Is a vapor barrier necessary under a concrete slab?
A concrete vapor barrier is any material that prevents moisture from entering a concrete slab. Vapor barriers are used because while fresh concrete is poured wet, it’s not supposed to stay that way. It needs to dry and then stay dry to avoid flooring problems. This is why a vapor barrier under concrete is essential.
Should I insulate under my basement slab?
Heat is also lost through the basement floor. Creating an insulation layer and a vapor barrier between the concrete slab and the ground beneath it is the best practice in insulating basement floors. The insulation barrier will help keep warm air in, and the vapor barrier will keep unwanted moisture out.
Is a vapor barrier required under a concrete slab?
Water vapor will always move from a high relative humidity environment below the building into an area of low relative humidity – even through concrete.
