How to Prepare for Your Concreting Call
Get Ready Before You Pick Up the Phone
Preparing for your concreting call takes about ten minutes of honest thinking beforehand. Know roughly what you want, where it's going, and what your block looks like — and the conversation will be faster, more accurate, and far more likely to produce a quote you can actually use.
That's the short answer. Here's the longer version.
Know What You're Actually Asking For
Concrete work sounds like one thing until you start talking to a contractor. "A slab" could mean a garage slab, a patio slab, or a shed base, and each one has different reinforcement requirements, finish options, and drainage considerations.
Before you call, be clear on which of these you're after:
- A new driveway (replacing an old one, or pouring where there was none)
- A shed or garage slab (typically reinforced, with a beam edge)
- An outdoor entertaining area (patio, alfresco, poolside platform)
- A pathway (side access, front entry, garden walkway)
- Repairs or resurfacing (cracks, spalling, surface deterioration)
- A decorative finish like exposed aggregate over any of the above
You don't need to know the exact spec. But knowing the category saves a lot of back-and-forth on the call and helps us give you a tighter estimate right away.
Measure the Area (Roughly Is Fine)
You don't need a laser measure or a surveyor. Walk the space and count your paces. One adult pace is roughly 750mm to 800mm, so twenty paces is about 15 metres. Multiply length by width and you have an approximate square metreage.
For driveways, also think about width. A single car driveway in the western suburbs is typically 2.8m to 3.2m wide. A double is usually 5.5m to 6m. If your driveway narrows through a gate or past a corner, note that too.
For a patio or entertaining slab, sketch it on paper if the shape is irregular. An L-shape, for example, is just two rectangles added together.
Why does this matter? Concrete is priced largely by area and volume. An estimate based on "about 40 square metres" will be more useful to you, and more accurate from our end, than "I'm not sure, maybe medium-sized?"
Think About Your Block and Access
This is the part most people skip, and it's the part that most often affects the final price.
Brisbane's Inner West, including suburbs like Chelmer, Graceville, Indooroopilly, and Taringa, has a lot of older residential blocks with quirky access. Narrow side passages, mature trees with root systems, steep street grades, and original Queenslander stumps create real logistical questions.
Consider these before your call:
- Street access for a concrete truck. A standard agitator truck needs roughly 3 metres of clearance and a place to position. If your driveway approaches from a busy road or a narrow street (St Lucia and Sherwood have several), a pump truck may be needed, which adds cost.
- Existing concrete or demolition. If there's old concrete to remove, that's a separate cost. Know whether it's there and roughly how thick it might be.
- Trees and roots. A big poinciana or fig near your proposed slab isn't necessarily a problem, but it's a conversation worth having upfront. Root intrusion under slabs is a known issue across the western suburbs.
- Slope and drainage. Concrete slabs need to drain somewhere. If your yard already has drainage challenges, flag that early.
- Soil type. Much of Inner West Brisbane sits on reactive clay. This affects subbase preparation and reinforcement requirements. You probably won't know your exact soil classification, but if you've had cracking issues with existing concrete, mention it.
None of this is meant to alarm you. It's just useful context that helps us give you an honest scope rather than a cheap number that blows out later.
Have a Budget Range in Mind (Even a Loose One)
You don't have to name a number first. But knowing your rough budget range actually helps you, not just the contractor.
Typical concreting jobs in our area run somewhere between $1,500 for a small path or repair job and $15,000 for a larger driveway or garage slab with decorative finishes. Where your project lands depends on area, thickness, reinforcement, finish type, and access complexity.
If your budget is $3,000 and the job realistically needs $6,000 of work, better to know that early and either adjust scope or timeline. If you have flexibility and want to understand what a premium exposed aggregate finish adds versus a plain broom finish, that's a useful conversation too.
The trade-off is real: a plain broom finish costs less upfront and is perfectly functional. Exposed aggregate costs more (typically $20-$40 per square metre extra, as a rough guide) but it hides dirt better, adds texture, and, honestly, looks sharper on a Queenslander streetscape. Neither choice is wrong.
Prepare a Few Practical Questions
A good concreting call is two-way. You're also assessing whether this is someone you want working on your property. Here are questions worth asking:
- What's included in the quote? (Base preparation, formwork, reinforcement, finishing, sealing?)
- What finish options are available for this job type?
- How long before I can drive or walk on it?
- What drainage provision is included?
- Do you handle council requirements or permit issues if they apply?
- What does your warranty or workmanship guarantee cover?
You're not being difficult by asking these. You're doing exactly what anyone spending several thousand dollars should do.
On the permit question specifically: most residential concrete driveways in Brisbane City Council's jurisdiction don't require a formal development approval, but a vehicle crossing permit (or approval from BCC for altering the kerb) may apply depending on your situation. A contractor working regularly in Chelmer, Corinda, Moorooka, and surrounding suburbs should know this without blinking.
A Word on Timing and Seasons
Brisbane's climate is genuinely relevant here. Concrete placed in extreme heat cures faster, which sounds good until you realise rapid curing increases the risk of surface cracking. Summer in the western suburbs, with afternoon temperatures regularly pushing into the mid-30s, means experienced contractors time pours for early morning and adjust their mix accordingly.
The wet season (roughly November through March) brings another consideration: rain on freshly poured concrete before it has set is bad news. A good crew watches the Bureau of Meteorology forecast carefully and won't pour if there's a realistic risk of afternoon storms.
If you're planning a project for summer, don't let that stop you, but do ask your contractor how they handle hot weather pours. It's a reasonable question and a revealing one.
Before You Call
You've done the useful work if you can answer these five things:
- What type of concrete job is it?
- Roughly how big is the area?
- Are there any obvious access, tree, or drainage complications?
- Do you have a rough budget range in mind?
- Is there a timeline pressure (new garage going up, event at the house, etc.)?
You don't need a complete brief. Contractors ask questions too, and a site visit will clarify plenty. But arriving at the conversation with this grounding means you're less likely to get a vague quote, less likely to be surprised by scope additions, and more likely to feel confident about what you're agreeing to.
If you're in Chelmer, Graceville, Indooroopilly, Sherwood, Yeronga, or anywhere nearby and you'd like a straight conversation about a concrete job, give us a call. Come with your rough measurements and a description of what you're after, and we'll take it from there.
