Hello

I'm sitting here pondering.
We should drain first in 2012, but now I'm going to build a staircase down to the basement.
Can I straighten up the wall with steel studs and then put up OSB which I ventilate well and then gypsum. I want the OSB to have a stable wall to attach the staircase to.
If I ventilate the wall well, do you think there could be problems?

When we moved in, there was wallpaper directly on the leca and there was no mold, so it seems like it's a dry wall anyway. We have very moraine soil and according to old plans, the wall should be protected with cold asphalt.

Hoping for opinions! :)

Best regards, Jan
 
Do you mean attaching the staircase to the OSB board?
Sounds okay but will probably work.
Why not a stud?
 
I would have liked to use wooden beams, but from what I've heard, you're not supposed to have them in basement walls?
The staircase should also "stand" on the floor.
 
No idea and not going to answer you on something I don't know anything about :)
 
Difficult when you don't see/know what it looks like?
But a staircase doesn't need to be attached to a wall, build a staircase that supports itself like a ladder does and place it on the floor, attach it to the upper floor.
Wood should be avoided where it is damp, but if you don't enclose it and only attach a beam to the wall, you'll see if any moisture-related problem arises. But an open beam where you place some type of tar paper between the beam and the wall during installation shouldn't suffer moisture damage.
 
Seems a bit like people generally believe that basements are dripping with moisture like an aquarium or something :)
Tap a rule against the wall, that's been done for 100 years.
It works but don't cover it with plastic afterwards.
 
it feels like I shouldn't be too worried, as long as I don't let the air in the wall stand still.
gonna start sketching a bit now =)
