Stacked bond

What is Stacked bond?

Definition of Stacked bond in Construction

In masonry construction, an installation pattern that stacks the masonry units one on the top of another. This type of masonry construction will align the mortar joints, so that they too, line up, one over the other. Stacked bond is not as popular as the running bond or some of the other bonding patterns used. This type of masonry pattern is not as strong as other patterns, due to the alignment of the joints. which allows any cracking, to simply follow the joint pattern, and propagate through the structure. Stacked bond is normally used in situations that are architecturally designed, and the look is essential to the overall appearance. Stacked bond is not recommended for any type of structural use due to the reasons already stated, however, the same fire rating is established with a stacked bond as with all the other types of masonry bonds. The stacked bond requires an experienced mason. The reason for the difficulty is that most normal masonry units are not manufactured to exact size and consistent dimensions. The differing sizes and shapes of masonry units, requires that the mason realize this situation, and cull out the masonry units of similar shape and size. In addition, the accuracy of the installation must take into account the randomness of the masonry units and the mason must judge the layout and alignment of the units, to look as straight and accurate as possible. A mason must understand the limitations or this type of bonding and must adjust accordingly.
