Piletest CHUM – Cross Hole Ultrasonic Monitor

The Piletest CHUM is a cross hole ultrasonic monitor designed for CSL testing of deep foundation elements such as drilled shafts and concrete piles.

The system enables engineers to verify pile integrity and detect structural defects within reinforced concrete foundations.

The Piletest CHUM (Cross Hole Ultrasonic Monitor) is used to perform Crosshole Sonic Logging (CSL) testing on drilled shafts and deep foundation piles.

During testing, ultrasonic transmitters and receivers are lowered into pre-installed CSL tubes within the pile. The system measures the travel time and signal strength of ultrasonic pulses passing through the concrete, allowing engineers to identify anomalies such as voids, honeycombing or poor concrete quality.

The CHUM system is widely used on infrastructure, bridge and high-rise construction projects where deep foundation elements require verification and quality control.
