Abstract:
This month’s Q&A discusses moisture vapor protection for concrete slabs that will be covered with moisture sensitive flooring materials. It focuses on the water vapor movement through a concrete slab, potential ways of reducing the water vapor transmission rate, and means of selecting a viable moisture vapor mitigation option.
