Electronic Vane Shear Testing (eVST) is a widely used method for measuring the undrained shear strength and remoulded shear strength of soil. This technique involves pushing the apparatus into the soil and rotating it, using an electronic motor situated above the vanes, at a controlled rate while measuring the torque required to cause shear failure. eVST is a quick, easy, and n ...

Our projects often take us to locations that few people have ever seen. On high mountains, and in deep valleys.For a recent project, our teams were commissioned to conduct geotechnical drilling in an area that rarely sees the presence of any human being. Surrounded by wildlife, our teams had to build roads by breaking apart boulders and flattening them out to create access rout ...

In June 2023, Geomech Africa was awarded a project to conduct a geotechnical investigation on a collapsed dam wall at Lonehill Park and Dam in Johannesburg. After heavy rainfalls experienced in mid-2022, the pedestrian bridge and dam wall collapsed resulting in heavy water loss due to the rising water pressures.The Geomech Africa team mobilised to the site on the 10th of July 2 ...

Over the past few weeks, our teams have received extensive training on health and safety in the workplace. The OHS Act (Occupational Health and Safety) requires that staff members within the workplace are selected and legally appointed as safety representatives. It is their responsibility to monitor and assist the company in ensuring that the workplace remains safe and that any ...

First introduced by the GeoGroup as a service in 2017, MOSTAP soil sampling is a fixed-piston sampler which minimises soil disturbance and is able to obtain undisturbed samples of various diameters at any given depth. MOSTAP soil sampling involves driving a steel sampler into the ground using a standard CPT pusher rig. Once at the target depth, the MOSTAP is activated allowing ...
