Kalkallo's new estates, including Cloverton, are full of fresh handovers that need driveways, side paths and boundary walls before the first winter.
Once the house is finished, most Kalkallo owners want a shed, an alfresco slab or a garage extension. The north's reactive clay means we never skip the compacted base, the vapour barrier or the steel.
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.
We bring samples to every Kalkallo measure so you can see them against your house.
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.

Kalkallo is in Hume City Council. Structural slabs in Kalkallo — houses, extensions and granny flats — need an engineer's design and a building permit through your building surveyor. If trucks will cross the nature strip, check whether Hume City Council needs an asset protection permit.
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.
