NDE of masonry structures: use of radar tests for the characterisation of stone masonries

Ground penetrating radar is being used as a survey tool to study stone and brick masonries. The aim of the research is to produce guidelines for a technical procedure for the acquisition and interpretation of radar traces to detect inclusions, voids and other defects, the effectiveness of repair, the characteristics of leaves in multiple-leaf walls and to find the presence of moisture in a stone masonry wall. This paper shows first results of in situ tests carried out on historic buildings.
