This project in the Blue Mountains is a great example of the completed result not showing the obstacles overcome to reach that point.
Geovert carried out slope stabilisation and road protection works on Bells Line of Road, near Mount Tomah last year after bushfires and further bad weather had caused multiple slips and put the road at risk. The ground conditions were a huge challenge for us here. Historical volcanic activity had left a subsurface profile with large boulders deposited across soft silt, with no predictable pattern and abrupt changes from soft ground to hard rock encountered during drilling.
Early ground characterisation and identifying what lay beneath before works started meant equipment selection, casing methodology and drilling approach were all determined well in advance, rather than in response to problems as they emerged. Our integrated approach meant both micropiling and soil nailing to secure the slip face could run concurrently while the road stayed open.
Despite some typical Blue Mountains weather extremes ranging from snowfall to over 30 degrees at times, the crew’s ability to adapt to every challenge thrown their way meant that alongside our partners at Ward Civil & Environmental Engineering, the project was delivered successfully. This was an incredible effort from everyone involved.
