Waffle pod and raft slabs for new estate builds, rebuilds and granny flats across the City of Blacktown — Marsden Park and Schofields through to Mount Druitt and Seven Hills.
Blacktown is the biggest new-home market we pour into. The north of the LGA — Marsden Park, Schofields, Riverstone, The Ponds — is release land turning into streets, and the slabs there go down on blocks that were paddock two years ago.
That is a different job to a rebuild. The pad is already shaped by the developer, the fill has a compaction report attached to it, and the builder is working to a programme with a handover date on it. We quote to the engineering, book the pour against your inspection, and turn up when we said we would.
Almost all of Blacktown sits on Wianamatta shale, which makes it some of the most reactive residential ground in Sydney. What varies is how much of the block the developer already moved.
Weathered Wianamatta shale produces a clay that moves a long way with moisture. Highly reactive classifications are the norm here rather than the exception, which pushes most blocks toward a deeper waffle or a raft with substantial edge beams.
Release land is cut and filled to make level building platforms. Where the fill is controlled and certified the slab can be designed on it; where it is not, the engineer will pier through it. Get the compaction report to us with the plans.
The creek corridors running through the LGA carry alluvial soils and flood planning levels. Finished floor level is set by the flood study, not by the natural surface, so the fill and the slab design follow from that.
These are the conditions we typically strike across Blacktown — 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.
Volume and custom builders working the northern release areas. Set-out to the engineering, services in before the pour, certified slab handed back on the programme date.
Older stock through Mount Druitt, Doonside, Lalor Park and Blacktown proper is steadily being replaced. We take the block from cleared pad to poured slab.
Large back yards across the established suburbs make Blacktown strong granny flat territory. Usually a pump job past the existing house, in and out inside a day.
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.
