Hello!
I've been reading in the forum about many variations of basements, and I can't quite find my version so I'm throwing out a couple of questions:
I have a newly re-drained basement/ground floor - Construction from the inside out - leca/platon/jackon (insulation up to ground level).
In the basement, we will furnish bedrooms, a recreation room, and a bathroom. Bedrooms and the recreation room have walls both above and below ground. The bathroom is only below ground. I'm considering what materials are suitable with regard to moisture and other factors.
Bedrooms/Recreation Room - Steel stud/Insulation + OSB/Drywall. I want to insulate the walls that are above ground – the leca blocks have limited insulating capacity.
* Is it okay to use OSB?
* What about an air gap behind the insulation?
* Is it also possible to use wood stud?
Bathroom - Plaster the walls and then tile.
* Do you have to plaster or can tiles be placed directly on the leca?
* What about waterproofing in the basement?
* Is it silly to instead use studs here as well to be able to run hidden electrical and water lines?
The basement walls are plastered externally but haven't been painted yet. When water hits the wall from, for instance, driving rain, it immediately becomes damp through the leca walls. Is this because they haven't been painted yet, or will painting not make a difference?
Regards,
Mattias

Hello. That was a lot about moisture here and there...
Anyway... You have insulated the foundation from the outside, GOOD...
Nothing organic on the inside.... That is OSB.... 2 things you can do with good results, either build a thin wall with leca, and preferably fill with leca in the gap as you do behind....
Then plaster nicely, with, for example, gypsum plaster.... Then you can do whatever you want with the wall, paint, wallpaper, or whatever you want, but nothing ORGANIC....
2. Plaster directly on the interior wall with gypsum plaster.... then read above....
For the bathroom, you can advantageously use steel studs, then the new fiberglass gypsum.... (Don't remember the name) So, if you are studding for electricity, also reinforce for everything you want to mount on the wall, like, a washbasin, cabinets, towel dryer, etc. etc....
Reinforce with steel plate... available in a variety of dimensions.... Then just use self-drilling screws directly into it, without drilling or plugging.....
These were some tips. I'm sure there are others who want to write a few more...
