A slab is only as good as the ground and the steel. Much of Melbourne's north sits on reactive clay that swells when wet and shrinks when dry, so a slab that's too thin or poorly reinforced will crack and move.
For shed and outdoor slabs we excavate, compact a crushed-rock base, lay vapour barrier and steel, and pour to level with thickened edges where needed. For house slabs, extensions and granny flats we build exactly to the engineer's design — beams, steel, set-downs and plumbing penetrations — and book the steel inspection before the pour.
Not sure which one? We'll talk you through it at the measure and bring samples.
Level, reinforced slabs with thickened edges and bolt-down positions — $75–$115 per m².
Built to take vehicles, with falls to the door so water runs out, not in.
Engineered waffle or raft slabs built to your engineer's plans — $110–$170 per m².
Engineered slabs with plumbing set-downs, coordinated with your builder and plumber.
Level outdoor slabs ready for tiles, decking frames or a broom finish.
Tight backyard? We bring in a concrete pump so nothing gets barrowed through the house.

Indicative 2026 Melbourne ranges for standard access. Your price depends on size, access, excavation, slope and finish — you get a fixed written quote after a free on-site measure.
Free on-site visit. We check levels, access, soil and drainage, then give you a fixed written price.
Excavation, compacted crushed-rock base, formwork, steel reo and vapour barrier — the bit you never see.
Australian premix pumped or barrowed in, screeded to falls, then finished — broom, trowel, coloured or exposed.
Control joints saw-cut, surface sealed, site cleaned up. You get care instructions and a slab that lasts.
House slabs, extensions and granny flats need an engineer's design and a building permit. Small shed and outdoor slabs usually don't, but we still build them to a proper spec with steel and a compacted base.
Most shed slabs are 100 mm thick with steel mesh and thickened edges under the walls. Bigger sheds, or ones that will hold cars or machinery, may need more — and some shed kits come with an engineered slab spec we follow.
Yes. We use a line pump to pump concrete over or around the house, so there's no barrowing through your hallway.
You can usually start framing or erect a shed after about 7 days. Concrete keeps gaining strength for 28 days.
