A medical office suite with an area for procedures has resilient sheet goods installed over concrete slab, on grade. The office section has a vinyl plank installed via adhesive with no issues. The procedure section has sheet goods with welded seams. This is an outpatient operation with multiple rooms and open space with beds connected by wide corridors.
Within a few months, the sheet goods developed bubbles in various locations: rooms, open spaces and corridors. Ambient conditions were within a normal service range for this type of space.
