NON DESTRUCTIVE TECHNIQUES IN THE POST-INTERVENTION: DIAGNOSIS AND MONITORING OF ARCHITECTURAL SURFACES IN BUILT CULTURAL HERITAGE .
The present contribution deals with the use of non destructive techniques (NDTs) in the assessment of the conservation state, evaluation of the intervention effectiveness and monitoring of restored historical architectural surfaces [1]. A brief review of ND methods tailored on the authors experience will be given, together with the description of some NDT applications on real case studies, in relation to selected types of decay commonly found. Furthermore, an open discussion on i) the role and the good practices for ND monitoring; ii) the problems related to the individuation of indicators and corresponding threshold values for evaluating the materials conservation state; iii) the efficacy/durability of conservative interventions are discussed. 1. Introduction In the last 30 years, conservators have become more conscious of the restoration risks linked to the incomplete assessment of the intervention effectiveness and to the use of innovative restoration materials and techniques, whose behavior and compatibility over time is not entirely known, yet. The post-intervention diagnosis and the monitoring over time have been recognized as an essential action in the conservation of the Cultural Heritage (CH). n this frame, NDTs could give a significant contribution not only in the definition of the conservation state of architectural surfaces, but also during and after maintenance and restoration interventions. The NDTs can address and reduce invasive sampling and allow an extensive evaluation of the variation of some characteristics (colour, water absorption, surface texture, cohesion, detachment, etc.) [2]. The importance of NDTs is enhanced for continuous or repeated monitoring campaigns in order to assess the restoration functionality accordingly to specific conservation questions. Throughout these campaigns, the use of invasive techniques might be however necessary but they should not be a priori choice if not supported and planned on the results obtained by NDTs. 2. Consideration about NDT and common decay in ...
