Canada Bay is a peninsula LGA, and the water shapes almost everything about the slab work. Blocks fall toward the Parramatta River, foreshore land has been reclaimed and filled, and the highest-value sites are frequently the most difficult ones to build on.
It is also the LGA where we most often end up pouring something other than a slab on ground. Steep harbourside blocks want stepped slabs, drop-edge beams or a suspended floor spanning off piers, and the engineering reflects that well before we quote it.
Shale ridges through the middle of the LGA, reclaimed industrial land along the foreshore, and sandstone on the harbourside slopes — the three could hardly be more different.
The spine of the LGA sits on Ashfield shale weathering to a reactive clay. Moderate to high reactivity is normal, and the slab design follows the movement rather than the load.
Substantial parts of the foreshore were industrial land before they were residential, and much of it was reclaimed and filled. Deep fill, contamination management and piering to competent ground are all part of building here, and the geotechnical investigation is not optional.
The harbourside streets sit on Hawkesbury sandstone and fall hard toward the water. Ground is far less reactive, but shallow rock and cross-fall push the job toward stepped slabs, drop-edge beams or a suspended floor.
These are the conditions we typically strike across Canada Bay — 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.
Replacing older stock across Five Dock, Concord and Russell Lea. Standard slab on ground work where the block is flat, and something more involved once it starts to fall.
Drummoyne, Chiswick and Abbotsford blocks that drop toward the river. Stepped slabs, drop-edge beams and suspended floors off piers, poured to the structural drawings.
Dual occupancy where the block width allows, and secondary dwellings behind existing homes. Access down narrow inner-west streets decides the method.
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.
