Boat Cradle Design - cradles that securely support vessels, tailored to each vessel's dimensions and weight

Safety and Compliance - non-slip surfaces, emergency stops and secure locking systems

Environmental Considerations - measures to minimise disruption to coastal and marine ecosystems

We specialise in the design and construction of seawalls, breakwaters, and groynes that provide robust and sustainable coastal defence. Our solutions are tailored to New Zealand's unique coastal environments to mitigate erosion, protect shorelines, and enhance community resilience.

Seawall Design - seawalls protecting shorelines from erosion and wave action using concrete, stone or steel

Breakwater Design - breakwaters reducing wave energy to create calm waters for harbours and marinas

Groyne Design - groynes that trap sediment and stabilise beaches, reducing longshore drift

Environmental Impact Assessment - assessments of effects on local ecosystems and marine habitats

Structural Integrity and Maintenance - structures designed for long-term performance in marine environments

We provide specialised assessments to evaluate the impacts of coastal erosion and rising sea levels, offering actionable insights and strategies to mitigate risks. Our assessments are grounded in the latest scientific research and tailored to New Zealand's diverse coastal environments.

Coastal Erosion Assessments - analysing shoreline changes to predict erosion and identify vulnerable areas

Sea-Level Rise Impact Assessments - modelling sea-level rise scenarios and their impacts

Climate Change Adaptation Planning - integrating assessments into broader climate adaptation plans

Environmental and Regulatory Compliance - meeting NZ regulations and supporting sustainable coastal management

We specialise in designing effective coastal protection solutions that safeguard New Zealand's shorelines while promoting sustainability. Our designs are tailored to each site, integrating engineering expertise with environmental considerations to create resilient, adaptive coastal defences.

Seawalls and Revetments - robust structures protecting against coastal erosion and wave action

Breakwaters and Groynes - structures managing sediment movement and reducing wave energy

Beach Nourishment and Dune Restoration - rebuilding and stabilising eroded shorelines

Hybrid Solutions - combining traditional engineering with nature-based solutions such as living shorelines

Environmental Impact Assessment - assessments of effects on local ecosystems and communities

We offer comprehensive design and repair services for marinas and wharves, ensuring these structures are both functional and resilient. Our coastal engineering expertise lets us create and maintain facilities that withstand New Zealand's challenging marine environments.

Marina Design - marinas with floating docks, fuelling stations and utilities for a range of vessels
