ᐅ Leave the concrete slab exposed over the winter months

Hello,

we will start with the foundation slab soon (October–November), but the prefabricated house can only be delivered next year. Our goal is to move in by March or at the latest April. What makes more sense, and what are the advantages or disadvantages of starting the foundation slab this year but having the house delivered next year?
Would it be better to do the foundation slab at the end of January or beginning of February?
I am also open to alternative suggestions.
Regards

Well, what is there is there. If it gets properly frosty in January/February (not uncommon for that time of year), it will be a tight squeeze. Overall, it’s going to be tight anyway. What exactly does "can only be delivered next year" mean? Even with a prefabricated house, the interior work takes time (floor screed drying, etc.).

The prefabricated house will definitely be built this year. Does the foundation slab get affected by the cold months?
Regards

No, if it is completed before the freezing season, it can remain over the winter. If the house is built on top later, it must also withstand the winter.

However, ideally, there will be no water on it that could penetrate pores and freeze there...
I’m not sure if this poses a risk, so it’s better to consult a professional...

In the past, the cellar or shell structure was deliberately built in autumn so it could dry out over the winter (which is usually a drier season). I believe the same applies to a concrete slab foundation.

I definitely wouldn’t take the risk of scheduling the slab foundation for January and then being unable to proceed because of too low temperatures. What you have is what you get!
