TCNA Method F112 - Bonded Mortar Bed Over Concrete Substrate

This detail shows ceramic or stone tile on a bonded mortar bed over a concrete substrate. The mortar setting bed is bonded to the concrete with a cementitious bond coat. The tile may be fresh-set (i.e. the mortar bed is still workable) and adhered to the mortar with a cementitious bond coat, or the mortar bed may be allowed to cure before adhering the tile. If specified, a compatible waterproof membrane may be applied over the mortar bed if it is cured. Expansion joints in the floor assembly must be provided at locations shown by the design professional. This detail is based on the Tile Council of North America (TCNA) Handbook method F112.
