Bricks in home construction are typically organized in courses and held together by mortar to form walls, which can be load-bearing or veneer.
Here's a breakdown of how bricks are organized in building a home:
-
Courses: Bricks are laid in horizontal rows called courses. The consistent layering of these courses creates the wall's height and strength.
-
Mortar: Mortar acts as the binding agent, holding the bricks together. It fills the spaces between the bricks, distributing the load and preventing water from penetrating the wall.
-
Brickwork Types:
- Brick Veneer: In many modern homes, bricks form an outer layer (veneer) for aesthetic purposes. Behind the brick veneer is a structural frame, typically made of wood or steel, which provides the actual support for the building. The brick veneer is attached to the frame with brick ties. This is a non-structural application.
- Load-Bearing Brickwork: In older construction, bricks can be the primary structural element of the home. The walls themselves bear the weight of the roof and upper floors. This requires careful planning and execution to ensure stability.
-
Bonding Patterns: The specific arrangement of bricks within a course, and in relation to adjacent courses, is called the bonding pattern. Different patterns, such as running bond, English bond, and Flemish bond, affect the wall's strength and appearance. The most common is running bond where each brick is offset by half a brick length from the course below.
-
Brick Ties: In brick veneer construction, metal brick ties are crucial. They attach the brick veneer to the structural frame, ensuring that the brick stays securely in place, resisting wind loads and other forces.
-
Weep Holes: These small openings are typically located at the base of brick veneer walls. They allow any moisture that penetrates the brick to escape, preventing water damage and promoting ventilation.
