A slab under a building is structure. It carries the shed, the garage, the granny flat or the extension for the life of the building, and it has to be right before anything goes up, because nothing about a slab can be fixed cheaply afterwards.
Poured to the drawings
Where a slab carries a building, the design comes first: an engineer’s drawings for the larger and habitable work, standard details for simple garden sheds. Thickness, mesh or bar, edge beams and membrane are set by the design and the soil classification, and the pour follows the drawings, with inspections coordinated where the building approval requires them. The numbers we pour to are published on the specification page.
Ground from sand to clay
The coast’s blocks are not one soil. Beach side suburbs sit on sand that needs compaction and moisture control; the hinterland runs to reactive clay that moves between wet and dry seasons and asks more of edge beams and reinforcement. The slab that suits a Golden Beach block is not the slab that suits Maleny, and the design reflects that.
Levels, access and the pour
Slab day is about logistics: pump or chute access, levels off the datum, and enough hands to place, screed and finish before the Queensland heat closes the window. Jobs are planned for morning pours in the warm months, and the slab is cured, not just left, because early strength decides the floor’s flatness and durability.
What it costs
Slab rates depend on thickness, steel and edge beams as much as area, so the range is wider than surface work. The rates guide sets out what moves the number. Prices may vary with site conditions and variations; the written quote after a site measure is fixed.
