Our geotechnical instrumentation division designs, installs and commissions tailor-made monitoring systems, measuring crack and surface deformation, vibration and seismicity, rock mass stress, support performance and excavation deformation. Instruments are networked through robust data logging and telemetry, communicating to a control centre or office of choice, with our team providing ongoing analysis, interpretation and advice.

Backed by a seasoned multidisciplinary team of rock engineers, seismologists and geologists, OHMS has delivered projects across Africa and beyond for clients including Anglo American, Sibanye-Stillwater, Gold Fields, Glencore, De Beers and Rio Tinto.
