Guides › Drive-on time for new concrete
As a rule, you can walk on a new concrete driveway after about 24 hours and drive a normal car on it after around 7 days, once it has gained most of its early strength. Heavier vehicles like a boat trailer, caravan or truck are best kept off for longer, and your concreter will give you a firm figure based on the mix, the thickness and the weather on the day.
It is the question every homeowner asks the moment the crew packs up, and the honest answer is that concrete keeps getting stronger for weeks, but the practical milestones are what you need. Here is how curing actually works, and how the Coast climate changes the timing.
These are guides, not promises. A thicker slab, a different mix or cooler weather all shift the numbers, which is why the concreter who poured it is the person to confirm your exact timeframe.
Concrete does not dry out, it cures, through a chemical reaction between the cement and water that needs moisture to keep going. That single fact explains most of what the Coast climate does to a fresh pour.
Humidity helps. The high humidity of a Sunshine Coast summer is genuinely good for curing, because it slows the surface from drying out too fast and lets the reaction run properly. Damp coastal air is friendlier to a curing slab than the dry inland heat you get further west.
Heat cuts both ways. Warm Coast temperatures speed the initial set, so the surface feels hard quickly. That is a trap. The top feeling solid does not mean the slab underneath has the strength to carry a car, and driving on it early is one of the few ways a homeowner can genuinely wreck an otherwise good driveway. In peak summer heat a good crew will pour early in the morning and cure the surface to keep the strength in the concrete rather than losing it to a fast, hot set.
The wet season is the real risk. The Coast has a distinct wet season, roughly December to March, with heavy afternoon storms. A downpour on a fresh, unset pour can pit or wash the surface and weaken the top layer, and saturated ground makes the whole job harder. Light rain after the surface has set is usually harmless and can even help curing, but a storm on a green slab is not. That is why pours here are timed around the forecast and the surface is protected on the day. For more on timing a pour around the seasons, see our guide on the best time of year to pour concrete on the Coast.
There is not much a homeowner needs to do, but a few things help. Keep vehicles off until you are told it is right, even if the surface looks ready. Keep sprinklers, downpipes and pool overflow from pooling on a fresh slab. If the concreter asks you to keep the surface damp or leaves a curing membrane on it, leave it be. And do not drop a heavy skip, trailer or building materials on a new slab in the first couple of weeks. Patience in the first week is what buys you a driveway that lasts decades.
Curing time is only the last step. A slab that carries a car well after seven days is really the product of the base, the steel and the joints that went in before the pour. Our concrete driveways page walks through that full build, and if you are weighing up a shed or house slab the same curing rules apply. If an old slab is failing rather than curing, resurfacing may be an option worth pricing.

Yes, and mostly for the better. Concrete cures by a chemical reaction that needs moisture, so the high humidity of a Sunshine Coast summer helps keep the surface from drying out too fast and can actually assist curing. The catch is that pouring in the wet season risks a storm marking or washing the fresh surface, so timing and protection still matter.
Not really. Heat speeds the initial set so the surface feels hard quickly, but the slab keeps gaining strength for days underneath. Driving on it early because the top feels solid is one of the few ways a homeowner can genuinely damage a good driveway, so stick to the timeframe your concreter gives you.
Light rain after the surface has set is usually fine and can even help curing, but a heavy wet-season downpour on a fresh, unset pour can pit or wash the surface and weaken the top layer. That is why Coast pours are timed around the forecast and the surface is protected on the day, especially through the December to March storm season.
