A brick ledger is not defined in the provided reference. Based on common construction terminology, we can understand its components to infer the meaning. Brick ledgers are structural elements and are not the same as brick ledge flashing. A brick ledger, in general construction terms, refers to an angle iron, steel plate, or other structural support attached to a foundation wall or structural frame to provide support for a brick veneer or other masonry cladding.
Here's a more detailed breakdown:
-
Purpose: The primary purpose of a brick ledger is to create a shelf or ledge that can support the weight of the brick veneer or other masonry material. This is especially important when the brick veneer doesn't start directly at the foundation level.
-
Materials: Brick ledgers are commonly made from:
- Steel: Steel angle iron or steel plates are frequently used due to their high strength and ability to withstand significant loads.
- Concrete: In some cases, a concrete ledge may be poured as part of the foundation wall.
- Wood: While less common for heavy brick veneer, wood can be used for lighter masonry or decorative elements.
-
Installation: The method of installation depends on the material of both the brick ledger and the supporting structure. Common methods include:
- Bolting: Steel ledgers are often bolted directly to the foundation wall or structural frame.
- Welding: In steel frame construction, the ledger may be welded to the frame.
- Casting in Place: Concrete ledgers are typically cast as part of the foundation.
-
Importance: Brick ledgers are crucial for structural integrity. Without proper support, the brick veneer could crack, bulge, or even collapse.
Distinction from Brick Ledge Flashing:
It is important not to confuse a brick ledger (a structural support) with brick ledge flashing. Brick ledge flashing is a water-resistant or waterproof material installed at the junction between the foundation and the brick veneer to prevent water infiltration. While both are important components in brick veneer construction, they serve different purposes. Brick ledge flashing protects against water damage at the joint where the concrete ledge of the foundation meets the wood framing and prevents the brick or masonry siding from directly touching the concrete foundation.
