Save thousands of dollars on your next job by determining concrete pavement/flatwork thickness in 1-Easy Step! No drilling, no coring, and no need to excavate to determine concrete slab thickness and integrity using the Concrete Thickness Gauges (CTG™)...

The CTG™ line of concrete thickness testing instruments are nondestructive, battery-powered handheld systems for measuring the thickness and integrity of concrete slabs, pavements, tunnel linings, walls and other plate-like structures. These systems feature a handheld gauge that records thickness information, a handheld test head (shown attached to pole) for generating and receiving sound waves and a telescoping pole for use on concrete slabs or overhead.

The CTG™ requires no special knowledge or training. It reliably measures the thickness of any type of concrete using the Impact Echo (IE) principle. Use it right out of the case with built-in default concrete parameters. For even greater accuracy, the unit features a simple calibration mode to measure the concrete velocity. Simply test at a point of known concrete thickness as a calibration reference for the speed of sound in that concrete and start testing!
