Cross Hole Ultrasonic Logging (CHUM) / Cross Hole Ultrasonic Monitor is a specialized non-destructive testing method used to evaluate the integrity and quality of deep foundation piles. In this technique, ultrasonic pulses are transmitted between embedded access tubes in the pile, and the received signals are analyzed to detect defects such as voids, cracks, honeycombing, and poorly compacted concrete. It provides highly accurate internal profiling of piles, ensuring structural safety and quality assurance in large infrastructure projects.
