The CHUM system

The CHUM (Cross Hole Ultrasonic Monitor) uses the Cross-hole Sonic Logging (CSL) method to perform high-resolution quality control of deep foundations.

The system uses an ultrasonic wave sent from a transmitter to a receiver pulled through water filled access tubes embedded in the concrete. The measured arrival time and energy are strongly dependent on the concrete quality

Additional methods supported by the CHUM are Single Hole Ultrasonic Testing and Tomography (2D tomography and 3D tomography).

The CHUM is fully compliant to ASTM D6760 - 14, AFNOR NF P 94-160-1 and additional standards
