House Slabs Brisbane

Brisbane slab work is defined by its ground. The clays across much of the city’s south are moderately to highly reactive, which is why Brisbane slab designs lean on stiffened rafts and waffle systems and why the site classification report is the most important document on the job. High Calibre Concrete Construction pours house slabs across Brisbane’s southside for new homes, and increasingly for extensions, granny flats and secondary dwellings as established blocks are developed further. Infill work is its own discipline: tight access down the side of an existing home, pump pours over houses, protecting neighbouring structures and matching levels to an existing floor. We build each slab to the engineer’s design and AS 2870, coordinate penetrations with your trades, and document reinforcement before concrete goes anywhere near it.

Reactive clay across southern Brisbane commonly produces M, H1 and H2 site classifications, which drive stiffer, deeper slab designs. Granny flat and extension slabs on established blocks usually require pump placement and careful protection of existing structures. Brisbane City Council and private certifiers set the inspection hold points we build around.
