Results
Accurate data provided for VicRoads’ slope stabilisation design and analysis.
Active slip zone successfully stabilised using soil nails and mesh.
Slope face regenerated naturally without hydroseeding.
Safer, more resilient slope supporting long-term stability of the roadway.
Project
Solution
Geotechnical drilling and installation of anchors for destructive load testing.
Scaling and devegetation to prepare the slope for safe access.
Soil nails installed with GFRP bars.
High tensile Geobrugg TECCO G65 stainless steel mesh combined with erosion control matting.
Project
Challenges
Requirement for destructive anchor testing to inform global stability analysis.
Active slip zone requiring detailed geotechnical investigation.
Hazardous working conditions on an exposed slope face.
Integration of stabilisation works with environmental outcomes.
Project
Overview
Engaged by VicRoads, Fulton Hogan, and the South Western Alliance, geotechnical investigation and destructive anchor testing were undertaken to support slope stabilisation design and analysis.
Following investigations, construction works included anchor load testing, soil nailing, and installation of a TECCO mesh system with erosion control matting.
The project combined face scaling and devegetation to improve safety during installation, with GFRP soil nails and stainless steel mesh forming the long-term stabilisation system. The slope regenerated vegetation naturally, achieving stability and environmental integration without hydroseeding.
