Rock bolt testing

The GRANIT system provides information regarding the integrity and performance of bolts and anchorages.

The system operates by applying an impulse, axially through an impact device. The vibrational response of the bolt/anchor is captured via an accelerometer and data is transmitted to the field computer.

The system is a non-destructive method of testing; measuring the load being borne by each individual rock bolt and anchorage tested. GRANIT will also identify bolts that are broken, corroded or poorly encapsulated.
