Sonitec is a tube solution invented to facilitate the integrity testing of foundations using the CSL testing method.
CSL (Cross Sonic Logging) method allows to determine the structural integrity and homogeneity of concrete within diaphragm walls, bored piles, drilled shafts, barrettes, concrete piles or augercast piles. The method requires a transmitter and a receiver to be inserted in parallel water-filled tube down the pile depth in order to propagate and measure the speed of ultrasonic pulses.

Sonitec system have been designed for the sole purpose of facilitating the assembly and installation of long tube lengths in reinforcement cages. It has been for more than 20 years the preferred solution of piling and general contractors worldwide to safely and quickly deliver a perfect CSL testing environment.
