Cementitious Backing Boards
Use this 3-part specification template to specify a cementitious backing board for use behind and under tile flooring.
Most building codes require this type of board to be installed in showers and other wet locations where long-term exposure to moisture may occur.
Boards are used on walls and ceilings to support the tile, so it doesn’t crack or fall off. There are many types of backing boards, however, cementitious boards are the most common.
Boards are made of cement and other materials that provide a smooth surface for the tile to adhere to. They’re also available in different thicknesses, so you can choose one that best fits your needs.
