In A Cement Board, Cement And Reinforcing Fibers Are Combined To Form Sheets Of Varying Thickness
Cement Board

The most typical sub-flooring material for tile backsplashes, countertops, floors, and walls is Cement Board. Its function is to support the tile, which must rest on a level surface to remain intact. Because of this, this product is also known as cement backer board or backer board. In building supply stores, cement board is typically located close to the drywall. Even though it costs a little more than drywall, it's a wise investment because you won't have to repair any damaged tiles. The boards, which cost about $10 per sheet and come in 3 x 5 foot sheets, are great for shower stalls and bathtub surrounds.

In order to boost strength, the boards are constructed of cement, water, silica, limestone flour, and fibreglass. Cement Board doesn't contain any organic components or "food," making it more resistant to mould, rot, and decomposition than wood or drywall (paper faced). Despite not being waterproof, the core can get wet without disintegrating (what happens with wet drywall). When used in moist environments like bathrooms, it's typical to brush a waterproofing membrane over top of the board because it's still crucial to try to keep these boards, and the objects behind/under it, dry (showers, bathtub surrounds and floors).
