Radar investigation and diagnosis of historic masonry
Preservation and rehabilitation of historic buildings can be successfully accomplished only if the diagnosis of the state of damage of the construction has been carefully carried out. Among the investigation techniques and procedures which have been proposed in these last years, georadar seems from one hand to be most promising, from the other to need a great deal more of study and research. The interpretation of the radar data involves the identification of significant anomalies or geometrical features. It should be a recognition process detecting features on the records that are characteristic of known signatures. Identifiable features on a radar record are continuous reflections from layers or diffractions from discontinuities like voids and local non homogeneities in the masonry. The paper discusses the most recent advancements of the GPR technology and their impact on the effectiveness of masonry investigations. Some typical problems solved by the authors with the use of GPR and a combination of other techniques such as boroscopy, flat-jack, sonic tests, thermography and others are also described; the research was carried out on several historic buildings. In the meantime the authors will also show the limits of the GPR in some applications. The aim of this contribution is also to help in giving guidelines for the choice of an appropriate use of GPR tools in the solution of various problems.
