Flat, square, reinforced and machine-trowelled
A shed slab has to do two things: be dead flat and dead square so the frame goes together without a fight, and take whatever ends up on it — a hoist, a workbench, a boat, a ute.
We pour slabs for garden sheds, garages, workshops and farm sheds, finished with a power trowel so the surface is hard, dense and easy to sweep. We pour the slab and leave it ready for your shed builder; we do not erect sheds, and we do not do house or building slabs.
Everything that goes into the price
- Excavation to depth and spoil cartage
- Compacted crushed rock base
- Formwork set square and level to the shed footprint
- Edge thickening where the shed frame bears
- Reinforcement specified to the slab, on chairs
- Concrete placed, screeded and machine-trowelled
- Rebates or cast-in fixings where the kit calls for them
- Control joints cut, curing compound applied, site cleaned
Why a good slab saves you a bad shed
Square to the kit
Bring us the shed plan or kit specification before we form up. Kit sheds are unforgiving: the slab has to match the frame, including where the anchors land.
Edge thickening
The perimeter is thickened where the frame bears, so the edge does not break away under load.
Specified to the use
A garden shed slab and a workshop slab with a hoist on it are different builds. Thickness and reinforcement are set against the use, not off a standard sheet.
Flat enough to work on
A workbench that rocks and a roller cabinet that runs to one corner both come back to the slab. Machine trowelling is what stops that.
The ones we get asked most
What thickness does a shed slab need?
It depends entirely on what is going in it and what the ground is like. Tell us the use and we will set the thickness and reinforcement to suit, and state both on the quote.
Do I need a permit for a shed slab?
The slab itself usually does not, but the shed often does, depending on size, height and where it sits on the block. Your council or shed supplier will tell you.
Can you pour the slab before the shed arrives?
That is the usual order. We need the shed dimensions and anchor details first.
Do you erect the shed as well?
No — we pour the slab and leave it flat, square and ready for your shed builder.
Can I get a polished finish inside?
Yes. A machine-trowelled slab is the right base for it, and polished concrete is a popular workshop and garage floor. Tell us before the pour so we prepare the surface accordingly.
