Results
Slope stabilised to 100-year design life standard.
Vegetation successfully regenerated without hydroseeding.
Public pathway reinstated with durable structures over the landslide escarpment.
Enhanced slope resilience and improved safety for the community.
Project
Solution
Installation of Glass Fibre Reinforced Plastic (GFRP) soil nails.
Use of Geobrugg high-tensile stainless steel rockfall netting and erosion control matting.
Natural regeneration of vegetation to reduce superficial failure risk.
Reconstruction of public access with a concrete pathway on micropiles and a timber bridge.
Project
Challenges
Landslide affecting a public walking track in a high-visibility location.
Requirement for a 100-year design life in a coastal and bushfire-prone environment.
Need to regenerate vegetation naturally without hydroseeding.
Integration of slope stabilisation with public pathway reconstruction.
Project
Overview
Following a shallow landslide across a public walking track between Wye River and Separation Creek, a slope stabilisation and pathway reconstruction project was undertaken.
The design was required to achieve a 100-year design life in a coastal, bushfire-prone environment, while regenerating vegetation to minimise future superficial failures. Works combined soil nails, stainless steel netting, erosion control matting, and pathway reconstruction, with strong public interest in both safety and environmental outcomes.
