If concrete sets too quickly in hot weather it can cause shrinkage and cracking.
To prevent this from happening, dampen the gravel base with water and use cool water when mixing the concrete.
If creating a concrete slab is on your list of projects for this summer, you already know you’ll work up a little sweat. But did you know it’s important for the concrete to stay cool, too?
Dampen the gravel base before you start, to cool it down, and use cool water to mix the concrete. This will prevent the new concrete from curing too quickly. By slowing down the curing process you’ll reduce the chances of shrinkage or cracking and ensure a better result.
