THE CHUM (Cross Hole UltrasonicMonitor)




THE CHUM (Cross Hole UltrasonicMonitor)

uses the Crosshole Sonic Logging(CSL) method (ATSM D6760-08) to perform high-resolution quality control on deep foundations.

The system uses an ultrasonic wave sent  from ang emitter to a receiver while both are pulled through water-filled access tubes embedded in the concrete quality.

Additional methods supported by CHUM are Single Hole Ultrasonic Testing (SHUT) and Tomography (two-and three-dimensional).
