In this research, a methodology is proposed to detect voids and measure thicknesses in typical concrete specimens in buildings. To develop this methodology, beams and concrete walls with voids represented by expanded polystyrene elements and hollow plastic or cardboard elements were made. Ultrasonic and ultrasonic pulse-echo equipment were used to scan and locate these elements, as well as measure the thickness of the specimens made of concrete. The dimensions of the simulated voids are very close to the length of the ultrasound waves, so post-processing of the data obtained was performed to improve the results of this research.
