A new and rapid ultrasonic pulse echo technique has been used with great effect to scan the concrete lining of two railway tunnels. The instrument used was the A 1220 from MSIA Spectrum in Russia. Working side by side two engineers from FORCE Technology were able to make a full and detailed survey of the concrete thickness and homogeneity along 1300 m of tunnel, covering an area of over 10,000 square metres in less than two months. This is an example of the advances that have recently been made in non-destructive testing of concrete and demonstrates the capability of modern technology in providing the much needed post construction checks of civil engineering structures.
