Details 01.030.0321 and 01.030.0321.2D (Brick Ledge – Top of Foundation Above Grade):
Foundations with a veneer shelf that is lower than the top of foundation and floor level can prevent moisture that might penetrate the flashing system from entering the building. They are also used when finished grades vary. A drip edge may be omitted at the designer’s discretion if the finished grade is kept 4” to 6” below the masonry veneer.
