In March of 2022, the Terra Monitoring team set out to conduct annual maintenance of the settlement cells and seepage weirs in Eswatini at the well-known Maguga Dam. A Settlement Cell is a device installed in embarkments, fills and foundation soil to monitor settlement which determines the stability of a structure at an installation point. A settlement cell consists of three co ...

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
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.

Let's Talk About CPTu
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 ...
Piezometer Installations in South Africa
In late 2021, the Geomech Africa team was assigned the task of installing piezometers at two mine sites in the northern provinces in South Africa. The aim of the project was to install 83 standpipe piezometers at new and existing locations. The client needed these piezometers installed, in order for the engineers to gather important water level data for analysing the tailings d ...
