Geotechnical Investigations

What is Exploration Drilling?Exploration drilling is used in the mineral mining industry to probe the contents of known ore deposits or to explore sites for potential geological/commercial value. Exploration drilling allows geologists to extract and examine sample ore profiles at the surface with reduced environmental impact & lower costs as opposed to alternative methods o ...

POLIHALI TRANSFER TUNNELIn August 2021, the Geomechanics team broke ground in Lesotho for the Polihali Transfer Tunnel project. The client required Geotechnical Data for the design and construction planning of a transfer tunnel. The mandate was to conduct drilling at 4 various drill locations for core extraction, Lugeon testing, Hydrofracture testing and downhole surveying.At o ...

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 ...

WHY SONIC DRILLING
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.

CPT & CPTu Cone penetration testing or CPT is an in-situ ground investigation technique. First developed in the 1930s as a mechanical device, the aim of this device was to determine the soil stratigraphy. 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 ...
