I am looking to build (extend) a wall out about 3 feet or so into the garage from an existing laundry room. Just want to have some additional working space in the laundry area.
My concern is, the framed floor would be over the existing concrete floor of the garage. Footing - sill - floor joist etc.
I know this scenario will lead to moisture issues with the concrete floor. I wondered if a 6 mil vapor barrier and/or drylock would be a solution.
This area would also be "unaccessible" when completed. There would be no utilities involved, just the extra square footage is all I'm after.
Would the fact that it is unaccessible be an issue if there is no reason to access it? No plumbing, electrical, HVAC etc.
The moisture issues from a concrete floor beneath a typical wood framed floor is my concern.
