CHUM Cross Hole Ultra Sonic Monitor (CSL Tester) W

Piletest™s GPC is the next generation of dynamic pile testing systems. It is designed with simplified software and higher ease of use than past systems. The GPC system was designed with Professor George G. Goble, the pioneer of dynamic pile analyzers. The GPC complies with ASTM D4945 - Standard Test Method for High-Strain Dynamic Testing of Deep Foundations and Eurocode EN ISO-22477-4.

The CHUM (Cross Hole Ultrasonic Monitor) uses the Crosshole Sonic Logging, CSL testing method to perform high-resolution quality control of deep foundations. he system uses an ultrasonic 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 concrete quality.
