Retaining Walls

Retaining Walls for Auckland's Sloped Sections

Auckland's hilly terrain means retaining walls are a practical necessity for many properties. Whether you need to stabilise a sloping section, create usable flat ground, prevent soil erosion or define a garden boundary, Amazing Fences builds retaining walls that are structurally sound and built to last.

We work with timber sleepers, treated timber poles and concrete block depending on the application, site conditions and your budget. Our walls are properly engineered with adequate drainage and backfill to ensure long-term performance - a retaining wall built without attention to drainage will fail prematurely regardless of how solid the face looks.

For walls over 1.5 metres, Auckland Council requires building consent and engineer involvement. We can advise you on the consent process and work alongside engineers and surveyors as needed.

Common Questions

Retaining Wall FAQs

Retaining walls under 1.5 metres generally do not require building consent in Auckland, provided they are not supporting a surcharge (such as a vehicle load or building). Walls over 1.5 metres, walls close to boundaries, or walls supporting significant loads require building consent and typically an engineer's design. We can advise during the site visit.
The best option depends on the height, soil conditions, access, and your budget. Timber sleepers are popular for walls up to 1.2 metres and suit garden settings well. Timber pole walls handle greater heights and loads. Concrete block is the strongest and most durable option and suits walls in exposed or high-traffic areas. We'll recommend the right solution after assessing your site.
Properly built timber retaining walls using H5-treated timber typically last 20-30 years. Concrete block walls can last 50+ years with minimal maintenance. The biggest factor in longevity is drainage - a wall with good drainage and backfill will always outlast one that isn't draining correctly.
Yes - combining a retaining wall with a fence on top is a common and practical solution for sloped boundaries. We can build a sleeper or block wall to establish the level, then fence on top of it to achieve your required height and privacy. This is often more efficient than building them separately.
A leaning retaining wall usually signals a drainage problem, post rot, or structural failure behind the face. In most cases it's more economical and safer to rebuild properly rather than attempt to push a failing wall back into position. We can assess the situation and advise whether repair or rebuild is the right call.
