Thickness of the concrete slab – Thicker slabs will take longer to dry obviously. The primary reason is because water trapped deeper in the concrete will not be impacted by other elements like solar load and ambient temperature as quickly as water that was closer to the surface.

How many inches of concrete do I need for a driveway?

How long should concrete cure before putting weight on it?

No single answer exists for how long a deck footing needs cure before building the deck on top of it.
