What GSI Brings to a Geohazard Emergency

When ground moves, hours matter. GSI is a fully integrated design-build team — the same engineers who assess the hazard direct the crews that fix it. That eliminates the coordination delays that cost time on emergency contracts.

01

Nationwide Coverage

GSI can mobilise to sites across New Zealand — from Northland to Fiordland — within hours of your call. We hold equipment in multiple locations and our crews are on standby around the clock.

02

In-House Equipment — No Sub-Contractor Delays

Our own fleet of specialist plant — drill rigs, grout equipment, slope protection systems — means we are never waiting on a third party when time is critical. From first call to mobilisation is a matter of hours, not days.

03

IRATA Rope Access for Difficult Terrain

Our IRATA-certified rope access crews can assess and begin stabilisation work in locations inaccessible to standard plant — no access road, no problem. Critical for rapid response on steep slopes and coastal bluffs.

04

Active Failure Experience

GSI has direct experience managing active slope failures, post-earthquake response (Kaikōura 2016), and State Highway road closure emergencies. We know how to stabilise safely — and how to communicate with NZ Transport Agency Waka Kotahi and local authorities throughout.

05

Design and Build Under One Roof

Our in-house geotechnical engineers design the solution and our crews install it. No handoffs between consultants and contractors — the team that assesses the hazard delivers the fix.

06

NZ Transport Agency Waka Kotahi Pre-Qualified

GSI is pre-qualified with NZ Transport Agency Waka Kotahi for State Highway emergency works, enabling rapid engagement without procurement delays when roads are closed and pressure to reopen is high.

Rapid Deployment

Where Others Can't Go, We Work

GSI's IRATA-certified rope access teams can reach and begin stabilisation work on vertical faces, overhanging bluffs, and steep coastal cliffs — without waiting for access infrastructure to be built. In a geohazard emergency, that capability is the difference between a two-day response and a two-week wait.

Combined with in-house drilling, shotcrete, and ground anchoring, our teams complete multi-stage emergency stabilisation from assessment to final install — without leaving site.

What We Respond To

Rockfall Events

Sudden rockfall onto roads, rail, or infrastructure — rapid scaling, netting, barrier installation, and permanent mitigation.

Slope & Landslide Failures

Active or imminent slope failures threatening roads, buildings, or critical infrastructure — emergency assessment and stabilisation.

Road Closures

State Highway and local road closures requiring urgent geotechnical assessment to restore access.

Post-Earthquake Response

Geotechnical assessment and stabilisation of earthquake-triggered slope failures, including our Kaikōura 2016 response.

Coastal & Bluff Instability

Coastal erosion and bluff instability threatening property, infrastructure, or public safety — rapid assessment and stabilisation.

Flood & Storm Damage

Slope failures and ground instability triggered by severe weather — rapid assessment and stabilisation.

Scale & Capability

From Assessment to Installation — One Team

Emergency response isn't just about getting to site quickly — it's about having the capacity to fix the problem when you arrive. GSI brings purpose-built plant, experienced crews, and in-house geotechnical engineering to every response. We don't call sub-contractors when a job gets complex.

Our fleet includes specialist drilling rigs, crane-assisted rockfall barrier installation equipment, shotcrete systems, and grout plants — all available at short notice and operated by our own crews.
