What kind of flooring uses a cement board underlayment?


Answer by  dcnelson28 (38)

Cement board underlayment is common in bathroom areas, pre-fabricated shower surrounds, ceramic tile floors, basements, and areas that are subject to water damage, where grout is used, or to protect the upper level from dampness in a lower level. The thickness of the cement board underlayment depends on the specific needs of the job.

Cement board underlayment is used to provide rigidity between a wooden sub-floor and a finished tile floor. The wooden sub-floor may be an old tongue-and-groove oak or pine floor. The desired end result is to prevent tile and grout joints from splitting or cracking when being walked across or moving furniture around over the life of the finished floor.
