The New Titan TG-150 CPTu Rig

With control and mobility in mind, the Titan TG-150 was specifically designed for reinforced testing. Mounted to a Mercedes Axor, this customisation allows the truck to act as a counterweight that prevents the rig from lifting mid-test and provides the reaction force needed to offset the 190kN of thrust applied while advancing the CPTu probe and rods at a constant 2cm per secon ...

About Sonic Drilling & Its Benefits

The Sonic rig bores 2-3 times faster (depending on soil conditions) without using any drilling mud and is able to provide continuous core samples to depths of more than 100 meters. As a result, sonic drilling can be employed in many applications including geotechnical and geothermal projects, environmental investigations and mineral exploration.

Sonic drilling can be employe...

The mechanical device was replaced with an electrical probe in the 1960s allowing the user to continuously measure the soil properties. Since the 1970s, many useful additi ...
