Results
Slopes stabilised across three separate slip sites.
Rockfall risk significantly reduced for road users along the Great Ocean Road.
Active anchoring ensured long-term control of unstable blocks and overhangs.
Project delivered as part of a wider government resilience investment program.
Project
Solution
Full devegetation and heavy mechanical scaling to prepare slip areas.
Installation of ground anchors (7–9m depth) post-tensioned to stabilise larger unstable features.
Application of over 12,000m² of high tensile rockfall mesh to secure slopes.
Use of wagon drills for anchor installation on steep and difficult terrain.
Project
Challenges
Three significant slips across a critical section of the Great Ocean Road.
Unstable slopes with large overhangs, wedges, and block failures beyond the capacity of drape mesh.
Requirement for safe slope access and control of loose material prior to treatment.
Need to integrate active and passive systems for long-term resilience.

Project
Overview
As part of the $53 million Great Ocean Road Resilience Project, Regional Roads Victoria commissioned rock removal and stabilisation works between Lorne and Wye River. Three slips along this section required devegetation, scaling, and anchoring to manage ongoing geohazard risks.
More than 12,000m² of high tensile rockfall mesh was installed, supported by post-tensioned anchors to actively stabilise large overhangs, wedges, and block failures too substantial for drape mesh alone.
