After the concrete is poured, it typically takes 24 to 48 hours for the surface to cure enough to be walked on. However, the concrete will still be quite soft and vulnerable during this initial curing period. It's important to keep the area clear of foot traffic as much as possible to prevent damage.
Once the initial 24 to 48 hour curing period has passed, the concrete will continue to strengthen over the next 7 to 10 days. During this time, the driveway can support the weight of passenger vehicles, but it's best to avoid parking or driving on it as much as possible. For heavier vehicles like large pickup trucks, RVs, or commercial trucks, it's recommended to wait a full 30 days before using the driveway to ensure the concrete has fully cured and hardened. Rushing use of the driveway before the proper curing time can lead to cracking, pitting, or other damage.
