01.030.0332 Base of Wall | Anchored Brick Veneer, CMU Backing, CMU Foundation This detail illustrates a base of wall condition with a partially grouted and reinforced concrete masonry foundation. Below grade waterproofing and an air/moisture/vapor barrier above grade provide continuous resistance to air and moisture, and continuous insulation offers excellent thermal control. The flexible thru-wall flashing is supported across the cavity with rigid insulation and grout. An optional cavity drainage insert protects the weep vents from becoming obstructed. The detail incorporates a vertical brick expansion joint and a vertical control joint at the block backing. Finish grade is held away from the wall with a gravel mowing strip protecting the masonry against moisture. A system of flashing and weeps at the base allow moisture to exit the drainage cavity. The durable drip edge guards against moisture reentry and may be notched to avoid excessively thick laps.
Expansion joints in the field of tile floors are essential and required in order to accommodate building movements and to prohibit cracks in the substrate from telegraphing to the tile finish. This detail illustrates an expansion joint in tile installed over an unbonded reinforced mortar bed on a concrete floor. A cleavage membrane allows independent movement between the concrete substrate and the tile assembly. The expansion joint goes all the way through the mortar bed. A bond coat of modified cementitious mortar is used to adhere the tile to the cured mortar bed, and a waterproof membrane may be specified over the cured mortar bed. The width, locations, and frequency of field expansion joints are as specified by the design professional. Sealant type shall be specified by design professional and shall be compatible with other components in the system. This detail is based on Tile Council of North America (TCNA) method EJ171C.

This detail illustrates a masonry window head condition with a fixed steel lintel angle anchored to the concrete masonry backing as often used for long-span openings such as ribbon windows. The lintel angle's position may be adjusted vertically via slotted holes and horizontally via shims. The CMU is supported across the opening by a two-course grouted, reinforced masonry lintel integral to the block. A vertical control joint in the CMU is treated with transition membrane which engages with the air/moisture/vapor barrier in the field of the wall providing continuous resistance to air and moisture. Continuous insulation offers excellent thermal control. An optional cavity drainage insert above the lintel protects the weep vents at the bottom of the cavity from becoming obstructed. The steel lintel is protected with thru-wall flashing returning vertically at each end to form an end dam. The durable drip edge guards against moisture reentry and may be notched to avoid excessively thic...
