Concrete sleeper walls
Our main event. Plain grey concrete sleepers in galvanised posts. Strong, clean and low maintenance for garden terraces, driveways, cut-and-fill blocks and boundary walls.
Concrete sleeper retaining walls
The wall that holds the yard together
A retaining wall is doing a job every single day: holding back tonnes of soil and everything the rain puts behind it. That is why we build ours out of concrete. Steel-reinforced concrete sleepers slot into galvanised steel posts that are drilled deep and set in concrete footings, so the wall is anchored below the ground, not just sitting on it.
Behind the wall we lay ag-drain and drainage gravel, so water moves through and away instead of pushing on the sleepers. It is the part nobody sees and the reason the wall is still straight in twenty years.
- Steel-reinforced concrete sleepers that will not rot or warp
- Galvanised steel posts, drilled with our own auger and set in concrete
- Ag-drain and drainage gravel behind every wall
- Plain grey or timber-look finishes
Built with our own machineMini excavator and auger on every wall job, so we are not waiting on hire gear.
Retaining wall options
Concrete sleeper first, but we build the wall that suits your block, your budget and the look you want.
Timber-look concrete sleepers
The warmth of timber with none of the rot. Textured, coloured concrete sleepers that look like hardwood and last like concrete.
Timber sleeper walls
Treated pine sleeper walls for lower walls, garden edges and budgets where timber makes sense. Built with the same care: proper posts, proper drainage.
Wall and fence together
Need privacy on top of a level change? We build the retaining wall and run the fence straight up from it, in the one job, with the one crew.
Garden beds and low walls
Low sleeper walls that turn a slope into usable garden, edge a lawn or frame a pool area. Small walls get the same footings and drainage as big ones.
Replacing failed walls
Old timber wall leaning, rotting or collapsed? We pull it out, take it away and rebuild in concrete so you are not doing it again.
Heights, engineering and approvals
We tell you what applies to your block, upfront
As a general rule in Queensland, retaining walls under one metre that are clear of buildings and boundaries can be built without council approval. Walls over one metre, walls close to a boundary or a building, or walls carrying a surcharge like a driveway usually need engineered drawings and building approval.
Every block is different, so we look at yours before we quote and tell you straight what is needed. If engineering is required we build to the engineer's drawings and coordinate the certification, so the wall is compliant and you are covered when you sell.
- Honest advice on whether your wall needs approval
- Built to engineered drawings where required
- Post depth, footing size and drainage matched to the wall height and soil
Behind the wall
What makes a wall last
Deep footings
Post holes drilled with our auger to the depth the wall height calls for, then posts set plumb in concrete.
Reinforced sleepers
Steel-reinforced concrete sleepers, not timber that rots from the back the day it goes in.
Drainage
Ag-drain pipe and drainage gravel behind the wall, wrapped in geofabric, so water gets out and pressure never builds.
Straight and level
String-lined, laser-levelled and checked as it goes up. A wall you want to look at, not just hide behind plants.
Retaining wall questions
How much does a concrete sleeper retaining wall cost?
It depends on the length, the height, the access and what has to come out first. Concrete sleeper walls cost more than timber up front and a lot less over their life, because you build them once. The quickest way to get a real number is a site visit: Dan will measure up and give you a written quote with no obligation.
Do I need council approval for my retaining wall?
Often not for walls under one metre that are clear of buildings and boundaries, but walls over a metre, walls near a boundary, or walls holding up a driveway or structure usually need engineering and building approval. We will tell you exactly what applies to your block when we quote.
Why concrete sleepers instead of timber?
Timber sleepers rot, warp and get eaten by termites, especially in our climate, and most timber walls are being replaced within 10 to 15 years. Concrete sleepers are steel-reinforced and do not rot, so the wall you pay for now is the wall you keep. If you like the timber look, timber-look concrete sleepers give you both.
Can you put a fence on top of the retaining wall?
Yes. We build walls and fences, so we can run the fence posts straight up from the retaining wall posts or set them behind the wall, and do the whole thing in one job.
What about drainage?
Every wall we build gets ag-drain pipe and drainage gravel behind it, wrapped in geofabric so it does not clog with soil. Water pressure is what pushes walls over, so we take it away.
How long does a retaining wall take?
Most residential walls are done in a few days once we start, depending on length, height and access. We give you a realistic timeframe with the quote and keep you posted as we go.
Can you remove my old wall?
Yes. We pull out failed timber, block or rock walls, take the material away and rebuild in concrete.
