Good bricklaying procedure depends on good
workmanship and efficiency. Efficiency involves
doing the work with the fewest possible motions. Each
motion should have a purpose and should achieve a
definite result. After learning the fundamentals, every
Builder should develop methods for achieving
maximum efficiency. The work must be arranged in
such a way that the Builder is continually supplied
with brick and mortar. The scaffolding required must
be planned before the work begins. It must be built in
such away as to cause the least interference with other
Bricks should always be stacked on planks; never
pile them directly on uneven or soft ground. Do not
store bricks on scaffolds or runways. This does not,
however, prohibit placing normal supplies on
scaffolding during actual bricklaying operations.
Except where stacked in sheds, brick piles should
never be more than 7 feet high. When a pile of brick
reaches a height of 4 feet, it must be tapered back 1
inch in every foot of height above the 4-foot level. The
tops of brick piles must be kept level, and the taper
must be maintained during unpiling operations.
The term bond, as used in masonry, has one of the
following three different meanings: structural bond,
mortar bond, or pattern bond.
Structural bond refers to how the individual
masonry units interlock or tie together into a single
structural unit. You can achieve structural bonding of
brick and tile walls in one of the following three ways:
Overlapping (interlocking) the masonry units.
Embedding metal ties in connecting joints.
Using grout to adhere adjacent wythes of
Mortar bond refers to the adhesion of the joint
mortar to the masonry units or to the reinforcing
Pattern bond refers to the pattern formed by the
masonry units and mortar joints on the face of a wall.
The pattern may result from the structural bond, or it
may be purely decorative and unrelated to the
structural bond. Figure 4-4 shows the six basic pattern
bonds in common use today. They are running,
common or American, Flemish, English, stack, and
English cross or Dutch bond.
The running bond is the simplest of the six
patterns, consisting of all stretchers. Because the bond
has no headers, metal ties usually form the structural
bond. The running bond is used largely in cavity wall
construction, brick veneer walls, and facing tile walls
made with extra wide stretcher tile.
The common, or American, bond is a variation of
the running bond, having a course of full-length
headers at regular intervals that provide the structural
bond as well as the pattern. Header courses usually
appear at every fifth, sixth, or seventh course,
depending on the structural bonding requirements. You
