But when adding insulation to an existing slab the vapor barrier is laid over the top of the slab before the foam insulating panels are installed. As the slab will only be able to dry upward the slab should be allowed to dry before finishes are applied.

When slab insulation is provided a sheet polyethylene vapor barrier should be located over the rigid insulation and in direct contact with the concrete slab.
