Definition

A brick ledge is a recessed or projecting horizontal surface formed in a foundation wall, stem wall, or slab edge to support the weight of exterior brick veneer or similar masonry.

Explanation

In residential construction, a brick ledge is commonly formed as part of the concrete foundation or masonry foundation wall. It creates a lower bearing surface outside the primary wall framing so the brick veneer can be supported independently of the wood-framed wall.

The brick veneer rests on the ledge while an air space typically separates the masonry from the framed wall behind it. The ledge must be positioned so the masonry is adequately supported while allowing the wall assembly, flashing, drainage provisions, and weep openings to function as intended.

A brick ledge is different from a shelf angle, which is typically a steel angle attached to the structure to support masonry at an elevated location.

Why It Matters

The brick ledge carries the vertical load of the masonry veneer. Inadequate bearing, displacement, deterioration, or improper positioning can contribute to cracking, movement, or loss of support at the brick veneer.

Example Usage

I observed that the brick veneer is supported by the foundation brick ledge along the exterior wall.
