Photo of moisture on concrete floor in slide show
what’s the origin of the moisture in the concrete floor and mold behind the trim photo? Was it when the floor was cleaned? Or a plumbing break? Or when the concrete was drying during install?

This slide was an example of wicking--moisture moving by capillary action up through the concrete and wood and into the gypsum board (all porous). The floor is not "wet"--it looks "dry" but without a capillary break between these materials, moisture continually migrates from the concrete. It is likely that there is no capillary break between the soil and the concrete, so there is a continual source of moisture.
