We provide an onsite rapid emergency response service to ensure clients’ and customers’ essential infrastructure returns to regular operation after disruption. Our team are there for you when projects demand agility and creative problem solving to restore vital assets to safety and productivity.

Emergency Response

GSI provides design/build geohazard repairs after a no-cost, no-obligation visit by an engineer or representative to your site.

Landslide & Slope Stabilisation

Our engineers use the most cutting-edge limit equilibrium and finite element analysis programs to evaluate slope stability.

Rockfall Mitigation

GSI offers a comprehensive suite of rockfall mitigation services tailored to address the specific needs of our clients.

Difficult Access Solutions

At GSI, we specialise in rope access techniques to safely and efficiently reach steep, remote, or otherwise challenging sites.

Ground Engineering

Our ground engineering expertise means we can undertake initial assessments and make recommendations before we begin to design tailored solutions to fit whatever conditions the site and project demands. Whatever outcome you require of the ground – we can make sure the solution is stable, fit for purpose, signed off and built to last.

In-Situ Trench Mixing (ITM)

In-Situ Trench Mixing (ITM) is an innovative ground improvement technique that uses continuous in situ soil mixing to construct strong, uniform trench walls.

In-Situ Mass Stabilisation (IMS)

In-Situ Mass Stabilisation (IMS) is a proven ground improvement technique used to treat and strengthen soft or unstable soils to depths of up to 5.5 metres.

Deep Soil Mixing (DSM)

Deep Soil Mixing (DSM) is a specialised ground improvement process that strengthens weak or compressible soils by mechanically blending in-situ material with a cementitious binder.

Jet Grouting

Jet Grouting is a specialist ground improvement technique that strengthens and seals the ground by injecting high-pressure cement grout to form solid, durable soilcrete columns.

Continuous Flight Auger (CFA) Piling

CFA piling is an efficient and low-vibration foundation solution ideal for a wide range of soil conditions and sensitive environments.

Specialist Grouting

Foamed Concrete

Foamed concrete is GSI’s specialised lightweight cementitious fill, designed for safe, efficient, and cost-effective filling of abandoned or redundant underground infrastructure.

Polyurethane Grouting

GSI’s polyurethane grouting provides a fast, non-disruptive solution for lifting and re-leveling buildings, concrete slabs, and pavements while stabilising weak or subsiding ground.
