Concrete may look hard long before it is ready for a car. It gains strength over time, and the first days also matter for the surface finish. Ask your installer for a written date for foot traffic, ordinary cars and any heavier vehicle. Follow that advice for the actual mix, weather and site.
Plan for the driveway being closed
Arrange alternative parking before the pour. Think about access for bins, deliveries, children and anyone with mobility needs. If this is your only entrance, discuss a temporary route with the contractor before work begins, especially when an old driveway is being removed.
Why timing varies
Temperature, moisture, mix design, slab specification, finishing and curing method all influence the schedule. Walking on a surface, parking a family car and bringing in a heavy removal truck are different loads. Do not take an early foot-access date as permission to drive. Keep vehicles off the edges unless the installer says they are ready.
Curing is more than waiting for the surface to dry. It protects fresh concrete from losing moisture too quickly while strength develops. Cement Australia’s slab guide describes protecting and moist curing fresh concrete for seven days; the installer should specify the right method for your finish.
Get the instructions before the pour
Ask when pedestrians can enter, when you can drive and park, whether heavier vehicles need a longer wait, and who manages curing or sealing. Keep those instructions with the job paperwork. If rain or unusually cool or hot weather changes the schedule, check again. See the driveway service page or driveway thickness guide while planning.
Can I park as soon as I can walk on it?
No. Vehicle loading is much greater than foot traffic. Wait for the installer’s specific vehicle-access approval.
Does a surface that looks dry mean it is cured?
No. Visible drying is not a reliable measure of strength or readiness for vehicles.
