Verify Concrete Slab Thickness & Integrity
No Coring —No Drilling — No Excavating

The CTG-2 is a hand-held, battery powered, nondestructive system for measuring the thickness and integrity of concrete slabs, pavements, tunnel linings, walls and other plate-like structures using the IMPACT ECHO principle.

Requires no special knowledge or training — connect the CTG-2 to your laptop or tablet* and start testing with Olson's WinCTG2 software. For greater accuracy, simply calibrate the CTG by testing a point of known concrete thickness to obtain the concrete velocity for that job.

Training

Hands-on training classes are available for all of our NDE test methods at our Wheat Ridge, Colorado (USA) location, which is a suburb located appromately 15 minutes northwest of downtown Denver. Training may be available at your location by one of our agents upon special arrangement.
