What affects a concrete job in Blacktown
Blacktown is mostly post-war to 1980s homes on reactive clay, with newer estates on its edges. The clay here moves a lot, so base compaction, mesh height and joint spacing matter as much as the concrete.
Western Sydney is built on clay weathered from Bringelly and Ashfield shale, and some of it is among the most reactive soil in the city. More on concreting in Western Sydney →
Local council
Blacktown City Council. The section between your boundary and the kerb is council land, so a new or rebuilt driveway crossing needs Blacktown City Council's approval and has to match the levels it issues. We'll tell you at the site visit whether your job touches it.
Reactive clay
Most Blacktown blocks are straightforward to access, so the ground is the main variable. Clay that swells and shrinks needs a compacted road-base layer, mesh held at the right height and control joints close enough to stop random cracking.

Rules that apply anywhere in NSW
A driveway, hardstand or paving on your own land is exempt from planning approval only if it isn't in a heritage conservation area, on a heritage item, in a foreshore or environmentally sensitive area, drains to an existing stormwater system, and is built to AS/NZS 2890.1. Otherwise it needs a DA or CDC.
NSW Codes SEPP, exempt development: driveways, pathways and pavingAnything built on or over the footpath or road, including the vehicle crossing and layback, needs approval from the council (or Transport for NSW on State roads) under the Roads Act 1993, even when the work on your land is exempt or already approved.
NSW Codes SEPP, exempt development: driveways, pathways and pavingDriveway grades follow AS/NZS 2890.1: generally no steeper than 25% (1 in 4) within the property, and any change in grade over 12.5% (1 in 8) needs a transition, usually about 2m long, so cars don't scrape.

Do I need council approval for a driveway in Blacktown?
A driveway on your own land is only exempt from approval if it isn't in a heritage conservation area, on a heritage item or in a foreshore or environmentally sensitive area, drains to stormwater and meets AS/NZS 2890.1. Otherwise it needs a DA or CDC. The crossing between your boundary and the kerb is council land, so Blacktown City Council must approve it under the Roads Act. The crossing must be at least 1m from any gully pit or service infrastructure in the road reserve, and on a corner block at least 6m from the tangent of the kerb return.
What ground conditions affect concrete in Blacktown?
Highly reactive clay from Bringelly shale. Blacktown is mostly post-war to 1980s homes on reactive clay, with newer estates on its edges. The clay here moves a lot, so base compaction, mesh height and joint spacing matter as much as the concrete.
