The Hills runs two very different building markets at once. In the south and west it is release land — Box Hill, North Kellyville, Rouse Hill — where estate blocks come pre-shaped and the builder is on a programme. In the north-east it is acreage, where a single home might sit two hundred metres off the road.
Both are straightforward once you plan for them. What catches people out is treating an acreage pour like a suburban one: the concrete has to get to the slab, and on a long driveway that means a pump, an agitator run schedule and a conversation before quote day, not on the morning.
The Shire straddles the shale-sandstone boundary. South and west is reactive clay; north-east is sandstone country where the cost moves out of reinforcement and into excavation.
Wianamatta shale weathering to a reactive clay across the growth corridor. Moderately to highly reactive classifications are normal, and the engineer designs the beams around the movement rather than the load.
The north-east sits on Hawkesbury sandstone. Far less reactive ground, but rock can be shallow and unforgiving — the money moves from reinforcement into rock excavation, and access down a long private driveway becomes part of the price.
Release land is cut and filled to level platforms before a builder ever sees it. Certified controlled fill can carry a slab; uncertified fill usually means piering through to natural ground.
These are the conditions we typically strike across The Hills — they are not a site classification. Your geotechnical report and structural engineer set the class and the slab design under AS 2870, and we quote and pour to whatever they specify.
Box Hill, North Kellyville and Rouse Hill release blocks for volume and custom builders. Set out to the engineering, poured against your inspection dates.
Dural, Kenthurst and Annangrove properties where the build sits well off the road. We plan the pump, the agitator turnaround and the site access before we price it.
Big blocks across Castle Hill, Baulkham Hills and West Pennant Hills make secondary dwellings common. Usually a pump past the existing house.
Send us the engineering plans and we will confirm the system and quote it within 24 hours.
Polystyrene void formers in a grid, poured as one raft on top of the ground. Least excavation, least concrete, quickest to programme. The default on stable Class S and M sites.
Learn more →Solid concrete throughout with deeper stiffening beams dug into the ground. The system for reactive clay, fill and sloping sites where a waffle will not satisfy the engineer.
Learn more →A structural slab spanning between piers, walls or a lower level. Used on steep sites, over garages and basements, and for the upper floors of two-storey builds.

Not listed? We cover the whole LGA — ask us about your suburb.
Email through the engineering drawings and the site classification, or just tell us the address and what you are building. We will come out and look at access, levels and the existing structures.
One price covering excavation, reinforcement, formwork, the pour and the paperwork. Pump access, rock and fill are priced in up front rather than raised as variations later.
We lock in a pour date around your inspections, set out to the engineer's drawings, pour and cure, and hand back a certified slab with the pour records for your building file.
