Construction Inspection

Sonic/ultrasonic testing provides an efficient and accurate means of evaluating the internal integrity of a concrete structure that have external spalls, honey combing and cracking indicative of possible internal weaknesses. Sonic/ultrasonic data acquired with a series of crossing paths and tomographic data processing provides a graphical display of the internal results. GPR data are acquired to determine reinforcing, spacing and depth of coverage. Post repair measurements are used to verify the effectiveness of repairs.
