Results
641 soil nails installed with mesh, enabling bridge foundation works while maintaining zero environmental incidents.
Reduced time and cost, with minimal environmental impact and strong client feedback on problem-solving and collaboration.
Highly Commended at the CCNZ National Awards.

Project
Solution
Built a custom platform to safely carry a Berretta T48 drill and two-person crew - tripling drilling capacity versus wagon drilling and reducing HSE/environmental exposure.
Installed a horizontal, cantilevered silt fence along the toe to capture and allow active clearing of debris; the client requested it remain for bridge construction.
Executed the full soil-nail/mesh scope using crane-assisted access and tailored sequencing to maintain river protection.
Project
Challenges
No benching/flat ground; steep 30–40 m slopes limited traditional plant options.
Preventing debris pollution to the Waikato River with standard silt fences deemed unsuitable under load.
Working at heights and over water, with COVID restrictions adding delivery complexity.
Project
Overview
To facilitate construction of Hamilton City Council’s new Waikato Bridge, the steep riverbank required stabilisation using 641 × 8 m soil nails and mesh with strict river-protection measures. The site offered no flat working area and rose 30–40 m above water, making conventional wagon-drill/rope-access approaches slow and risky.
Geovert designed a custom access and containment methodology to lift productivity, reduce risk and safeguard the river during works.
