Buildable retaining wall solutions for residential, commercial, and infrastructure projects
Retaining walls play an important role in creating usable land, supporting slopes, and enabling successful developments. Whether you're working on a residential project or a larger infrastructure development, Viden provides practical retaining wall designs specific to your project.
We work with property owners, developers, contractors, councils, and geotechnical consultants across a wide range of projects, including residential and commercial developments, subdivisions, infrastructure, transport, education, rural, and council works.
Practical retaining wall design for New Zealand conditions
Successful retaining wall design starts with a clear understanding of site conditions, construction requirements, and long-term performance. We combine structural engineering expertise with real-world construction knowledge to deliver solutions that are safe, efficient, and buildable.
Safety and structural performance
Compliance with New Zealand standards
Seismic resilience
Long-term durability
Budget and program requirements
Construction sequencing
Supporting geotechnical and structural requirements
Every site presents its own challenges. We coordinate with geotechnical consultants to ensure our retaining wall designs respond appropriately to ground conditions, groundwater, seismic loading, slope stability, and existing or adjacent structures.
New retaining walls
From concept to construction, we deliver complete retaining wall design solutions tailored to the needs of each project:
Concept and preliminary design
Detailed design
Construction drawings
Producer Statements
Building consent documentation
Assessing existing walls
Existing structures can often be assessed, repaired, strengthened, or upgraded to extend their service life and improve performance:
Structural inspections
Condition assessments
Failure investigations
Remedial design
Strengthening solutions
Replacement recommendations
Seismic strengthening
Retaining walls in New Zealand must be designed and assessed with seismic performance in mind. We help clients understand and improve the resilience of existing structures.
Seismic assessments
Seismic retrofit design
Retaining wall strengthening
Resilience improvements
Risk reduction strategies
Choosing the right retaining wall for your site
We select retaining wall systems based on site conditions, performance requirements, and constructability to ensure the most effective solution for each project.
Timber pole walls
Reinforced concrete walls
Anchored retaining walls
Reinforced soil walls
Gabion and rock walls
Slope stabilisation structures
Coastal and erosion protection structures
We remain involved throughout construction to ensure our design is successfully delivered on site through site inspections, construction monitoring and responsive contractor support.
Construction phase support
At Viden, we combine practical engineering experience with a clear understanding of how projects are delivered on site. Whether you're planning a new retaining wall, assessing an existing structure, or looking for early advice, our team provides straightforward engineering support from concept through to construction.
