Concrete — Blackwood 5051
Concrete Work in Blackwood, SA 5051
Blackwood is about 10.4 km from the Adelaide CBD, well inside our 60 km service area. On this ground the base, the joints and the fall matter more than the surface finish, and this page covers how a concrete job is handled for a Blackwood property, from the first site visit to the pour.
What Blackwood is built on
The ground under a Blackwood slab
Blackwood sits on the first serious rise of the Mitcham foothills, and rock is close to the surface almost everywhere. Soil is shallow over fractured rock, so a slab pad or driveway base often means breaking out stone before the level is reached. Big treed blocks and sloped sites are the norm, which shapes both the base and how the concrete reaches the forms.
How it goes
From site visit to pour in Blackwood
The pour itself follows the same disciplined sequence everywhere, but the Blackwood version of it starts with the ground: foothills ridge-and-gully country, with most blocks sloping in at least one direction. Access is reasonable street access on sloped sites, with two-stage material handling common on downhill blocks, so the way concrete reaches the forms is settled before anything is ordered.
01
Preparation: excavation to depth, base rubble compacted and a membrane down where specified.
02
Formwork: forms set and levelled, with heights, falls and edges fixed before any concrete arrives.
03
Steel: reinforcing mesh sits on bar chairs at the correct cover, not in the bottom of the slab.
04
The pour: truck and pump place the mix, screeded to the forms while it is workable.
05
Finish: power trowel for a burnished slab, wash-off for exposed aggregate, chosen not accidental.
06
Joints: control joints saw-cut within hours, telling the slab where it is allowed to crack.
07
Cured: sealed and cured over days, not hours, so the slab lasts.

What we look at on a Blackwood job
On a Blackwood slope the question is whether to cut into the fall or build level ground up to it, and that decides how much rock and fill the slab needs. We check the slope, the likely depth to rock and the two-stage handling a downhill block needs before pricing the base.
01
Ground: shallow soil over fractured rock, where augers meet stone early and often on a foothills ridge-and-gully country, with most blocks sloping in at least one direction block.
02
Use: a shed slab, a driveway and a path each take different steel, thickness and finish.
03
Water: where the surface falls and where run-off leaves the block.
04
Access: reasonable street access on sloped sites, with two-stage material handling common on downhill blocks, which decides whether the pour comes by chute, pump or barrow.
