Retaining Walls

Retaining Walls in Dunedin & Mosgiel

Dunedin is built on hills. We build reinforced concrete retaining walls that hold back the slope safely and turn unusable banks into level lawns, gardens and parking.

Built to hold, built to drain

A retaining wall is only as good as what's behind and under it. Every wall we build starts with properly sized footings and reinforcing steel, with drainage metal and a drain pipe behind the wall to relieve water pressure after heavy rain, which is the main reason walls lean or fail.

From a low garden wall to tiered terraces on a steep coastal section, we'll help you work out the right height, layout and finish. Walls over 1.5 m, or walls carrying extra load such as a driveway, need engineering and building consent, and we can help you through that process.

FAQ

Common questions

Do I need consent for a retaining wall in Dunedin?

Generally, walls retaining more than 1.5 m of ground, or any wall supporting extra load such as a driveway, building or another wall above, need building consent. Smaller walls usually don't, but they still need to be built properly. We'll tell you what applies on your site.

Why is drainage behind a retaining wall so important?

Water building up behind a wall puts enormous pressure on it, and that's the most common reason walls crack, lean or fail. We place drainage metal and a perforated pipe behind every wall to carry the water away.

How much does a retaining wall cost?

It depends on the height, length, access and whether engineering is needed. We price each wall after a free site visit, so you get an accurate, fixed quote rather than a rough guess.

Can you build steps into the wall?

Yes. We often form concrete steps and paths as part of a retaining wall job, so the whole area is finished in one go.
