Home › Guides › How Long Before You Can Drive on Concrete
As a general rule, you can walk on a new slab after about 24 hours and drive a car on it after around 7 days. Concrete keeps gaining strength for weeks after that, but roughly a week is enough for a domestic driveway to carry vehicle loads. In Townsville the wet season and the build-up heat both change how curing plays out, so the honest answer is always the time your concreter gives you on the day.
These are guides, not guarantees. The mix, the slab thickness and the weather all shift the times, which is why a concreter gives you a specific figure for your job rather than a number off a website.
Concrete does not dry, it cures. It needs to hold on to moisture while a chemical reaction builds its strength. That single fact explains why the dry tropics pull curing in two opposite directions depending on the season.
The wet season helps, but adds risk. Through the December to March monsoon, the high humidity actually assists curing, because it slows the moisture loss the slab needs to keep. The danger in the wet is not the cure, it is the sky. A sudden downpour landing on a fresh, unset surface can wash it out and ruin the finish, and flooding around a low block can undermine the slab before it has set. That is why pours are scheduled carefully around the storms, and why the wet season is a poor time to pour if it can wait.
The build-up heat works against you. Through the hot, dry months, especially the build-up from October to December, extreme heat speeds the set and pulls moisture out of the slab too fast. Lose that moisture too early and the surface can end up weaker and prone to shrinkage cracking. Concreters counter this with early-morning pours before the day heats up, and active curing such as keeping the surface damp or covered, so the strength stays in the concrete rather than evaporating into a hot, dry afternoon.
If you are getting concrete poured, these pages cover the jobs where curing time matters most:
Timing the pour itself matters too. See our guide to the best time of year to pour concrete in Townsville.

As a general rule, you can walk on a new slab after about 24 hours and drive a car on it after around 7 days. Concrete keeps gaining strength for weeks, but roughly a week is enough for a domestic driveway to carry vehicle loads. Your concreter will confirm a firm time based on the mix, thickness and the weather on the day.
The high humidity of the wet season actually helps curing, because it slows the moisture loss that concrete needs to gain strength properly. The risk in the wet is not curing, it is a downpour landing on a fresh slab or flooding around it, which can wash out the surface. That is why pours are scheduled carefully around the storms.
Yes. Extreme heat in the build-up speeds up the set and pulls moisture out of the slab too fast, which can weaken the surface if it is not managed. Concreters counter this with early-morning pours before the day heats up and active curing, so the strength stays in the concrete rather than being lost to the air.
It is not worth it. Driving on a slab before it has gained enough strength can crack it or leave permanent marks, and there is no repair short of replacement. Wait the time your concreter gives you. A week of patience protects a driveway that should last decades.
