This session is intended to provide insights into determining the origin and cause of wood floor failures associated with a concrete slab installation. Water vapor commonly migrates through concrete slabs due to the difference in vapor pressure between the soils beneath the slab and the conditioned interior of a structure. The migration of moisture through the concrete slab necessitates the need for a vapor retarder between the flooring and the concrete slab. The majority of wood floor failures on a concrete slab are related to deficiencies associated with the installation of the vapor retarder. Case studies will be used to demonstrate a variety of damaged floor installations and the underlying conditions leading to the damage.
