01The local market
Western Australian builder-registration rules are not a simple trade threshold that every concrete ad can summarise in one badge. Current Building and Energy guidance says builder work generally involves work that needs a building permit, is carried out in a prescribed area and is valued at $50,000 or more for a Class 10a building or $20,000 or more for other building work. A Class 10a building can include a private garage, carport or shed, and local government or a building surveyor should confirm the building classification and permit requirements.
The guidance also describes exemptions, including work where a permit is not required and some work carried out under a registered building contractor. A Perth concreter should therefore check the contracting role, whole scope, value, classification, permit and supervising builder before describing itself as registered, exempt or authorised. A slab associated with a garage, shed, home, pool or retaining project may sit inside a larger building job; one concrete component should not be separated from that context merely to support a marketing claim.
Contract protections use a different band. The WA Government says the Home Building Contracts Act applies to fixed-cost home-building work contracts between $7,500 and $500,000, including associated work such as garages, sheds and landscaping, whether or not the builder is registered. Its current homeowner guidance says the builder must provide the prescribed notice before signing, the contract must be written and signed, and the maximum deposit in that range is generally 6.5 per cent.
It separately says home indemnity insurance is required for building work needing a building permit and valued above $20,000, subject to the actual work and applicable exceptions. An ad can ask about the complete project and broad budget, but it should not promise that every driveway or slab is automatically insured, registration-free or covered by the same contract rule. The business must confirm the Act, registration, permit, insurance, deposit and variation requirements for the actual arrangement before money or work changes hands.
Driveways create another boundary. The City of Perth says a crossover between the road edge and property needs approval before work starts and asks for a sketch showing dimensions, the property boundary, trees, poles and pits that may be affected. Its streets and verges guidance also says permission is needed to move or redevelop a driveway.
02The campaign setup
That process does not govern the whole metropolitan area. Joondalup, Midland, Armadale and Rockingham sit under different local governments or service contexts, with their own crossover materials, footpath continuity, kerb, drainage, verge and inspection requirements. A Perth campaign should collect the local government, road type, existing driveway and crossover, verge, footpath, kerb, trees, services, pits and proposed change.
It should not call a driveway council-approved merely because the private slab appears straightforward. Limited truck or pump access, shared driveways, coastal exposure, sloping blocks, limestone, demolition, neighbouring property and occupied areas can also change what needs a site review; those conditions should be confirmed rather than guessed from a postcode. Cutting and removal claims require equal care.
WorkSafe WA says quick-cut saw use on masonry and concrete generates respirable crystalline silica even when wet methods are used, and its guidance covers dust, fumes, support of the material, cleanup and the hierarchy of controls. It warns that petrol-powered saws can create hazardous carbon monoxide in enclosed or partly enclosed spaces and says silica slurry or dust should not be left to become a later exposure. An ad should not describe cutting as dust-free, harmless or controlled by water alone.
A lead form can identify whether existing concrete needs cutting, grinding, drilling or removal, whether the space is enclosed and who may be nearby, while the responsible business completes the risk assessment and selects the equipment, ventilation, extraction, respiratory protection, exclusion and cleanup controls.
03Claims and hand-off
Stormwater and washout questions are useful before an agitator or pump arrives. The WA Stormwater Management Manual recommends contingency measures to prevent concrete-pump spills entering drainage, keeping wastewater from cutting or grinding out of stormwater, allowing concrete slurry to set before suitable disposal and removing waste rather than flushing loose material.
These are statewide best-practice controls, not a promise that one disposal method suits every site or local authority. The enquiry can flag visible drains, slope, pump location, washout plan, access, spoil and cleanup, then the supplier and contractor confirm the compliant site method. Price and finish claims still need a defined scope.
Exposed aggregate, honed, coloured, stamped, stencilled, polished and resurfaced concrete can vary with the substrate, preparation, reinforcement, thickness, joints, mix, placement, weather, curing, sealer, loads and maintenance. A headline rate may exclude excavation, spoil, pumping, reinforcement, drainage, approvals, traffic management, restricted access or GST.
The ACCC says claims about services, prices, benefits and future matters must be accurate and supportable. Perth creative should state meaningful inclusions and conditions, show genuine project examples, explain sample and photography limits, and avoid unconditional no-crack, exact-colour, salt-proof, same-day, lifetime or maintenance-free promises.
