The article presents a description and physical evaluation of a method of flaw detection of solid structures, for example, walls, pillars, and substructures, made of refractory materials and brick masonry using as an example an investigation of concrete structures. Using the method it is possible to perform flaw detection of concrete with different fillers, including porous fillers, for example, concrete claydite. This brings the subject of flaw detection of concrete close to that of flaw detection of brick masonry and structures made of refractory materials. The method is based on local excitation of standing waves across a wall by means of multiple shock pulses. The experimental data obtained confirm that standing waves are not excited once there is a definite number of defects present, i.e., a process of complete damping of the waves occurs.
