Licensed Concreters in Kellyville NSW — Driveways, Slabs & Decorative Concrete

A plain or broom-finish concrete driveway in Kellyville costs $80–$150/m² supplied and laid in 2026, so a typical 40m² single driveway runs roughly $3,200–$6,000. Exposed aggregate is $120–$200/m² and stencil or stamped is $130–$220/m². Because Kellyville sits on Ashfield Shale (the named Kellyville Laminite Member, typically Class M to H1/H2 under AS2870*), expect a 10–20% reinforcement premium. A driveway slab is Exempt Development, but the vehicle crossing onto the The Hills Shire footpath needs a separate s138 application and council consent before works start ($300–$1,500 permit*). Get three written quotes and verify the licence at verify.licence.nsw.gov.au.

The driveway slab itself is usually Exempt Development under the NSW SEPP (Exempt and Complying Development Codes) 2008 — no DA needed for a standard ground-level concrete surface within your property. The catch is the vehicle crossing: the layback that crosses The Hills Shire footpath and kerb needs a separate s138 Roads Act application, and council requires the crossing to be constructed before the Occupation Certificate is issued. Decorative work near the Merriville House state heritage item on Vinegar Hill Road, or a new slab on a Cattai Creek or Second Ponds Creek flood-affected street, can trigger extra controls. Confirm your lot's flood and heritage status with council before pouring.

The main cause is reactive clay. Kellyville sits on the Ashfield Shale of the Wianamatta Group — the local sub-unit is literally named the Kellyville Laminite Member — and it weathers to clay with appreciable shrink-swell movement. It swells when wet and shrinks when dry, lifting and cracking slabs and paths. Most Kellyville sites classify as Class M to H1/H2 under AS2870*. A driveway built without enough steel, proper edge thickening and saw-cut control joints will crack within a few seasons. Mature street trees through 'The Village' add root heave on top. The fix is correct reinforcement to AS3600/AS2870, control joints at the right spacing and good drainage.

Volume equals area × thickness. A 40m² driveway at the standard 125mm needs about 5 cubic metres of concrete, plus a 10% wastage allowance — so order around 5.5m³. At 150mm for a heavier driveway or shed slab, the same 40m² needs about 6m³ plus wastage. Anything over roughly 1.5m³ should be ready-mix delivered by truck. Use the free volume calculator above to get the cubic metres, the bag-versus-truck call and a rough delivered cost, then confirm the strength (commonly N20–N25 for driveways, 32 MPa for structural slabs) with your concreter and supplier.

A residential house or shed slab in Kellyville costs $85–$160/m² supplied and laid in 2026. The figure moves with soil class: because Kellyville's reactive Wianamatta clay (the named Kellyville Laminite Member) is typically Class M to H1/H2 under AS2870*, slabs here need engineered reinforcement, deeper edge beams and sometimes a stiffened raft or waffle pod, which pushes cost toward the top. The slab is designed to AS2870 (residential slabs and footings) and AS3600 (concrete structures). Get a site soil classification before final pricing — a Class H2 site costs meaningfully more than a Class M one.

Exposed aggregate costs $120–$200/m² versus $80–$150/m² for plain or broom finish — roughly 40–50% more. It buys a slip-resistant textured surface that suits driveways, pool surrounds and paths, plus a decorative finish that lifts kerb appeal — popular across Kellyville's newer estate streets and renovated Hills homes. On reactive Kellyville clay the finish makes no difference to cracking — the reinforcement, control joints and edge beams do. Spend on the steel first, then choose the finish on looks and slip resistance.

Yes, for any concreting work over $5,000 in combined labour and materials. Structural and landscape concreting is licensed trade work under the Home Building Act 1989. For residential building work over $20,000, the contractor must also hold Home Building Compensation Fund (HBCF) insurance through icare NSW before taking a deposit. An unlicensed concreter cannot hold HBCF, and using one can void your home insurance and leave you with no recourse if the slab fails. Verify any concreter's licence in 30 seconds at verify.licence.nsw.gov.au before money changes hands.

A vehicle crossing in Kellyville needs a Roads Act 1993 s138 approval from The Hills Shire Council before any work, lodged via Council ePathway. Council allows a private certifier to issue a CDC before the crossing application is lodged, but the crossing must be constructed before the Occupation Certificate is issued. Budget roughly $300–$1,500* for the application and inspection fees and $500–$2,000* for an asset-protection bond — figures benchmarked against comparable NSW LGAs because The Hills did not publish a single clean current crossing fee in the schedules checked. Call the Subdivision Duty Officer on 02 9843 0374 to confirm live figures. The crossing is separate from the driveway slab — the slab is Exempt Development, the crossing is not.

Parts of Kellyville are. The suburb is bounded by Cattai Creek to the north and east, and by Second Ponds Creek, Caddies Creek and Smalls Creek to the west, and The Hills Shire publishes flood mapping precinct by precinct. The 1% AEP flood is the NSW Floodplain Development Manual planning standard. On a flood-affected lot, slab levels, fall and drainage have to be designed so water runs away from the house and the slab is set to the right level — set a minimum fall of around 1:100 on driveways and paths. Check your property's flood status on the The Hills Shire interactive map before designing any slab or driveway near the creek lines.
