Coring on masonry elements

Mechanical coring, carried out through rig-based drilling system, allows the extraction of masonry cylindrical samples and the direct observation of the wall inner section, obtaining a clear view of the masonry composition thus verifying the presence and location of discontinuities. It is possible to carry out both core drilling on walls for the analysis of the internal composition of masonry (also using an endoscope) and for the extraction and laboratory analysis of mortar/stone/brick samples, or sub-vertical drillings to assess the foundations’ depth and nature. In case of heritage buildings, micro-coring is commonly selected, with a small external diameter (25-40 mm) and depth ranging from 0,50 to several meters, to obtain maximum information with limited disturbance.
