Geotechnical Engineering

From slips to subdivisions: expert geotechnical reports that help you build with confidence ​

Retaining

Retaining Walls & Earthworks

Planning a retaining wall or re-shaping your site?

Our geotechnical team provides design, assessment, and certification for a wide range of retaining wall systems and earthworks across the Wellington region. Whether you need a timber pole wall for your home or a complex engineered solution for a commercial site, we can guide you through every stage: from concept design to construction monitoring.

We support homeowners, builders, and developers with retaining wall projects of most sizes and complexity, working closely with our structural team to deliver safe, practical, and council-compliant designs.

Our retaining wall and earthworks services include:

Timber pole, gabion, and concrete block wall design

Reinforced soil and engineered retaining systems

Slope cuts, fills, and site reshaping advice

Stability analysis and ground improvement recommendations

Council-ready geotechnical reports and Structural PS1 certification

Geotechnical and Seismic

Geotechnical Engineering confidence  and earthquake

As both geotechnical and seismic structural engineering specialists, we assess site-specific hazards and design foundations to perform in major earthquakes. From reclaimed land to hillside sites, our integrated approach ensures cost-effective, compliant solutions that meet council requirements and keep your project resilient.

We provide targeted geotechnical investigations to assess risk and guide foundation design, so you can build confidently even in sensitive areas.

Our earthquake-focused services include:

Site-specific seismic classification (e.g., TC1, TC2)

Ground improvement advice

Foundation recommendations for earthquake resilience

Landslips and Slope Stability

Protecting your property from slips in Wellington

Wellington’s steep terrain and high rainfall mean landslips are a constant risk, especially after storms or earthquakes. Our geotechnical engineers can assess slope stability, identify potential hazards, and design practical solutions to reduce the risk of future slips. Whether it’s for a private property, road, or development site, we use site investigations, stability modelling, and drainage design to keep your project safe.

Our geotechnical team works closely with our structural engineers, offering a one-stop shop for assessing damage, designing repairs, and providing documentation for insurance or consent.

Our landslip and stability services include:

Site inspections and geotechnical investigations after slips

Monitoring of slopes and embankments for early warning signs

Ground improvement advice

Retaining wall and slope reinforcement design

Insurance claim support and technical reporting
