Site Investigation, Bolivia
A Multitec 4000 purchased last year by an electricity company in Bolivia. The rig is being used for geotechnical work in Cochabamba, including HWL coring up to 200m, SPTs, Shelby tube sampling and lugeon tests. Compact, lightweight and mounted on tracks the rig is ideal for work in areas of difficult access, for example crossing rough terrain to access river banks
