Concrete retaining walls across Canberra, with drainage built in behind each one and footings sized to suit. Engineered where the height needs it.
Concrete Retaining Walls in Canberra hold back soil, create usable flat areas and protect your property from erosion and movement. A well-built wall combines strength, drainage and neat finishing, so your garden, driveway or building site stays stable for many years. Good engineering and drainage keep your wall performing reliably. Tell us the wall height and your site plans, and we will discuss footings, reinforcement, drainage and engineering requirements. Canberra's sloping blocks, clay soils and storms make drainage essential, so careful excavation and curing help walls in Tuggeranong, Weston Creek and Gungahlin resist movement. Expect a wall built to last.

Retaining walls for clay soils and sloping blocks, with proper drainage behind every single one.
Even a knee-high wall holding a garden bed needs drainage behind it. We build that in, so wet clay doesn't slowly push it forward.
When your wall needs to hold back serious height or a driveway above, we build it to an engineer's design, footings and steel included.
Rather than one towering wall, a series of lower walls stepping down your slope is often stronger, cheaper and gives you usable garden levels.
Building near the fence line? We work through neighbour agreements and ACT approvals with you before a single shovel hits the ground.
On steep blocks around Tuggeranong and Weston Creek, we step the footings to follow the rock and ground, so your wall sits on solid bearing.
Is your wall leaning or cracking? It's usually trapped water. We work out why it's failing, then repair or rebuild it properly.
We sort out height and drainage first, since together they decide whether your wall is straightforward or needs engineering. Past a certain height, or near a boundary, a wall needs an engineer and ACT building approval, and we'll tell you where your job falls before we quote, not halfway through. The soil being held back is as important as the wall itself: wet reactive clay is heavy, and that weight is the true load. We set out and dig the footings, build the wall and its steel to the design, then put in drainage and backfill in the proper sequence.
We measure how much ground is being held, look at the soil and any surcharge, and tell you if you'll need an engineer and building approval.
We mark the wall on the agreed line, then dig footings to the depth and width in the design.
We pour the footing, then build or pour the wall with its steel as designed and starter bars properly tied.
An ag drain and free-draining gravel go in behind the wall, then we tidy up and walk it with you.
The best wall for you depends on your site, your budget and the look you're after. Here's a quick guide to the most common options and where each one works best.
Sandstone and stone block walls are a favourite on sloping blocks and properties backing onto bushland, where the natural texture sits comfortably in the landscape. They're strong and long-lasting too, coping well with frost, moisture and moving clay. Pick stone if you want a wall that looks like it's always been there.
On sloping blocks or where you need a taller wall at home, concrete sleepers are tough to top. Slotted between steel posts, they give real structural strength and need almost no upkeep. They're a practical choice when the wall has to carry genuine load without demanding attention every year.
Treated pine or hardwood sleepers and logs are still popular because they're affordable and look natural. They suit smaller garden and landscaping jobs, but keep in mind timber usually won't last as long as stone or concrete, particularly where the ground stays damp.
If you need to carry heavy loads or want a crisp, modern look, interlocking concrete blocks are a great fit. Modular and core-filled systems give strong structural performance with a contemporary style that works on new homes and commercial sites.
Rock and gabion walls work well for erosion control and specialist landscaping. They use either natural boulders like granite or sandstone, or steel mesh cages filled with stone, which lets water drain through while giving your property a rugged, natural feel.
The right wall comes down to your slope, soil, budget and the style of your home. We can look at your site and suggest the option that best balances strength, cost and looks for your situation.
Nearly every failed wall we get called out to had drainage that wasn't working. That's really all there is to it.
Ag pipe and free-draining gravel go behind every wall we build, low ones included. It costs the least and matters the most.
If the height or load above needs an engineer and approval, we tell you, rather than quietly building something too light.
Footing size and steel chosen for the wall's height and what it's holding back, not a one-size detail.
We raise neighbour and approval questions on boundary walls before we start, not halfway through.
If two shorter walls would beat one tall one, we'll say so, even though it means a smaller job for us.
Every wall carries seven years' cover: if our workmanship fails, we fix it at our cost.
Quick answers to what Canberra homeowners usually ask us before getting a price.
Usually, once a wall passes a certain height or sits near a boundary, and it'll often need engineering too. We'll tell you whether your wall needs approval before we quote, not after.
Because the wall is really holding back wet soil, and soaked clay weighs far more than dry. We lay the drainage and backfill in the right sequence; leaving it out is the number one reason walls fail.
It comes down to your soil, any load above the wall and the design. We sort out height and drainage first, since together they decide whether it's a simple build or an engineered one.
Many decades, provided the footing, steel and drainage are done properly. When walls fail early, it's nearly always the drainage or a footing that was too small, not the wall itself.
Sometimes, though it involves setback rules, your neighbour's agreement and often an engineer. It's worth checking before you design the garden around it.
