Pro Concreting Adelaide is what you end up typing at 11pm, after the third quote lands in your inbox and not one of them matches Pro Concreting Adelaide. One says four grand. Another says eleven grand. Same driveway. Same dirt. So what's going on?
Why the quotes never match
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 burns half its hours before a single truck turns up.
Ask what's going under the slab. Compacted crushed rock? 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 dull until you're staring at a diagonal crack across your brand-new patio. Steel mesh or bar sits inside the pour and keeps things together whenever the ground decides to wander. Thickness counts as well. A garden path gets away with 75mm. A driveway that carries a ute and a caravan wants 100mm at the very least, often more along the edges.
And then there are control joints. Those tidy lines sawn into the surface? Not decoration. They tell the concrete where to crack, so it does so politely, in a straight line, where nobody trips over it.
Keep the old slab or start fresh?
Already got something ugly sitting there? Breaking it out costs money, and hauling the rubble away costs a bit more. Sometimes a resurfacing job does the trick. Sometimes it's throwing good money after bad. A decent contractor will say which, even if their invoice shrinks. 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 and say, "Not Thursday, mate. Friday." Say thanks.
Then the waiting begins. Foot traffic after a day or two. Cars after roughly a week. Full strength at about four weeks. I know, I know. You'd love to park on it tomorrow. Don't.
Finishes that won't become skating rinks
Exposed aggregate, broom finish, coloured, stamped. Everyone loves a smooth, glossy look until the first rainy morning, when a grandparent heads for the letterbox in slippers. Texture grips. Pick the finish for how you'll actually live on it, not for how it photographs.
What to ask before signing anything
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 backs their own work answers quickly and with detail. Hesitation says plenty.
Check the licence and the insurance too. Ten minutes of homework buys years of peace.
