Ryde is a rebuild market more than a greenfield one. Most of the slabs we pour here go down on a block that already had a house on it — a post-war brick home cleared for a new build, a duplex replacing a single dwelling, or a granny flat squeezed into a back yard behind an existing house.
That changes the job. Demolition spoil has to be gone and the pad has to be right before we set out. Access is usually tight, neighbours are close on both sides, and the pour is often planned around a pump rather than a chute. We price all of that into a fixed quote up front instead of finding it on the day.
Ryde straddles two very different geologies, and the split runs roughly along the ridge lines. Which side of it your block sits on drives the slab system, the depth of the beams and a meaningful share of the price.
The higher ground through the north of the LGA is typically Wianamatta shale weathering to a reactive clay. Reactive ground moves with moisture, so it usually classifies moderately to highly reactive and wants stiffer edge beams, a deeper waffle or a raft.
Closer to the Parramatta and Lane Cove rivers the shale thins out over Hawkesbury sandstone. Ground is far less reactive, but blocks fall away toward the water and rock can turn up shallow — so the cost moves from reinforcement into excavation, rock removal and stepped or drop-edge slabs.
Older Ryde blocks were often cut and filled to make a flat building platform, and uncontrolled fill cannot be counted on to hold a slab. Where fill is deep the engineer will usually pier through it to natural ground or call the site Class P.
These are the conditions we typically strike across Ryde — 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.
The bread and butter of Ryde slab work. Once demolition is done we take over the pad — level checks, excavation, service set-out, reinforcement and pour — and hand a certified slab back to your builder.
Dual-occupancy sites through West Ryde, Eastwood and Denistone usually mean a wider slab, a party-wall footing and tighter boundary setbacks. We set out both dwellings off one survey so the walls land where the plans say.
A backyard secondary dwelling behind an occupied house is an access job first and a concrete job second. We plan the pump line, protect the driveway and existing services, and get in and out in a day where the site allows.
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.
