I think my question isn't that clear sorry. I won't be building it in the winter, I am just wondering if the cold winters in the future will cause any damage to it, otherwise I'll go with a wood deck.The first thing to consider is if the ground is frozen. You don’t want to place concrete on a frozen surface. Heating blankets can be used to get rid of frost but at great expense. If the ground is not frozen and temps will be a few degrees below freezing the heat of hydration of the concrete will keep it warm. You could have 1 or 2 percent accelerator put in the concrete to make it heat and cure faster. After it is cast and finished it should be covered with blankets to keep it warm. In weather colder than a few degrees below freezing the area can be enclosed and heated with a salamander. Concrete is possible in any weather but the price goes up exponentially as the temperature drops.
Most likely. Companies adjust their mix for the area it is being used.Hi. I am thinking of making a concrete patio for my new cottage, but I'm wondering if the extreme winters of Quebec will damage it in the future. Will controlled joints be enough to prevent cracking?
