Stretcher bond is a brick wall format with a repeating pattern of vertical supports bonded to the foundation. It is only applicable in thin-walled rooms and requires ties to the foundation and roof system to prevent collapse. It is easy to build and often used in commercial interiors to create a cavity wall. The top three layers are usually filled with concrete for structural integrity.
In the field of masonry, the term stretcher bond is a reference to the format and standard to which some types of brick walls are built to be stable. Stretcher bond is the term given to the repeating pattern in which the bricks are laid. This model includes vertical supports bonded to the foundation of the structure on which the wall is being built.
This type of brick format is mainly used indoors because it is only applicable in thin-walled rooms. In fact, stretcher bonding wall is only usable in thinner brick wall settings. This is because it is only half as thick as a brick.
The reason the stretcher connecting wall is required to have vertical supports bonded directly to the supports or foundation for the structure on which the wall is being built is because the thickness of the wall does not allow the wall to stand on its own. Without ties to the foundation and roof system, the stretcher link system layout would fail, especially if the wall has significant height. This could end up in the lower layers of the wall bending under the weight of the brick and causing the wall to collapse.
Stretcher bonded wall systems are often considered the easiest to build due to their simplistic pattern approach. Masonry to the full thickness of the wall is not required. The bricks are laid with mortar joints between them, and stacked alternately on each layer.
The bricks are laid starting from the ground or foundation and working upwards until the desired height is reached. The wall structure is bonded both to the foundation and to itself, with vertical support ties running the full height of the wall. Horizontal ties are placed between wall layers running from each wall to the opposite wall.
This specific type of brick pattern and wall system is very common and often used to create a cavity wall or wall system that creates a cavity inside it. These walls are very popular in commercial interiors, mainly for decoration or to divide the space. They are usually three or four sided and give the impression of a solid structure, although in most cases they are hollow from the third layer up. The top three layers are usually filled with concrete to provide structural integrity.
