Vinyl plank flooring over concrete in a basement
I am doing the design to upgrade the basement of a house in Leadore, Idaho, 83464. A vinyl plank floor has been requested, to minimize the loss of headroom.
I’ve never worked with the vinyl plank before, and have some hesitancy about specifying it directly over the concrete. The building is built on an extremely well drained alluvial gravel, and the landscaping drains away from the building, so I don’t expect any issues with water penetration, but I am concerned with the moisture wicking in from the slab, and condensation from the air.
Is the vinyl plank going to breath enough through the seams that I don’t need to worry about transfer through the concrete, or should I be considering some form of water/vapor proof barrier system that will elevate the vinyl enough to allow evaporation?
