Concrete thickness measurement is performed by using various non destructive tests such as ultrasonic and radiography, GPS (ground penetrating radar), electromagnetic test, etc.

The most popular test is using low frequency ultrasonic energy. LMATS uses Olsen thickness gauge which is predominantly used for most of the applications in the range of 60mm to 600mm and occasionally up to 1.8m. There are several other equivalent instruments available in the industry to perform this test.     


LMATS offers concrete thickness test from Melbourne and Sydney laboratories.
