What Does Running Bond Mean In Construction?
The running bond is a widely used pattern in masonry construction, which refers to the sequence and arrangement of concrete masonry units, bricks, stones, or other similar building materials. In this pattern, each course is installed in a running manner, with the joints shifted either 1/3, 1/2, or 1/4 from the adjacent course.
This ensures that the joints never align and are positioned at the 1/3, 1/2, or 1/4 point of both the course above and below. The running bond is a popular choice for constructing the facades of structures and is also used for other hard surfaces, such as ceramic tiles, bluestone, granite tiles, and more.
The success and appearance of the running bond depend on the mason’s ability to maintain consistent and even joint width. If the joint width is not kept uniform the pattern can become unruly and deviate from the intended design.
Benefits Of Running Bond
The running bond is a popular choice among brick masons and builders due to its versatility. This bond doesn’t require the use of header bricks making it possible to use either full-sized or half-sized bricks in the design.
When two walls of thin bricks are built close to each other the structure is usually connected with wall ties and is referred to as a cavity wall bond. The running bond between the bricks in walls that are visible from both sides, such as brick fences or enclosures, provides a strong structure that can easily be adorned with landscaping elements.
The uniformity of the running bond allows for the focus to be on the landscaping and not the brick structure.
However, it is possible to add visual interest to the wall by using an occasional brick of a different color or shade from the majority of the bricks used in the construction. This type of design can be seen in planned communities and some public buildings.
What Are The Different Types Of Running Bond?
There are three major variations of the running bond pattern when it comes to paving. These are the stack bond pattern, the ⅓ running bond pattern, and the half running bond pattern. Each of these variations presents different advantages and visual appeals to homeowners.
The stack bond pattern is the simplest of all the options. In this pattern, the bricks are stacked directly on top of each other as well as side by side, creating a uniform pattern both vertically and horizontally. This eliminates the need for cutting the stones, making it a straightforward process to install.
Additionally, this pattern is the strongest option for withstanding regular foot traffic. However, if homeowners desire a more complex appearance, they can rotate the entire surface 45 degrees for a visually appealing look in their outdoor space.
The ⅓ running bond pattern is similar to the stack bond pattern, with the difference being that the bricks are offset slightly so that each stone overlaps by ⅓ of its length.
This pattern creates a more varied look that is visually interesting, yet still has the strength and simplicity of a running bond pattern. With limited cutting required, this pattern is also a great option for do-it-yourself projects.
The half running bond pattern is often what people envision when they think of a running bond pattern. It is a commonly used and attractive pattern that is considered timeless. In this pattern, the stones are offset so that they overlap by half the width of the brick.
This creates a strong structure, making it an excellent option for creating walls. This pattern is straightforward to install and requires minimal cutting, though it can be rotated 45 degrees for a more complex appearance.
In conclusion, any of these three running bond patterns are simple to install and realistic for a do-it-yourself project. If you are not confident in your landscaping skills, it is also possible to hire a hardscaping expert to lay the pavers in your desired pattern.
Why Is Running Bond Better Than Stack Bond?
Running bond is generally considered to be a better option than stack bond as it creates a stronger structure due to its noncontiguous vertical joints.
Compared to stack bonds, running bonds are beneficial for structural walls since they can hold more weight and create greater stability. Stack bonds are mainly used for decorative walls, but the strength of this type of construction relies heavily on the quality of the mortar used; if the mortar is weak then so is the wall.
Running bonds generally have a higher strength-to-weight ratio overall, making them a better choice when thinking about structural integrity.
