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.
