Results
Successfully stabilised multiple cut slopes along the 27km motorway corridor.
Delivered a three-year program safely and to schedule, despite variable geology and access limitations.
Provided resilience in a seismically active environment with long-term ground stability.
Demonstrated capacity to scale operations, adapt methods, and maintain production continuity on a nationally significant infrastructure project.
Project
Solution
Established a fully equipped compound with covered workshop, offices, spare parts, and tooling to maximise uptime and productivity.
Core team of 30+ personnel onsite, with additional night shifts introduced when required to support production demands.
Deployed up to 7 drilling rigs, 2 robotic shotcrete pumps, and 2 high-reach EWPs for large-scale operations.
Installed tens of thousands of soil nails and rock bolts, with inclined drains drilled and cased up to 50m into fractured rock.
Constructed active Geobrugg mesh systems across steep cut slopes.
Applied more than 25,000m² of shotcrete for slope stabilisation in critical areas.
Project
Challenges
Seismically active corridor with multiple fault and thrust zones through highly fractured ground.
Steep gully alignments and saddle line crossings requiring large-scale stabilisation.
Program-critical integration with bulk earthworks contractors.
Need to maintain high production rates despite constrained and difficult access.
Requirement to scale up workforce and equipment in response to changing conditions.
Project
Overview
A new 27km four-lane motorway was constructed through steep and geologically complex terrain, requiring substantial ground engineering to manage fractured rock, multiple fault zones, and seismic risk. The CPB HEB Joint Venture awarded Geovert the major slope stabilisation package, spanning a three-year program.
Works involved large-scale soil nailing, rock bolting, mesh systems, and shotcrete, supported by a fully resourced onsite compound to ensure continuous production and flexible responses to ground and access challenges.
