06.130.1302: Floor Tile Expansion Joint - Over Concrete Control Joint
This detail shows a tile expansion joint in floor system made up of tile adhered to a concrete subfloor using a dry-set or latex-modified portland cement mortar bond coat. A 1/4″ wide saw cut is made at the existing crack in the concrete to form a control joint, and a tile expansion joint is placed directly above that concrete control joint.
