Sonitec: Cross Sonic Logging Tubes.

Sonitec is a tube solution invented to facilitate the integrity testing of foundations using the Cross Sonic Logging (CSL) testing method. CSL is an accurate method to determine the structural integrity and homogeneity of concrete. Testing of concrete usually occurs within diaphragm walls, bored piles, drilled shafts, barrettes, concrete piles or auger cast piles. This method requires a transmitter and a receiver to be inserted in parallel water-filled tubes at specific spacing’s. CSL then measures the propagation time and relative energy of an ultrasonic pulse between the transmitter and receiver. This information is then used to determine the structural integrity and homogeneity of the pile. For over 20 years Sonitec has been the preferred solution of piling and general contractors worldwide to safely and quickly deliver a perfect CSL testing environment.


Sonitec are based on thin black steel tubes available in different diameters and thicknesses. Our standard length is 5.80 meters.
A convenient enlarged bell-mouth allows the connection of 2 tubes seamlessly, thus greatly reducing labour cost and project schedule.
Waterproof design up to 200 meters. The PUSH-FIT system connection between the mouth and rubber gasket ensures a concrete-tight joint that will maintain the tube integrity and prevent the entry of foreign material. Our tubes are 100% verified in factory for leakage.
High loading capacity steel ears welded at regular spacing to tie and lock two tubes together.
Compliant with ASTM D6760, the standard method for integrity testing by ultrasonic cross-hole testing.
