 Ultrasonic shear wave devices have been developed since 1987 in the USSR and have become one of the most effective technologies for imaging concrete. These devices use drypoint contact, DPC, transducers to generate ultrasonic shear waves which can be used to detect internal entities and structural defects within concrete. The paper provides a brief history of the development of these devices and a comprehensive assessment of their capabilities and imaging internal entities and structural defects. Data collected from concrete specimens with different built-in flaws slash defects were processed using a commonly used data processing algorithm, the synthetic aperture focusing technique SAFT and visualized. The limitations of ultrasonic shear wave techniques for concrete inspection include the need for a significant amount of time and effort for data collection.
