Boundary

Long runs that have to stay dead straight, usually with a fence going on top.

  • Dead straight through ground that isn't
  • Fence brackets set for the fencing contractor
  • Approvals and the neighbour stay yours

Talk to us about your wall

Six short questions, about two minutes. Your details come first, so if anything cuts out halfway we can still call you back.

What it is

The longest runs we build, and the least forgiving. A boundary wall is looked at from both sides for decades, so the line has to be dead straight through ground that isn't. There's often a fence going on top. We don't build fences, but we can put you in touch with a fencing contractor we trust. Talk to your neighbour before we start. Neighbour and boundary arrangements are yours to make, and we'd only need to speak with them if we need access through their property to build the wall.

What decides this job

Where it sits

The property that needs the wall is the one responsible for it. Check with your local council about approvals before you build.

Your neighbour

Talk to them before we start. Neighbour and boundary arrangements are yours to make, and we’d only need to speak with them if we need access through their property to build the wall.

The fence above it

We don’t build fences, but we can put you in touch with a fencing contractor we trust.

What goes in

Galvanised steel posts in pier holes drilled with the right auger for the job, 450 mm on some walls and 300 mm on others, concreted with 32 MPa concrete from the plant. Then steel reinforced concrete sleepers, with geofabric, a 100 mm socked ag pipe and 20 mm drainage gravel behind the wall.

Know roughly how long and how high? Brittany can give you an estimate over the phone.

29 people have written about what it was like, and they all write about the same things.

The thing people tell us most is that they can’t believe it’s only the two of us. After that, it’s how fast Jake works, how clean he leaves the site, and the quality of the wall.

Why people trust us with this

Long runs that have to stay dead straight, usually with a fence going on top.

The line holds

Set out with string lines, then galvanised posts concreted with 32 MPa concrete from the plant. We use the right auger for the job: 450 mm on some walls, 300 mm on others. A boundary wall is looked at from both sides for decades.

The fence sits right on top of it

We don't build fences, but we leave the wall straight and the levels right, and we can put you in touch with a fencing contractor we trust.

Your neighbour hears it from you

We don't approach neighbours. We'd only need to go through their place if that's the only way in, and you'd know before we started.

The price is locked for 30 days

The price you accept is the price you pay. It only changes if you ask for extra work during the build, and then Jake agrees it with you on site and you approve a new quote first.

Warranty on the wall and on the sleeper

A 6 year 6 month workmanship warranty from us, and 50 years on the sleeper from our supplier.

Jake builds it

The person who quotes your wall is the person who builds it, on site from about 6:30, with no crew you've never met.

Walls we've built

Some of the walls we've built, and where they are.

How a wall gets built

Most of the work is finished before a single sleeper is visible.

This is how Jake builds a knock down and rebuild, which is most of what we do. Three of the four stages are hidden the day the job's finished, which is why two quotes can look the same and be thousands apart.

  1. 01

    Old wall out, set out, holes dug

    The old wall comes down and is disposed of. Then Jake sets out, runs string lines for the heights and lengths, marks every post and drills the holes with the right auger for the job: 450 millimetres on some walls, 300 millimetres on others.

    A drilled hole gets to depth and gives the post the footing it needs. Hand dug holes often don't.

  2. 02

    Posts concreted, then left to set

    Galvanised steel posts go in and get concreted with 32 MPa concrete from the plant. Never hand mixed and never rapid set. Then the concrete's left to set before a sleeper goes anywhere near it.

    Bays run 1.6 to 2.4 metres depending on the wall.

  3. 03

    Sleepers in

    Steel reinforced concrete sleepers from a supplier who warrants them for 50 years. We don't use seconds, or sleepers light on reinforcing bar.

    The bar inside the sleeper is the one part of the wall you'll never see, and the part you're really paying for.

  4. 04

    Drainage behind the wall

    Geofabric behind every wall, a 100 millimetre socked ag pipe, and the space behind the sleepers backfilled with 20 millimetre recycled drainage gravel.

    We use 100 millimetre socked ag pipe, the size engineered walls are drawn with, even on walls that don't need engineering. Soil backfill holds water against the wall until the pressure pushes it over, which is why ours is gravel.

Jake measures it on a Saturday, and the quote you accept is locked for 30 days.

What people ask about how it’s built

We use the right auger for the job: 450 millimetres on some walls, 300 millimetres on others. The posts are concreted with 32 MPa concrete from the plant, and how deep they go depends on the wall and the ground, which Jake works out on site.

We never hand dig, hand mix or use rapid set. Those are where many failed walls went wrong, and none of it shows the day the wall is finished.

Geofabric behind every wall, a 100 millimetre socked ag pipe, and 20 millimetre recycled drainage gravel filling the space behind the sleepers.

We use 100 millimetre socked ag pipe, the size engineered walls are drawn with, even on walls that don't need engineering.

Soil holds water against the back of the wall, and that water pressure is what pushes walls over.

Gravel lets the water drop to the ag pipe and drain away. It's one of the cheapest things to leave out and one of the most expensive to put right later.

Why walls fail

Yes. The post holes still have to reach depth, so rock means rock breaking, and that adds time and cost.

If you know there's rock, tell Brittany when you call. It's priced into your quote, and once you've accepted it the price is locked.

Because a post that's loaded before its concrete has set can move, and a wall is only as straight as its posts. So the posts get concreted, the concrete's left to set, and the sleepers go in after.

It's part of why a normal wall takes two to three days rather than one.

Yes. Fence brackets fix to the wall's steel posts and the fence stands on those. The brackets go on before the top two sleepers, so tell us when you ask for the quote, not once the wall is up.

We fit the brackets as part of the wall. The fence itself is a fencer's job, and we can put you in touch with one we trust.

Fence brackets, in order

About 1100 millimetres. That's what our 1.7-tonne machine needs to get through, and it's worth measuring at your narrowest point before you call anyone.

Tight but workable access adds machine time, and hand labour if Jake has to put the sleepers in by hand, which adds cost. If the machine can't reach the wall, we can't take the job, and we'll tell you on the phone before booking a site visit.

No. We build concrete sleeper retaining walls only.

That means no turf, plants, garden beds, fencing, timber, rock or sandstone walls. We're retaining wall builders, not landscapers, and the quote covers the retaining wall.
