Description

Cross Hole Ultrasonic Monitor (CHUM)

The Cross Hole Ultrasonic Monitor (CHUM) is a high-precision instrument designed for evaluating the integrity and uniformity of deep foundation elements using the Cross Hole Sonic Logging (CSL) method. CHUM delivers accurate, non-destructive assessment of drilled shafts, bored piles, and diaphragm walls by measuring ultrasonic pulse velocities between multiple access tubes embedded in concrete.

Equipped with advanced transducers and intelligent acquisition software, the CHUM system identifies critical defects such as voids, honeycombing, inclusions, and variations in concrete quality. Its real-time waveform visualization, automated data logging, and comprehensive analysis tools ensure highly reliable results even in complex site conditions.

Built for efficiency and portability, CHUM enables engineers to perform rapid integrity testing with minimal setup time, making it ideal for construction quality assurance, large-scale infrastructure projects, and routine structural evaluations.
