Pro Concreting Adelaide is the kind of search you type at 11pm, after the third quote lands in your inbox and not one of them matches https://proconcretingadelaide.com/. One says four grand. Another says eleven grand. Same driveway. Same dirt. So what gives?
Why the quotes never match
Concrete looks simple. Grey sludge, wet, then dry. But the true cost lives underneath it. Adelaide has reactive clay soil that swells in winter and shrinks 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 beneath the slab. Compacted road base? How deep? Is a moisture barrier going in? 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 holds everything together when the ground decides to wander. Thickness matters too. A garden path can get away with 75mm. A driveway that carries a ute and a caravan wants 100mm at the very least, often more along 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 so politely, in a straight line, where nobody trips over it.
Old slab, new slab, or neither?
Got something ugly already sitting there? Breaking it out costs money, and carting the rubble off costs a little more. Sometimes a resurfacing job does the trick. Sometimes it's throwing good money after bad. A decent contractor will tell you which, even if it means a smaller invoice for them. That's your person.
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 crawls along forever. Good crews eye the forecast like farmers. They'll ring and say, "Not Thursday, mate. Friday." Say thanks.
Then comes the waiting. Foot traffic after a day or two. Cars after about a week. Full strength around four weeks. I know, I know. You'd love to park on it tomorrow. Don't.
Surfaces that don't double as ice 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 turns up 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 insurance as well. Ten minutes of homework buys you years of peace.
