APPLICATION OF IMPACT-ECHO TECHNIQUE IN DIAGNOSES AND REPAIR OF STONE MASONRY STRUCTURES

The impact-echo technique is traditionally used to determine position of intermediate and large defects within concrete structures. In this paper, application of the impact-echo technique for assessment of bonding condition between the facing stones, mortar, and inner rubble core in stone masonry structures is discussed. In addition, results of field testing on a historic Canadian stone masonry building is presented, which illustrates the capabilities of an impact-echo system to help with evaluating the structural stability of critical components, particularly the bonding conditions and presence of voids and cavities.
