Geotechnical Investigations

Electronic vane shear testing (eVST) is an in-situ geotechnical method used to determine the undrained and remoulded shear strength of cohesive soils such as soft clays, silts, and cohesive mine tailings. It provides a rapid, low-disturbance alternative to laboratory testing, making it valuable for foundation design, slope stability analysis, and geotechnical site characterisat ...

Geomechanics was tasked with conducting Cone Penetration Testing (CPTu) at a mine, located about 60 kilometres north of Lilongwe, Malawi.
