ᐅ Thermal bridge due to insufficient insulation of the foundation slab?

Hello dear community,

Things are getting serious now. We received a call that the foundation and floor slab will be completed this week, and here they already are.

A friend of ours (a former construction manager) pointed out that there might be a thermal bridge at the lower wall because the foundations are not insulated and the insulation on the floor slab only extends 20cm (8 inches) into the ground.

After checking with the site manager, we were told this is not a problem.

Do we need to take any action here?
What is your opinion on the possible thermal bridge?

Thank you very much.

The first course/bed joint will be built with thermally insulating blocks. You should ask the site manager about that.
That’s fine as it is.

Don’t get too worried... Many aspects of your house could probably be done better/higher/faster/farther. But not nearly everything is critical!
Did you hire a professional company for the construction?
Have you reviewed the plans and the concept before starting the work?

(Content-wise: See #2. In my opinion, this issue is also relevant for the interior walls. Ask about the “kimmsteine” or the “kimmschicht.” However, even if this applies, the house will be warm and will consume relatively little energy. With proper execution, damage in this area is not to be expected.)

Thank you very much for the responses.

We will inquire about the cavity barrier again.

Our concern is actually less about heat loss and more about the risk of mold, as water tends to accumulate in the cold areas.
