The unseen
craftsmanship
everything sits on.

A shed slab is the most honest piece of concrete we pour. There is no decorative finish to admire, no colour to discuss — its entire value lies in being flat, level, strong and correctly prepared. And precisely because it is invisible, it is the work most often cut short by operators chasing a cheap price. A slab that is out of level, under-reinforced or poured on poorly compacted ground will cause problems for the life of the structure above it: doors that won't sit square, walls that crack, floors that move.

At Artisan Concrete we pour shed, garage and workshop slabs to engineer specification across Perth, and we treat the preparation as seriously as the pour. Whether the slab is for a modest garden shed, a large American barn, a workshop, a granny flat or a commercial outbuilding, the principles are the same — and we do not compromise on them.

Preparation decides everything

The strength of a slab is built before any concrete arrives. We begin by stripping organic topsoil and cutting the pad to level. We then lay and compact a proper road-base sub-grade in layers, because uncompacted fill is the single most common cause of slabs settling and cracking after the fact. Where ground conditions or the structure require it, we install a vapour barrier to keep ground moisture out of the slab and the building above.

Edges are thickened where the structure's loads come down, and footings are formed to suit the shed or building design and the engineer's details. This edge detailing is exactly where budget slabs are quietly skimped — and exactly where failures begin.

Reinforcement and thickness to spec

We reinforce every structural slab with steel mesh, and where required by the engineering, with additional bar through thickened edges and footings. Slab thickness is matched to the use: a slab destined to carry a vehicle hoist, heavy machinery or stored loads is engineered very differently from one supporting a light garden shed. We follow the engineer's design where one exists, and we will advise you when an engineered design is the sensible path.

Dead level, correct falls

A shed slab must be flat and level so that wall frames sit true and doors operate correctly — but it also usually needs a subtle fall to a door or drain so that any water that enters finds its way out rather than sitting on the floor. Balancing a dead-level plane for the structure with the right drainage fall is a matter of careful set-out and laser levelling. We get this right at the formwork stage, because it cannot be fixed afterwards.

Control joints and curing

As with any concrete, a slab shrinks as it cures and will relieve that stress somewhere. We saw-cut control joints at the correct spacing so the slab cracks at planned lines rather than randomly across the floor. We then cure the slab properly — critical in Perth's heat — to control moisture loss and build full strength, so the finished floor is hard-wearing and dust-free.

One team, properly coordinated

Because we also carry out excavation and earthworks in-house, we can handle a shed slab project end to end — site cut, fill, compaction, formwork, reinforcement, pour and finish — without juggling multiple contractors. That means the preparation and the pour are coordinated by one team who are accountable for the whole result, and it usually means a faster, cleaner job for you.

If you are ordering a shed or kit building, your supplier will often specify the slab dimensions and tolerances required. Bring us those details — or your engineer's plans — and we will prepare and pour a slab that meets them exactly. Book a consultation and we will assess the site, confirm levels and access, and provide a clear fixed-price quote.

Why Perth homeowners choose Artisan

There is no shortage of people in Perth who will pour concrete. There are far fewer who treat concrete shed slabs as a craft — who care as much about the parts you will never see as the finish you will. After more than twenty years and over five hundred completed projects, our reputation rests on a simple idea: do the unglamorous work properly and the beautiful work looks after itself.

That means honest advice at the consultation, even when it costs us a sale. It means a single, accountable team from the first measure to the final seal, rather than a chain of subcontractors pointing fingers. It means transparent, itemised fixed-price quotes with no surprises on invoice day, and a clean, respectful site that we leave better than we found it. And it means standing behind the result long after the trucks have gone.

Workmanship that holds up

Concrete is unforgiving — the decisions made in the first hours of a pour are locked in for decades. Correct reinforcement, properly spaced control joints, falls set to the millimetre, curing managed against the Perth heat and a sealer matched to the finish are not upsells; they are the difference between a surface that still looks intentional at fifteen years and one that looks tired at five. We do them as standard because cutting them is how cheap work earns its price.

Servicing Perth & the hills

We work right across the Perth metropolitan area and into the hills — including Stoneville, Parkerville, Darlington, Mundaring, Mahogany Creek, Stoneville and the surrounding suburbs. Whether your block is free-draining coastal sand in the north or clay and rock in the hills, two decades across these conditions means we read a site quickly and prepare for what is actually under your feet. If you are nearby and not listed, ask — we very likely cover you.

What to expect next

Getting started is simple. Request a consultation and we will arrange a time to walk your property, understand what you are picturing, and assess access, levels, falls and drainage. We will talk through finishes honestly, bring samples where it helps, and then return a clear, transparent fixed-price quote — usually within one business day. There is no obligation and no pressure: just the information you need to make a confident decision about a surface you will live with for a very long time.
