Is a Concreting Business a Good Investment in Australia?
A concreting business in Australia can be a genuinely good investment — but only if you buy the right one. The industry has strong, consistent demand, decent margins when run well, and a clear path to systematising with the right tools. It also has some features that will hurt a poorly prepared buyer: capital intensity, weather sensitivity, and an almost universal key-man problem where the owner IS the business.
Here's how to think about it if you're considering buying an existing concreting operation.
How profitable is a concreting business in Australia?
A well-run concreting business in Australia typically generates EBITDA margins of 12–20% on annual revenue. The ATO publishes benchmark data for concreting services that gives you a useful reality check — businesses falling well outside those benchmarks either have undisclosed add-backs or are genuinely underperforming.
Revenue depends heavily on what type of concreting work the business does:
- Residential slabs and driveways — High volume, lower ticket size ($5,000–$30,000 per job), competitive pricing, but repeatable and forecastable.
- Commercial and civil work — Higher ticket ($50,000–$500,000+), longer payment cycles, more tender-based, higher equipment requirements.
- Decorative and specialty concrete — Exposed aggregate, polished concrete, feature walls — often better margins but smaller market.
A typical small-to-medium concreting business with 3–8 employees in Australia turns over $800K–$3M a year. The owner-operator who runs the crews and quotes jobs themselves might clear $150K–$350K in combined wages and profit — before you factor in what the business is actually worth as an asset.
The buy-vs-start question
Most of the content online about concreting businesses is about starting one. That's a different proposition entirely.
Starting a concreting business requires building your own reputation, acquiring clients from scratch, assembling plant and equipment, and hiring or subcontracting reliable concreters. That takes 2–4 years to reach any meaningful size — assuming you have trade skills yourself, which most corporate buyers don't.
Buying an existing operation gives you something most people underestimate: a book of clients who already know the business, an established supplier chain, equipment that's (hopefully) maintained and running, and crew who know the work. You're paying for all of that. The question is whether you're paying the right price.

What drives demand for concreting in Australia?
Concreting in Australia benefits from several tailwinds:
Residential construction remains strong across most major capitals and regional centres. Slabs, driveways, paths, and retaining structures are recurring work tied to housing activity.
Infrastructure spending — federal and state governments have maintained significant capital works programs across roads, bridges, and public amenity projects. IBISWorld tracks Australian concreting services as a sector that has broadly grown alongside this infrastructure pipeline.
Non-residential development — commercial, industrial, and mixed-use construction continues in urban fringe areas of Sydney, Melbourne, Brisbane, and Perth.
The cyclicality matters though. A concreting business that derives most of its revenue from residential new builds is exposed to housing market slowdowns. A business more weighted to maintenance, renovation, and government work is more defensive.
What are the real risks?
Equipment is the hidden problem
Concreting is capital-intensive. A concrete pump can cost $100,000–$400,000. Bobcats, trowel machines, vibrators, trailers, and a fleet of utes add up fast. When you're buying a business, you're also buying the equipment — and if that equipment is aging or poorly maintained, you could face large replacement costs within 12–24 months of settlement.
This is the single most common surprise buyers of concreting businesses face (I've heard versions of this from three separate brokers in the past year). Budget 10–15% of the business's purchase price for a proper equipment assessment by an independent valuer. It's not optional.
Key-man risk is almost universal
The typical concreting business founder is the person who quotes, supervises, troubleshoots, and maintains relationships with the main clients and suppliers. When they leave, some of that value leaves with them.
That doesn't mean you shouldn't buy — it means you need a proper handover period, ideally 6–12 months, and you need to understand which clients will stay regardless of who owns the business. Read about owner dependency risk before you proceed.
Weather and seasons
Concreting is affected by rain, extreme heat, and frost. This creates lumpy cash flow — particularly in winter in southern states. If you're looking at 12 months of financials and they don't cover a full seasonal cycle, be careful. You want to see at least two full years, ideally three, to understand the pattern.
Subcontractor vs employee model
Some concreting businesses run primarily on subcontractors — they can flex workforce up and down but pay a premium and carry less control over quality. Businesses running their own crew have lower margins on small jobs but better quality control on larger ones. The structure matters for how you manage the business post-acquisition.
What to look for when evaluating a concreting business to buy
Revenue by client — A business where one commercial client represents 30%+ of revenue is fragile. You want to see spread.
Revenue by job type — Understand what proportion is residential vs commercial vs government. Different cycles, different risks.
Equipment register and condition — Get an independent valuation. Don't rely on the seller's depreciation schedules.
Crew retention — Are the concreters employees or subs? How long have they been there? Would they stay under new ownership?
Licensing — Concreting businesses in most states require contractor licences. Verify these are current and transferable.
Work-in-progress pipeline — What's already quoted and contracted? A business sold in autumn with a full summer pipeline ahead is very different to one sold with an empty book.
For a structured approach to evaluating any trades business, I've put together a Trades Business Assessment Checklist that covers these questions in a format you can work through with the seller.
What do concreting businesses sell for?
Small concreting businesses in Australia typically sell at 2–3x seller's discretionary earnings (SDE) for owner-operated businesses. Larger operations with managers in place and documented processes — where the owner isn't the main operator — can achieve 3–4x EBITDA or more.
Factors that push the multiple higher:
- Long-term commercial contracts or council relationships
- Strong second-tier management (a foreman or estimator who'll stay)
- Newer, well-maintained equipment fleet
- Diversified client base with no concentration risk
Factors that compress the multiple:
- Heavy owner dependency
- Aging equipment with near-term capex required
- Concentration in a single client or project type
- No formal systems or quoting process
For EBITDA multiples for trades businesses in Australia more broadly, there's a full breakdown of how buyers and sellers negotiate these numbers across different service categories.
Is it right for someone coming from corporate?
Probably — with some caveats.
Concreting businesses need competent management more than they need a tradesperson. If you can systemise quoting, improve scheduling, retain crew, and maintain client relationships, you don't need to know how to pour concrete. Several people have done exactly this: acquired a small concreting operation with a good reputation, installed proper job management software, standardised the quoting process, and grown revenue meaningfully in the first 12–18 months.
The difficulty is the hands-on nature of the first six months. You'll be on sites more than you expect, translating between a world you know (business management) and a world you don't (a crew who've been doing this for 20 years and have no patience for spreadsheets). That's the real transition challenge.

FAQs
Is concreting a profitable business in Australia? A well-run concreting business in Australia typically generates EBITDA margins of 12–20%, with owner-operators earning $150K–$350K combined from wages and profit depending on business size. Profitability depends heavily on job mix, equipment utilisation, and whether the business has moved beyond pure owner-operator dependency.
How much does a concreting business make in Australia? A small-to-medium concreting business with 3–8 staff typically turns over $800K–$3M annually. Net profit (SDE) for an owner-operated business commonly sits between $120K and $350K after adding back the owner's wage.
What are the risks of buying a concreting business? Key risks include aging or poorly maintained equipment (can require significant near-term capex), high owner dependency (the seller's relationships leaving with them), weather-related revenue volatility, and concentration risk if one or two large clients represent the bulk of revenue.
How much does a concreting business sell for in Australia? Small concreting businesses typically sell at 2–3x seller's discretionary earnings. Businesses with management structures, long-term contracts, and documented processes can achieve 3–4x EBITDA. Equipment condition and client diversity are the two biggest factors affecting where on that range a business lands.
Do you need trade skills to run a concreting business? Not necessarily. Corporate buyers with management skills have successfully acquired and grown concreting businesses by improving systems, scheduling, and client management. The challenge is the transition period — expect a hands-on first six months while you learn the operational side.
