Easy-to-install sonic tube system for CSL
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.
Product features
- Sonitec are based on thin black steel tubes available in different diameters and thicknesses. Our standard length is 5.80 meters.
- Instant connection. A convenient enlarged bell-mouth allows the connection of 2 tubes seamlessly, thus greatly reducing labor cost and project schedule.
- Waterproof design up to 240 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.
