Foundation Test Gauge (FTG)

Measure Foundation Depth and Integrity
No Coring —No Drilling — No Excavating

The Foundation Test Gauge (FTG) is a small laptop or tablet powered, nondestructive system for measuring the depth and integrity of drilled shafts, driven piles, concrete mats, and timber foundations using the SONIC ECHO principle (also called Pile Integrity Testing or PIT, Low Strain Integrity, and other names).

Requires only minimal training for use — connect the FTG to your laptop or tablet and start testing with Olson's FTG software. The system includes everything you need for testing except for a user-provided Windows 7 - 10 laptop or tablet - including an accelerometer receiver and a non-instrumented hammer.

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 approximately 15 minutes northwest of downtown Denver. Training may be available at your location by one of our agents upon special arrangement.
