Wall has been up two winters now and has not moved a bit. Rapt with it.

- Terraced walls, boundary runs and driveway walls
- Timber, block, gabion and engineered builds
- Reviews from the owners on each job
- 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 handledChristchurch City, Selwyn and Waimakariri, start to finish.
- Itemised quotesYou see what the drainage and the spoil actually cost.

Rang three companies and these were the only ones who turned up when they said they would. Ended up doing 22 metres along the back boundary. The lawn is finally flat enough for the kids to kick a ball on, which was the whole point. Would have them back tomorrow.

Our old wall was rotten right through and leaning into the neighbour's place. They pulled the lot out, put proper drainage behind the new one and had it finished in three days. Swept the site clean every afternoon before they left too. Tidiest crew we have ever had here by a long way.

Not the cheapest quote I got, but the only one where someone actually explained why the drainage mattered instead of just handing me a number. Two years on and the wall is dead straight. Money well spent and I would use them again without thinking about it.

Steep section, shocking access, and they still made it look easy. They suggested two smaller walls instead of one big one, which saved us thousands in engineering fees. The terrace in between is now my favourite part of the whole garden.

Quote turned up the next morning with everything itemised, right down to the spoil removal. No surprises at the end, which is rarer than it should be. Wall has been through a few decent southerlies already and it is not going anywhere.

The part you never see
How we build a retaining wall that drains
Nearly every failed wall we get called to in Christchurch 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
