Pro Concreting Adelaide is what you end up typing at 11pm, after the third quote lands in your inbox and none of them agree Pro Concreting Adelaide. One quote says four grand. Another says eleven. Same driveway. Same dirt. So what's going on?
Why every quote looks different
Concrete looks simple. Grey stuff, wet, then dry. But the real money lives underneath it. Adelaide has reactive clay soil that puffs up in winter and shrinks back in summer, and a slab poured without respect for that will crack like a dropped biscuit. A bargain job skips the prep work. A good one spends half its time before any concrete arrives.
Ask what's going under the slab. Compacted road base? How deep? Is there a moisture barrier? If all you get is a shrug, keep your wallet shut.
Mesh, depth and the dull stuff
Reinforcement sounds boring until a diagonal crack splits your brand-new patio. Steel mesh or bar sits inside the pour and holds everything together when the ground decides to wander. Thickness matters too. A garden path can get away with 75mm. A driveway taking a ute and a caravan wants 100mm minimum, and often more around the edges.
Then come the control joints. Those neat lines cut into the surface? Not decoration. They tell the concrete where to crack, so it does it politely, in a straight line, somewhere nobody trips over it.
Old slab, new slab, or neither one?
Got something ugly already sitting there? Breaking it out costs money, and hauling the rubble away costs a bit more. Sometimes resurfacing does the job. Sometimes it's good money chasing bad. A decent contractor will tell you which, even if it means a smaller invoice for them. That's the one you want.
Timing, weather and a little patience
Pour on a 40-degree January afternoon and the top dries off before anyone can finish it. Pour in a cold, soggy week and curing drags on forever. Good crews eye the forecast like farmers. They'll ring you and say, "Not Thursday, mate. Friday." Say thanks.
Then the waiting begins. Foot traffic after a day or two. Cars after about a week. Full strength around four weeks. I know, I know. You want to park on it tomorrow. Don't.
Finishes that don't turn into skating rinks
Exposed aggregate, broom finish, coloured, stamped. Everyone loves a smooth, glossy look until the first wet morning, when a grandparent shuffles to the letterbox in slippers. Texture grips. Pick the finish for how you'll actually live on it, not for how it photographs.
Questions worth asking before you sign
Who's on site, the person you met or a stranger with a shovel? Is the quote itemised? What happens if it cracks in year one? A tradie who believes in their own work answers fast and with specifics. Hesitation says plenty.
Check the licence and the insurance too. Ten minutes of homework buys you years of peace.
