Strategies for use of singular and combined NDT methods on historic masonry

Microseismic Tomographies (2-D or SST), as singular techniques, give two levels of information across the masonry structures:

- A geometrical description of the structure, putting in evidence discontinuities, cavities, layering, changes in the materials;

- Information on the elastic properties of the materials (elastic moduli)

Several multi-method strategies can be proposed by combining the microseismic tomographies with other NDT techniques. The optimal strategies vary according the problems, but typical strategies could involve Radar tomography, which can give complementary information; Impact-Echo or Ultrasounds for a more detailed shallow information; flat jack and seismic surface profiling for calibration.

The potential applications for the results of the research will be an increased know-how for the diagnostic study of historical buildings at different levels, from a preliminary screening to the design of restoration works. These NDT techniques can be used, with minimal technological adaptements, to study the vulnerability of modern buildings and in case of earthquakes.

The end-users can be found in two categories:

- Professional or companies that work on diagnostics and restoration of masonry buildings;

- The owners or the responsible authorities of historical buildings.

The innovative features of the proposed techniques provide new powerful instruments for the assessment of the actual condition of historical buildings and can constitute a factor of success for the people working in the sector of the conservation of buildings that belong to the Cultural Heritage.
