Situación inicial

The Wollongong Escarpment Area in Wollongong New South Wales is unstable and Bulli Pass is subject to rockslides especially in times of heavy rainfall. Bulli Pass has a history of slip and rock fall events. A major slip in 2008 required slope stabilisation works with the road being closed for seven weeks. Following several events, including a serious rock fall that landed on a vehicle in 2015, there have been extensive investigations into the upslope section of Bulli Pass.  After detailed analysis Geobrugg Australia was chosen as the preferred supplier of a Rock Fall and Landslide mitigation system.


The project reduces the residual slope risk profile from landslide and rock fall events. The project consisted of a 1.1 km of SL-150 Shallow Landslide Barrier and a combination of VX and UX flood debris catchment nets.  The system now provides rock fall and landslide protection from a road that has 14'000 car movements a day.  The barrier is 3.5 m high including over 1'000 rock nail anchors constructed in difficult terrain. The Barrier is also capable of containing a 500 kg rock travelling at 160 km/hour.
