Concrete Western Sydney

Highly reactive clay from Bringelly shale

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. In a wet season the clay swells and in a dry summer it shrinks and cracks, which is why so many older driveways out west have heaved or split. Concrete here needs a properly compacted base, the right mesh and closely spaced control joints. Summer heat matters too: on 35°C-plus days concrete sets fast, so pours are scheduled for early morning.

What to plan for in Western Sydney

Low-lying and flood-affected land

Parts of the suburb are low-lying. Garage and driveway levels may need to sit at or above a flood level set by council, and every slab needs falls that carry water away from the house.

Strata approval

Work on common property needs owners corporation approval, and building managers often ask for the contractor's insurance certificates and a work method statement. Start that early: it's usually the longest lead time on a strata job.

Councils in this area: Blacktown City Council, Canterbury-Bankstown Council, City of Parramatta, Cumberland City Council, Fairfield City Council, Liverpool City Council, Penrith City Council. Each approves driveway crossings on its own footpaths and sets the levels they must match.

Council driveway and setback rules in Western Sydney

Each council sets its own rules for crossings, driveway widths, finishes, garages and front setbacks. Summarised from their own documents, with every rule linked to its source.

Cumberland City Council

Cumberland DCP 2021

Canterbury-Bankstown Council

Canterbury-Bankstown DCP 2023 and Development Engineering Standards Guide (Aug 2024)

  • Crossing & approvals

    A new vehicular footway crossing needs a council work permit, which sets its geometry and construction, and its location must comply with AS 2890.1.

    CB Engineering Standards Guide, 4.9
  • Crossing & approvals

    New crossings must be 2m clear of any street tree trunk, and any approved tree removal must be paid for and replaced by the owner.

    CB Engineering Standards Guide, 4.12
  • Crossing & approvals

    Crossings are sized and placed to keep as much on-street parking as possible. If one clashes with a council stormwater pit, the owner pays to rebuild the pit clear of the crossing.

    CB Engineering Standards Guide, 4.10
  • Excavation

    Cut or fill deeper than 500mm must be done under the supervision of a NATA-registered geotechnical consultant, with compaction testing certified and submitted to council.

    CB Engineering Standards Guide, 4.5

Blacktown City Council

Blacktown DCP 2015, Part C Development in the Residential Areas

  • Crossing & approvals

    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.

    Blacktown DCP 2015 Part C, 3.5.3
  • Driveway

    Each parking space must be at least 5.5m long by 3m wide (2.75m each in a side-by-side double), and driveway grades must comply with AS 2890.1.

    Blacktown DCP 2015 Part C, 3.5.3
  • Garages & parking

    Garage doors or carports can take up no more than 50% of the front of the house, and two parking spaces must be provided behind the building line, not in the front setback.

    Blacktown DCP 2015 Part C, 3.2.3 and 3.5.3
  • Front setback

    The minimum front building line for a house is 6m (4.5m in the Stanhope Gardens estate, except homes facing Stanhope Parkway with rear driveways).

    Blacktown DCP 2015 Part C, 3.2.3

Fairfield City Council

Fairfield Driveway (Vehicular Crossing) Policy 0-088

  • Crossing & approvals

    One vehicle crossing per lot (granny flats don't get a second). Crossings are a maximum of 3m wide for a single garage or no garage and 4.5m for a double garage, and each lot in a duplex or triplex gets a maximum 3m crossing.

    Fairfield Policy 0-088, requirements
  • Crossing & approvals

    Crossings must be at least 6m from the tangent point at an intersection, 0.3m from the neighbour's driveway and wholly within your frontage. Old laybacks must be removed and replaced with standard kerb.

    Fairfield Policy 0-088, clauses 6–7
  • Crossing & approvals

    Where there's no footpath, the nature strip either side of a cut-in driveway must be battered no steeper than 1 in 14, and the footpath slope can't exceed 5% along its length. Moving pits, hydrants or stormwater outlets is at the owner's cost.

    Fairfield Policy 0-088, requirements
  • Concrete finish

    Council specifies plain concrete for crossings, in a wood float, trowel or broom finish, so repairs match. Pavers aren't authorised on crossings, and council won't colour- or pattern-match a decorative crossing if it has to dig it up.

    Fairfield Policy 0-088, clauses 10–12

Penrith City Council

Penrith DCP 2014, D2 Residential Development

  • Driveway

    Driveways should be kept small so the front garden keeps enough landscaping.

    Penrith DCP 2014 D2, 2.1.5 (3)(a)
  • Garages & parking

    Garages, carports and parking spaces aren't permitted in the front setback, apart from stacked parking on the driveway leading to a garage. Only verandahs and pergolas may encroach, by up to 1.5m.

    Penrith DCP 2014 D2, 2.1.2(c)
  • Front setback

    The front setback for a single dwelling is the greater of 5.5m or the average setback of the adjoining houses. On a corner block the secondary frontage is 3m to walls and 5.5m to garage entrances.

    Penrith DCP 2014 D2, 2.1.2(a)–(b)

Suburbs we cover in Western Sydney

Auburn 2144

Cumberland City Council

Auburn is post-war homes, many being replaced by duplexes and new builds, on flat clay ground near Duck River. New-build driveways and replacements of old cracked concrete are both common here.

Bankstown 2200

Canterbury-Bankstown Council

Bankstown has apartments around the centre and post-war brick and fibro homes on flat clay blocks further out. Older driveways here often crack and lift as the clay moves, which is the most common reason for replacement.

Blacktown 2148

Blacktown City Council

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.

Doonside 2767

Blacktown City Council

Doonside is largely 1960s and 70s brick and fibro homes on flat, reactive clay near Eastern Creek. Wide blocks with side access make pours straightforward, but low-lying streets need drainage planned in.

Fairfield 2165

Fairfield City Council

Fairfield is post-war homes on clay, with low-lying land along Prospect Creek that is flood-affected. Garage and driveway levels need to sit above flood levels where council has set them.

Guildford 2161

Cumberland City Council

Guildford's older brick and fibro homes are steadily being replaced by duplexes and granny flats. That means a lot of new driveways, shared accessways and paths poured on clay that needs good base preparation.

Liverpool 2170

Liverpool City Council

Liverpool has apartments in the centre and established homes and newer estates around it, on clay soils near the Georges River. River-side streets are flood-affected, and summer heat means early-morning pours.

Merrylands 2160

Cumberland City Council

Merrylands has apartments near the station and post-war homes that are being redeveloped into duplexes. New driveways, shared accessways and paths on clay are the common jobs.

Mount Druitt 2770

Blacktown City Council

Mount Druitt was largely built as 1970s estates on reactive clay, and many original driveways have now cracked or heaved. Replacement work here usually means breaking out the old concrete and rebuilding the base properly.

Parramatta 2150

City of Parramatta

Parramatta has a high-rise CBD, heritage areas such as Harris Park nearby, and flood-affected land along the river. Jobs range from strata courtyards to driveway replacements on older homes.

Penrith 2750

Penrith City Council

Penrith sits on the Nepean River floodplain, with established homes near the centre and newer estates around it. It is one of the hottest parts of Sydney in summer, so pours start early and the slab is cured carefully to stop it drying too fast.

Seven Hills 2147

Blacktown City Council

Seven Hills is mostly post-war brick homes on clay, with gentle slopes and good side access on most blocks. Old driveways here commonly crack as the clay moves, so replacements include rebuilding the base.

Wentworthville 2145

Cumberland City Council

Wentworthville is post-war homes on clay, with low-lying parts along Toongabbie Creek. Duplex redevelopment is bringing new driveways and shared accessways alongside replacement work.

Westmead 2145

City of Parramatta (parts in Cumberland)

Westmead is the hospital precinct surrounded by apartments and older homes on clay. Work is a mix of strata areas and driveways on established houses.
