ABSTRACT
Engineering-geological investigations are a composite part of engineering surveys for the inspection of buildings and structures under consideration for reconstruction. Probing makes it possible to establish not only the sequence of dense / firm and weak layers and to appraise the type of soil in the geological cross-section, but also to interpret the results for assessing the physic mechanical properties of the soils. In practice, both dynamic and static probing are adopted in engineering-geological investigations. Dynamic probing is conveniently adopted in engineering-geological investigations along the periphery of the building to be reconstructed since the size of the installations precludes their placement in the basements of buildings. Inspection of the foundation material and basement walls is followed by striking them with a hammer or special instruments in order to establish the homogeneity, density and mass nature of the masonry and likewise the strength of stones, bricks or concrete.
