Concrete Block Retaining Walls
We excavate to firm bearing and pour a reinforced footing with starter bars standing proud of it. The blocks thread down over those bars course by course, horizontal steel ties in as the wall rises, then.

Concrete and Block Retaining Walls in Lower Hutt
Top Retaining Walls Lower Hutt builds concrete retaining walls across Lower Hutt. That covers segmental block systems like Keystone, steel post and concrete sleeper walls, and poured reinforced concrete for the jobs carrying real load. Concrete costs more up front than timber and then stops costing you anything at all.
- Block walls to 1m without engineering, higher with geogrid
- Steel post and concrete sleeper walls for tight side boundaries
- Poured reinforced walls where a driveway sits above
- Drainage on every wall300mm of metal, a drain coil and geotextile. Never an optional extra.
- H5 poles as standardThe right treatment for timber that lives in wet ground.
- Consents handledHutt City, Upper Hutt and Wellington, start to finish.

Concrete and Block Retaining Walls
Concrete and Block Retaining Walls we build in Lower Hutt
Concrete becomes the obvious answer the moment something sits above the wall. A driveway, a garage slab, a neighbour's fill or a pool all push extra load through the soil onto the back of the wall, and that sustained load is exactly what timber handles worst over time.
There is a second reason it turns up so often here. Wellington sits on a plate boundary and the Wellington Fault runs along the western edge of this valley. Any wall an engineer designs in the Hutt carries a seismic case as well as a static one, and reinforced concrete takes that design cleanly.
Keystone Retaining Walls
Each Compac III block drops onto pins set in the course below, and the pin position sets the setback automatically. The wall leans back about 8 degrees as it rises, putting the mass of the blocks to work.

The posts are hot dip galvanised steel with a channel down each side. We set them in concrete footings, then slide reinforced panels down the channels one at a time. Soil pushes the panel into the.

Poured concrete goes in when a building sits above the wall, when a driveway runs along the top, or when an engineer wants one monolithic structure instead of stacked units. It is also the usual answer.

The first stretcher course sits on a concrete foundation or a compacted base, set to establish the batter. Headers and stretchers then alternate up the wall forming open cells, and we backfill each layer.

The part you never see
How we build a retaining wall that drains
Nearly every failed wall we get called to in the Hutt Valley failed the same way. Water sat behind it, the soil got heavy, and the wall leaned out a little more each winter. So we build the drainage first and the face second.
- At least 300mm of clean free draining metal sits behind the wall face
- A perforated drain coil runs the full length at the base
- Geotextile cloth wraps the top and back so silt cannot block it
- The coil discharges to daylight or to stormwater, never a dead end
