Expansion Joints. Expansion joint materials for horizontal and vertical movement may be required in brick veneer when there are long walls, wall returns, or shelf angles. Expansion joint materials and placement should be in accordance with the information given in Technical Notes 18 Series.
Horizontal Joint Reinforcement. Horizontal joint reinforcement should be fabricated from wire meeting ASTM A 82 or ASTM A 185. It should have a corrosion-resistant coating which complies with ASTM A 116, Class 3, or ASTM A 153, Class B-2.
Lintel Materials
Reinforcement for reinforced brick masonry lintels should be steel bars manufactured from steel in accordance with ASTM A 615, Grades 40 or 60, and should be at least No. 2 bar size. Steel for lintels should conform to ASTM A 36. Steel angle lintels should be at least 14 in. (6 mm) thick with a horizontal leg of at least 3½ in. (90 mm) for use with nominal 4-in. (100 mm) thick brick veneer, and 21/2 in. (60 mm) for use with nominal 3-in. (75 mm) thick brick veneer. The maximum clear span for 4-in. (6 mm) thick steel angles is 8 ft (2.44 m). The minimum required bearing length is 4 in. (100 mm). The maximum clear span may be restricted by the fire protection requirements of some building codes. Lintel design information may be found in Technical Notes 17H and 31B.
Caulking and Sealants
There are numerous types of caulking and sealants available that are suitable for use with brick veneer. The material selected should be flexible and durable. The superior sealants have a higher initial cost, but their flexibility and durability result in savings of maintenance costs due to the reduced frequency of recaulking. Good grades of polysulfide, butyl, or silicone rubber sealants are recommended. Oil-based caulking compounds are not recommended since most lack the desired flexibility and durability.

Foundations for Brick Veneer
Figure 4 shows three typical foundation details for brick veneer. It is recommended that the foundation or foundation wall supporting the brick veneer be at least equal to the total thickness of the brick veneer wall assembly. Many building codes permit a nominal 8-in. (200 mm) foundation wall under single-family dwellings constructed of brick veneer, provided the top of the foundation wall is corbeled as shown in Fig. 4C. The total projection of the corbel should not exceed 2 in. (50 mm) with individual corbels projecting not
