Subfloor over a concrete slab with wall-to-wall carpet
Hi I am chris, located in southern IL.
I have read a few posts about installing a sub floor on a concrete slab. I have no clue if this was built with crushed gravel and foam before it was poured, lets assume its just old school poured nothing fancy.
This is a “workshop”, Think garage no garage door (16’x24′).
I want to make this live able space, With wall to wall carpeting.
It seems the wall to wall carpeting is just bad in slab setup.
I read about 3 options: dricore, foam board + plywood + tap-cons, Sleepers. Seems non accomplish my goal to make it a live able space with wall to wall carpet.
I was thinking lay a water / vapor barrier Then frame a sub floor out of 2×10 (like craw space but sitting on the slab/ vapor barrier, no block or piers), but I could not find info on spacing and how to frame it. Was reading about it might need vented like craw spaces. Then read about plastic/barriers on the slab is just inviting of mold. If I new a name for this method I could find books on it. (that is if it is a method.)
I can do the wall and ceiling, I just need to get this slab / sub floor issue sorted.
Thoughts and ideas?
Please and thanks
