ROCKY VALLEY LANDSLIDE
Bogong
This is a rock fall above a telemetry station. Black Geotechnical were engaged to conduct a slope stability assessment, via abseil where required. The mechanism of landslide was found to be a dead tree falling over, in strong winds, dislodging a loose rock stack at its base. A landslide risk assessment was conducted and allowed recommendations to be given for slope descaling, which would allow the client's staff to have access to the telemetry station.
Cape Horn landslide
Loch, Victoria
This is a large (4.5 Ha) established landslide in the Cretaceous period sedimentary rock and residual clay. The most recent landslide movement had left steep scarps against the road. Black Geotechnical were engaged to conduct a slope stability assessment. The mechanisms of the landslide movement were identified, which enabled remediation options to be provided to the client. A combination of temporary remediation options were adopted by the client, consisting of surface and groundwater improvements together with local grading of steep slopes.
