Copyright Goodheart-Willcox Co., Inc. Chapter 14 Wall Systems 285 Brick Veneer Foundations Brick veneer on a frame backing transfers the weight of the veneer to the foundation. Typical foundation details for brick veneer are shown in Figure 14-14. The foundation brick ledge supporting the brick veneer should be at least equal to the total thickness of the brick veneer wall assembly. Foundations must extend beneath the frost line. Check with your local building official to determine the required depth of the footing as required by local code. Foundation design considerations include differential settlement and the effect of concentrated loads, such as those from columns or fireplaces. Brick walls that enclose crawl spaces must have openings to provide adequate ventilation. Openings should be located to achieve cross ventilation. Masonry Wall Applications Several ties used with wood framing are shown in Figure 14-15. Ties, as well as nails, are to be made of a noncorrosive material. There should be one tie for every 2 2/3 sq ft of wall area with a maximum spacing of 24″ O.C. in either direction. The nail attaching a corrugated tie must be located within 5/8″ of the bend in the tie. The best location for the nail is at the bend in the corrugated tie. The bend should be 90°.
