Perimeter expansion joints in tile are essential and required in order to accommodate building movements. This detail illustrates the use of a prefabricated expansion joint profile strip at the floor-wall interface. The perforated horizontal and vertical anchoring legs of the profile strip are fully embedded with a cementitious bond coat of adhesive mortar, anchoring the profile strip to the floor and wall substrate. The movement zone should be free and clear of mortar, allowing the gasket to expand as the tile expands. Bond breaker tape (not shown in the detail) may be used to keep the movement zone below the gasket free of mortar. The width, locations, and frequency of field expansion joints are as specified by the design professional.
