How to Avoid Concreter Scams & Dodgy Operators (2026)

The most common version is the unsolicited knock. Someone shows up claiming they have leftover concrete mix from a job nearby and can do your driveway at a heavy discount today. The pressure is immediate. The price sounds too good. Once they leave, so does your money.

Another pattern is the low-ball quote followed by inflated variations. The initial written quote looks reasonable, then once work starts you get hit with unexpected charges for extras that any experienced concreter would have priced in from the start. Subgrade prep, formwork, mesh, access fees , these are not surprises for professionals. They are standard line items.

There is also the ghost contractor: collects a deposit, does minimal or no work, then becomes unreachable. This happens more often after storms and floods when demand spikes and homeowners are desperate to get work done fast.

• Unsolicited quotes at the door, especially with urgency
• Cash-only payment with no receipt or contract
• No business address, just a mobile number
• Quotes given without inspecting the site
• Requests for a large deposit before any work begins
• No mention of a contractor licence number

Every state and territory in Australia has its own licensing system for building and construction trades. Concrete work that forms part of a structure, including driveways, slabs, retaining walls and footings, generally requires a licensed contractor. The threshold varies, but do not assume small jobs are exempt.

Always search the licence yourself using the regulator's portal. Do not rely on a number printed on a quote. Take thirty seconds to verify it is current, in the right class, and matches the person or company name on your contract.

Beyond the licence, ask for public liability insurance and, if they have employees, workers compensation cover. A legitimate operator will hand these details over without hesitation. If they stall or get defensive, walk away.

Three quotes is a solid minimum for any concrete job over a few thousand dollars. More importantly, make sure all three are quoting on the exact same scope. If one contractor prices a 50 mm slab with mesh and another prices 100 mm with F82 mesh and a vapour barrier, you are not comparing anything meaningful.

A proper written quote should include:

• Business name, ABN and licence number
• Scope of work in plain language (area in square metres, thickness, finish type, reinforcement details)
• What is explicitly excluded, for example, tree root removal or council crossover permits
• Timeline and payment schedule
• What happens if ground conditions differ from expectation

General market rates in 2026 run roughly $65 to $90 per m² for plain broom or trowel finish, $100 to $150 per m² for exposed aggregate or decorative finishes, and $80 to $110 per m² for reinforced structural slabs. A typical 40 to 50 m² single driveway commonly totals somewhere between $4,000 and $9,000 once you factor in excavation, formwork, access and finish. These are rough guides only. Your site conditions, finish choice and location will all move the number. Always get a written quote specific to your job before committing to anything.

Before Work Starts

A contractor who cannot produce a licence number, wants full payment upfront, or refuses to give you a written contract is not someone you should hire. Period. Legitimate concreters ask for a reasonable deposit, typically 10 to 30 per cent, with the balance due on practical completion or in staged payments tied to progress.

Be cautious if the quote arrives with extreme urgency attached to it. Pressure tactics like "this price is only good today" or "I have a concrete truck booked for tomorrow" are classic manipulation. A trustworthy operator understands that you need time to review paperwork.

Once Work Is Underway

Keep an eye on what actually turns up. Watered-down concrete mixes are a known issue on dodgy jobs. The concrete should arrive in a drum truck with a delivery docket showing the mix design and cubic metres ordered. Ask to see that docket. If concrete is being mixed on site in a small drum, make sure the ratios look right and ask questions.

Watch for very thin pours. A standard residential driveway is typically 100 mm thick with mesh reinforcement. If the formwork looks shallow, raise it before the pour, not after.

• No delivery docket for readymix concrete
• Workers who seem unfamiliar with basic processes
• Formwork that looks too shallow for the job type
• No curing compound or wet hessian applied after the pour
• Pressure to hand over final payment before the job is inspected and signed off

If you have paid money and the contractor has disappeared or the work is clearly defective, act quickly. The longer you wait, the harder recovery becomes.

Step one: Document everything. Photographs, text messages, emails, receipts, and the original quote. Write a timeline while it is fresh.

Step two: Lodge a complaint with your state's building regulator. In Queensland that is the QBCC, in NSW it is Fair Trading, in Victoria the VBA. Most have formal dispute resolution processes and the ability to take disciplinary action against licensed operators. Unlicensed operators can be referred to the regulator and, in serious cases, to police.

Step three: If the amount in dispute warrants it, consider the relevant state civil and administrative tribunal (NCAT in NSW, VCAT in Victoria, QCAT in Queensland). These are relatively low cost and do not always require a lawyer.

Step four: If you paid by credit card, contact your bank about a chargeback. Cash payments are much harder to recover, which is exactly why scammers prefer them.
