Timber Pole Retaining Walls
Post holes go in about 450mm across, taken down to roughly the same measurement as the finished wall height. A 1.2m wall gets a 1.2m hole. Poles sit at 1.2m centres, we brace them plumb, then fill each.

Timber Retaining Walls in Lower Hutt
Top Retaining Walls Lower Hutt builds timber retaining walls right through the Hutt Valley, from a knee high garden step in Waterloo to a stepped 1.4m terrace on a Normandale hillside. Timber suits the flat valley floor and the gentler hill sections, it goes up fast, and it is the cheapest wall per metre we build.
- 200mm H5 poles set at 1.2m centres in concrete footings
- Drainage metal, drain coil and geotextile on every wall
- Stepped terraces where one tall wall would trigger consent
- 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.

Timber Retaining Walls
Timber Retaining Walls we build in Lower Hutt
The parts that decide how long a timber wall lasts are the parts you cannot see once it is finished. Anyone can nail a rail to a post. The wall survives because the poles carry an H5 treatment, because the footing goes deep enough into ground that actually holds, and because there is clean metal and a drain coil taking water away behind the face.
Wellington weather makes that last point sharper here than it is in most of the country. The valley catches heavy rain off the Tararua Range and the southerlies drive water into everything standing up. A drained H5 wall here commonly runs 25 to 40 years. An undrained one can be soft at ground line inside a decade.
H5 Treated Pine Retaining Walls
New Zealand grades treated timber by where it is allowed to sit. H4 covers ground contact in normal conditions, which is a fence post. H5 covers ground contact where the timber stays wet, which is exactly.

H5 posts go in at 1.2m to 1.5m centres, then heavy H4 sleepers drop down between or behind them. The sleepers stack rather than fixing individually, so the wall builds up quickly and the face stays flat.

Crib walls use H5 headers and stretchers laid in alternating tiers, a bit like a log cabin with open cells. The first stretcher course sits on a concrete foundation or a well compacted base to lock in the.

Sleepers give the cleanest lines and suit a modern garden. Pole and rail costs least per metre on a longer run. Keystone block handles curves, because segmental blocks step around a radius in a way.

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
