BWM Sonic Pipe Solution
BWM Sonic pipe solution is a tube solution invented to facilitate the integrity testing of foundations using the CSL testing method. CSL (Cross Sonic Logging) method allows determining the integrity that is structural homogeneity of concrete within diaphragm walls, barrettes, drilled shafts, bored piles, auger cast piles or concrete piles. CSL method requires a transmitter and a receiver to be inserted in a parallel water-filled tube down the pile depth to be able to propagate and measure the speed of ultrasonic pulses.
This method has been designed for sole purpose of installation and assembling of long tube lengths in reinforcement cages. It has been for over two decades the preferred solution of piling and general contractors worldwide to safely and quickly deliver a CSL testing that is certainly meant for a perfect environment.
