Our Solutions

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.The CSL (Cross Sonic Logging) method allows us to determine the structural integrity and homogeneity of concrete within diaphragm walls, bored piles, drilled shafts, barrettes, concrete piles, or auger cast piles. The CSL method requires a transmitter and a receiver to be inserted in parallel water-filled tubes down the pile depth to propagate and measure the speed of ultrasonic pulses. Sonitec systems have been designed for the sole purpose of facilitating the assembly and installation of long tube lengths in reinforcement cages. Sonitec 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.

Compact mini-pile system based on FT bars

Also known as minipiles, micropiles are deep foundation elements made of high-strength, small-diameter steel casing and/or threaded bars. Micropiles can be used as a temporary or a permanent solution. They can work in tension, compression, or both. This page focuses on the Geotec Micropile systems, which are based on high-performance fully threaded steel bars. If your project plans on using cages of standard rebar for micro piles instead of high-performance steel, please refer to our Rebar Coupler system page for more information on thread and coupler systems.
