When and why should a waterproofing membrane be used in conjunction with a stone installation? What are some of the specific areas that make sense to use a waterproofing membrane? Some of the obvious use areas are showers, spas, steam rooms, fountains and pools. These are generally considered “constant wet areas” and by building code and design specification, a waterproofing membrane must be used to protect spaces below and adjacent to the stone installation. The Tile Council of North America’s Handbook for Ceramic Tile Installations provides many details that depict the use of a waterproofing membrane in an array of installation methods, including walls, floors, decks, tubs, showers and pools.
