Project
Solution
Delivered a combination of stabilisation measures, including anchored mesh-netting, drape meshing, and downslope shotcrete applications
Introduced a pneumatic drycrete pump system allowing shotcrete application via rope access with water added at the nozzle, improving safety and productivity
Implemented continuous monitoring and robust safety protocols across all work areas
Coordinated with stakeholders to manage works while keeping traffic flowing along the highway
Project
Challenges
Widespread slope failures across multiple sites following cyclone damage
Requirement to maintain traffic access along a critical transport corridor during works
Steep terrain and downslope working areas with limited access
Urgent timeframes to stabilise slopes before further weather events
Need for safety innovations to reduce risk for rope access crews
Project
Overview
Following Cyclone Gabrielle in early 2023, the Brynderwyn Hills experienced widespread slope instability along one of Northland’s most critical transport routes. The damage created immediate safety risks for road users and raised concerns over the long-term reliability of this strategic corridor.
Over an 18-month programme, Geovert worked alongside Fulton Hogan and WSP to deliver complex slope stabilisation solutions across steep and highly constrained terrain. The works incorporated a range of long-term stabilisation measures to restore resilience, with a standout innovation being the introduction of pneumatic drycrete pump technology for downslope shotcrete application – a method that reduced manual handling for rope access crews while improving both safety and productivity.
