Perth blocks are rarely flat and almost never solid. Between the sand, the limestone shelf and the way our suburbs get carved into slopes, most homes end up needing a wall to hold something back — a driveway, a lawn, a pool surround, or a neighbour’s garden that keeps ending up on your paving after every winter.
We have been building retaining walls across Perth since 2007. Limestone block, concrete sleeper, panel-and-post — supplied, engineered where it needs to be, and installed by the same crew that quotes the job.

Anyone can stack blocks. Holding back sand for twenty years is a different problem.
Most of the Perth coastal plain is loose sand over limestone. Sand does not hold an angle. It does not drain the way clay does either — water sheets straight through it and pools at the base of whatever is in its way. That combination is why so many Perth retaining walls lean, bulge or crack within a few seasons of being built.
The walls that last do three things right:
Footings that reach something solid. In sand that often means going deeper than the wall looks like it needs. On the limestone shelf it can mean coring. Guessing the depth is the single most common reason a wall fails.
Drainage behind the wall, not just in front of it. Agricultural drain, clean aggregate backfill and a proper outlet. Water trapped behind a wall is what pushes it over — not the weight of the soil.
Compaction in layers. Backfilling a wall in one dump and walking away means the ground behind it settles for the next three years, and the wall goes with it.
None of this is visible once the job is done. That is exactly why it gets skipped.
Most retaining wall jobs come with something else attached — a fence on top, a gate through it, or a boundary that needs finishing once the levels change. We handle the lot, so you are not chasing three trades to close one gap.
Alongside retaining walls we build:
Doing the wall and the fence as one job means one crew, one quote and one site visit. Have a look at our residential fencing and commercial fencing work, or at the gates we build to match.
The right wall depends on what it has to hold back, how high it goes and what you want it to look like when it is finished. These are the systems we build across Perth.
The Perth default, and for good reason — it suits the local look, it is readily available, and a properly built limestone wall will outlast the house. Natural limestone blocks give you the rough, characterful finish common through the older northern suburbs. Reconstituted limestone gives you a cleaner, more uniform face if you want the wall to look built rather than quarried.
Best for garden terracing, driveway edges, front-yard levelling and anywhere you want the wall to read as part of the landscape rather than a structure. Limestone retaining walls Perth
Galvanised steel H-posts with concrete sleepers dropped between them. Straight lines, sharp edges, and strength that scales — you can go higher with sleepers than you can with most block systems, and they take a Colorbond fence on top cleanly.
Best for boundaries, split-level blocks, pool surrounds and anywhere the wall is doing structural work rather than decorative work.
Precast panels between posts. Fast to install, consistent finish, and cost-effective across long straight runs. Common on newer estates through Perth’s north where whole boundaries need levelling at once.
The most common job we do. A retaining wall and a boundary fence are one problem, not two — the wall height changes the fence height, the fence posts have to be set relative to the wall, and doing them as separate trades on separate visits is how you end up with a gap under your fence and a dispute with your neighbour.
We build the wall and the fence in one go. Colorbond fencing Perth
Timber retaining walls provide a practical and natural-looking option for landscaping and garden projects while still delivering reliable support and stability.
For unique landscapes or specialised retaining wall requirements, we design and build custom retaining solutions tailored to your site conditions and project goals.
Perth’s soil conditions and climate require retaining walls that are engineered for strength, drainage, and long-term durability. Our retaining wall builders use proven construction methods and high-quality materials to ensure every wall performs reliably over time.
Clients choose WA Fencing and Retaining because we provide:
We build retaining walls that are designed to perform under pressure while maintaining a professional appearance for years to come.
Six steps, in order, from the first phone call through to the last load of spoil off your verge.
We come out, look at the fall across your block, check what the soil is actually doing and work out the height and the drainage before anyone talks price.
Materials, height, length, drainage, excavation, removal of the old wall if there is one, and clean-up. One number, on paper, with a start date. No progressive surprises.
Many Perth councils require a building permit once a retaining wall goes past 500 mm high, and some want engineering drawings with it. Requirements differ between councils, so we check with yours before we book the job in rather than after.
Old wall out, ground cut to level, footings dug to depth.
Footings, wall, drainage, and backfill placed and compacted in layers.
Spoil removed, site swept, nothing left on your verge.
Homeowners, builders and businesses across Perth use WA Fencing and Retaining because the wall gets built for the ground it is actually standing in, not for the photo.
Footings to depth, drainage behind the wall and backfill compacted in layers — the parts you cannot see once the job is finished are the parts that decide how long it lasts.
We work right across Perth, with most of our work through the northern suburbs — Joondalup, Duncraig, Kingsley, Greenwood, Woodvale, Padbury, Ocean Reef, Carine, Warwick, Craigie, Heathridge, Currambine, Marmion, Balcatta, Osborne Park, Yokine, Alexander Heights, Marangaroo and Girrawheen.
From small garden retaining walls to long structural boundary walls, the crew that quotes your job is the crew that builds it. See all areas we serve
Often, yes. Many Perth councils require a building permit once a retaining wall exceeds 500 mm in height, and some also want engineering drawings. The threshold and the paperwork vary between local governments, so the answer depends on which council you are in and where the wall sits on your block. We check with your council as part of quoting the job.
It depends on what the wall is doing. Limestone block suits garden terracing and front-yard levelling and matches the look of most Perth suburbs. Concrete sleepers with galvanised steel posts suit boundaries, higher walls and anywhere a fence is going on top. Panel-and-post is cost-effective over long straight runs. We will tell you which one your job actually needs at the measure.
It depends on the length, the height and how much excavation is involved. A short garden wall can be a one-day job. A long boundary wall with a fence on top runs longer. We give you a start date and a realistic timeframe with your quote rather than after you have committed.
Yes, and it is usually the better way to do it. The wall height changes where the fence sits, so building them as one job avoids gaps at the base and avoids two trades blaming each other. We do both.
Yes. Demolition, excavation, spoil removal and site clean-up are included in the quoted price. You will not get a separate bill for the rubbish.
Almost always drainage or footings. Perth sand lets water run straight through and it collects behind the wall, and the pressure pushes the wall out. Footings that do not reach solid ground let the whole thing settle. Both are invisible once the job is finished, which is why they get cut.

Yes. Our retaining wall builders construct high retaining walls for residential and commercial projects. We assess the structural requirements carefully so every wall is safe, compliant and built for long-term durability, and we arrange engineering where the height or the council requires it.
Yes. WA Fencing and Retaining provides retaining wall construction and installation throughout Perth for residential, commercial and landscaping projects.
Project timelines vary depending on the size, height, site access, and wall type. During your consultation, we provide a clear timeframe and keep communication consistent throughout the installation service.
Yes, depending on the retaining wall design and structural requirements, we use steel reinforcing to improve strength, durability, and long-term stability. Reinforced retaining wall systems are especially important for structural retaining walls and high retaining applications where additional support is required.
Galvanised steel is commonly used in retaining wall construction because it provides excellent corrosion resistance and long-term durability in harsh WA conditions. Galvanised steel posts and supports help reinforce retaining wall systems while reducing maintenance over time.
Retaining wall blocks are designed to provide structural support while creating clean and functional outdoor spaces. They are commonly used for garden edging, soil retention, landscaping projects, and creating level outdoor areas for residential and commercial properties.
Yes, high-quality limestone retaining walls are a durable and popular solution across Perth. Limestone offers natural strength, long-lasting performance, and a clean finish that suits a wide range of landscaping and retaining wall needs.
Yes, retaining walls and retaining wall blocks can be incorporated into garden edging to help define landscaping areas, manage soil movement, and improve the overall appearance of outdoor spaces.
