodology adopts a multidisciplinary and holistic approach to the restoration process with the integration of historical investigation, knowledge of building elements and materials, non-invasive diagnostics for identifying degradation phenomena, methods and materials for restoration, and long-term monitoring. The research activity is part of a broader project aimed at establishing operational protocols with advanced technologies for the planned and preventive maintenance of architectural heritage. The outcome will be a digital platform, an open-access tool to support integrated building design and conservation, ensuring sustainable conservation practices to managing rising damp and related issues. The paper focuses on the restoration processes of two significant case studies: the Church of San Gennaro in Capannori (Lucca) and the Church of San Giuseppe in Rosate (Milano). The research results provide valuable insights into the effectiveness and durability of different intervention methods. Moreover, the critical analysis facilitates the choice of best practices for sustainable building heritage conservation.
