The CHUM (Cross Hole Ultra sonic Monitor) uses the Crosshole Sonic Logging (CSL) method to perform high-resolution quality control of deep foundations.
The system uses an ultra sonic 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. [ overview of this test method ] [ How to test a pile using the cross-hole ultrasonic method? ]
The CHUM is fully compliant to ASTM D6760 - 16, AFNOR NF P 94-160-1 and additional standards

"The CHUM operated perfectly in -17°c
"We just tested 4000m of CSL sections in one day!"
Unlike other systems, CHUM connects to any PC using the USB port, to form a powerful CSL system.
