Concrete Work in Sunbury

Broom (non-slip, standard outdoors), steel trowel (smooth, indoor), exposed aggregate, stamped/patterned, coloured and polished. Decorative finishes can add 30-100% to the base rate but replace the cost of a separate surface like pavers or tiles.

Surface spalling, small cracks and pitting can be patched, resurfaced with an overlay, or ground back. Slabs that have sunk can sometimes be lifted with foam or grout injection ('slabjacking') for far less than replacement. Structural failure or widespread base movement means replacement.

You can usually walk on it after 24-48 hours, drive on it after about 7 days, and it reaches design strength at 28 days. Curing (keeping it damp, protecting from frost or extreme heat) in the first week matters more for durability than almost anything else.

Concrete is priced by area and thickness for slabs (per m² or sq ft), by volume for supply (per cubic metre/yard), and by the job for repairs. The concrete itself is often less than half the bill — formwork, reinforcement, sub-base preparation, finishing and access drive the labour cost.

Look for crews who do concrete daily, not general handymen — finishing is a perishable skill and a two-hour window decides how the slab looks forever. In Sunbury, ask for addresses of slabs poured a few years ago and look at the joints and edges, which is where poor work shows first.

Plain concrete typically runs $65-95 per m² laid, coloured $75-110, and exposed aggregate $100-160. Site access, pumping and excavation add to the base rates.
