Concreters: Three Tactics That Beat Slow-Paying Builders

You’ve finished the pour. The concrete’s cured. The builder’s happy with the finish. But the invoice sits unpaid for weeks, then months. You’re a concreter, not a bank—you shouldn’t be funding their project.

Slow payment isn’t just frustrating; it threatens your cash flow and your ability to take on the next job. The good news: Australian Security of Payment legislation exists specifically to stop this. It gives you real teeth, and you don’t need a lawyer to use them.

Here are three practical tactics that work for concreters owed money by builders and head contractors.

1. Document everything in writing, right from the start

Before you pour a single cubic metre, get the payment terms in writing. Not a text message. Not a handshake. A signed contract or email chain that both parties agree to.

This matters because when a dispute happens, the Security of Payment Acts in every state require you to prove a few basic things:

• What work you did
• What you’re owed
• What the agreed payment terms were
• That you served the claim properly

Without documentation, you’re arguing from memory. With it, you’re arguing from fact. Builders know this, which is why they sometimes drag their feet—hoping you’ll forget, give up, or accept a smaller payment.

Keep photos of the work as you go. Save emails and messages. Write down the date and scope of each pour. When you send an invoice, include the contract reference or agreed terms. This isn’t legal advice—it’s just good business sense that happens to make the law work for you.

2. Send a formal payment claim under the SOP Act

This is where most tradies lose momentum. A casual invoice gets ignored. A formal payment claim under your state’s Security of Payment legislation gets attention.

Why? Because it triggers a legal process with real deadlines that neither you nor the builder can ignore.

In NSW, for example, under the Security of Payment Act 1999, once you serve a valid payment claim, the builder (the respondent) has exactly 10 business days to issue a payment schedule. If they don’t, they lose the right to dispute the amount. In Queensland, the Building Industry Fairness (Security of Payment) Act 2017 sets similar timeframes. Victoria’s Security of Payment Act 2002, South Australia’s Building and Construction Industry Security of Payment Act 2009—they all work on the same principle. You make a claim, they respond or lose ground.

A payment claim isn’t a polite request. It’s a formal demand that starts a statutory clock.

You can file a payment claim yourself in under 10 minutes using online tools, or draft one using your state’s legislation as a template. The form is straightforward: job details, work completed, amount claimed, GST, date served. The builder can’t argue the process—they can only argue the facts, and they have to do it in writing within the deadline.

3. Know when to escalate to adjudication

If the builder issues a payment schedule disputing your claim, you have a choice. You can negotiate, or you can push for fast-track adjudication.

Adjudication is the legal hammer. Here’s how it works:

1. You lodge an adjudication application with an agreed or appointed adjudicator
2. The adjudicator reviews both your claim and the builder’s response
3. They make a binding decision within 10 business days (sometimes longer if agreed)
4. The builder has to pay the adjudicated amount or face legal action

This process exists because Parliament decided construction workers shouldn’t wait 12 months for a court hearing to get paid for work they’ve already done. Adjudication is fast, cheaper than litigation, and designed to protect people like you.

Many builders choose to pay or settle rather than face adjudication, because the process is formal, documented, and enforceable. But that’s their choice to make, not a guarantee. What matters is that you have the option—and most tradies don’t realise how powerful that is.

Why these tactics work

None of these approaches require you to hire a lawyer or spend thousands of dollars. They work because they’re built into Australian law and designed to level the playing field.

A builder who ignores a casual invoice might ignore 10. But one who receives a formal payment claim under the SOP Act knows the rules have changed. You’re no longer asking for your money—you’re claiming it, on the record, with statutory backing.

The concrete doesn’t get poured again if you don’t get paid. That principle is what the Security of Payment Acts protect. Use them.

Start now: Review your last three invoices. Are they backed by signed contracts or written terms? If not, fix that for your next job. If you’re owed money now, gather your documentation and consider whether a formal payment claim makes sense. It costs a flat fee and takes minutes to lodge.
