House Slabs in Parramatta
Waffle pod and raft slabs for new homes, duplexes and granny flats across the City of Parramatta — Westmead and Northmead through to Epping, Carlingford and the river suburbs.
Waffle pod and raft slabs for new homes, duplexes and granny flats across the City of Parramatta — Westmead and Northmead through to Epping, Carlingford and the river suburbs.
Parramatta is the closest big market to our Merrylands yard — most sites are ten or fifteen minutes away, which means we can get to a pre-pour inspection or a levels check the same day rather than the next one.
The slab work here splits three ways: knock-down rebuilds on the older shale ridges, dual-occupancy and duplex sites through Northmead, Dundas and Winston Hills, and granny flats behind existing homes almost everywhere in the LGA.
Parramatta covers ridge, river flat and old industrial land inside one LGA, and the three behave nothing alike once you start digging beams.
The high ground across the north of the LGA is Wianamatta shale weathering to a reactive clay. It swells and shrinks with moisture, so it usually classifies moderately to highly reactive and the engineer will ask for stiffer edge beams or a raft.
Down on the Parramatta River and the Duck and Darling Mills creek lines the ground turns alluvial — soft silts and clays of variable depth, often with a flood planning level attached. Piering through to competent ground is common rather than exceptional.
Parts of the river corridor were industrial before they were residential, and the fill left behind is deep and uncontrolled. Expect a full geotechnical investigation and a slab designed around what it finds, not around a standard detail.
These are the conditions we typically strike across Parramatta — 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.
Post-war brick homes across Northmead, Telopea and Dundas Valley are steadily being cleared for new builds. Once demolition is off the block we take the pad from levels through to a certified slab.
Dual-occupancy approvals are thick on the ground through Winston Hills, Northmead and Constitution Hill. Wider slab, party-wall footing, two sets of services — all set out off one survey.
A secondary dwelling behind an occupied house is an access problem before it is a concrete one. We plan the pump line, protect the existing driveway and services, and keep the disruption to a day where we can.
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.
