Regarding the basement expansion and foundation slab of our single-family house, some initial questions and uncertainties have come up.
Has anyone here had experience with a wooden basement ceiling (foundation slab)?
A bit more detail:
The basement shell is made of concrete elements. The interior basement walls are planned to be constructed from timber system elements. The basement ceiling (foundation slab) is also intended to be built as a wooden structure.
Since we have never heard of such a combination before and found nothing on the internet, we are quite unsure if this is a good approach?!
Does anyone possibly have experience with this kind of basement construction? 😕

It is important to understand the risks and potential damage that wooden components in this basement layout might face: Basement interior walls? No water, no earth pressure – if everything is done correctly, meaning the basement slab is properly sealed, nothing should happen that would argue against using wood.
The basement ceiling (not the “slab,” as a slab rests on the ground) presents even fewer risks. There is no direct contact with water from the outside, and certainly none from below.
If done right, there is no obstacle to this method of basement construction. The uncertainty arises from assuming poor sealing of the basement slab; if water penetrates here, wooden walls will be more affected than interior walls made of concrete or masonry with regard to material impact. However, this would be a serious construction defect by the builder and has nothing to do with the use of wood as a building material. A damp basement always causes problems and extra costs—and it is always due to execution and/or planning errors, regardless of the building material used.
