The advantages : Sonic transparency

Rincent ND Technologies’ sonic transparency auscultation equipment and analysis software comply with European standard NF P94-160-1.

Sonic transparency testing of a concrete foundation element, fitted with at least two parallel steel tubes, consists of :

  • emit an ultrasonic pulse through a probe lowered into a tube filled with water, which propagates through the concrete of the foundation element.

  • use a second probe to pick up the signal in another tube, also filled with water, at the same level;

  • measure the full height of the tubes and record the ultrasonic signal travel time between the two probes, as well as the amplitude of the received signal.
