Masonry Bond Patterns


 Running or all stretcher bond: the running bond consists entirely of full bricks known as stretchers.  In trade terms, a stretcher is a brick laid with its long side facing out.  A running bond is achieved by laying all stretchers centered over the stretchers of the course below (Kreh 154 –155).

"Running Bond"


Common or American Bond: similar to the running bond, but instead have a course of headers (short –side or brick) inserted at regular intervals to tie the masonry units together.  Headers are usually inserted starting with the fifth, six, or seventh row.  The odd numbered row is more commonly known as the nth row.  The common bond is typically used when constructing a solid masonry wall (Kreh 154 –155).


"Common or American Bond"





Flemish Bond: this pattern is constructed by laying alternating stretchers and headers on the same course, with each header centered over the stretcher of the course below.  On every other course, the headers will be found form an even, vertical line.  The Flemish bond is only to be constructed with solid brick, therefore, this bond is less cost efficient than other bonds.  On the other hand, the Flemish bond is very aesthetically pleasing (Kreh 155).


"Flemish Bond"


English Bond: unlike the Flemish bond, the English bond is constructed with alternating courses of headers and stretchers.  The headers are centered on the stretchers and the joints between the stretchers in all courses are in line vertically (Kreh 156).  This bond is commonly used when a structure with an 8” solid brick wall is being assembled.  The headers must be cut when a 4” wall is to be constructed.  Although not commonly used today, the English bond is preferred when creating colonial reproductions (Kreh 156).


"English Bond"



Garden Wall Bond: the garden wall bond is a derivative of the Flemish bond, and typically used when enclosing a garden, courtyard, or estate (Kreh 157).  One variation of this bond is created with two stretchers and a header alternating on the same course (double stretcher garden wall bond).  Another method is the three stretcher garden wall bond, and it consists of three stretchers and a header alternating on the same course (Kreh 158).  The alternating courses create a diamond effect which is magnified in the three stretcher form (Kreh 158).

"English Garden Wall Bond"



Stack Bond: generally used for decorative purposes.  In the stack bond, courses of stretchers are laid directly over each other (Kreh 157).  The stack bond is not an efficient pattern for load bearing masonry.

Bond Meanings
 Mortar Bond: the mortar bond is the adhesion of the masonry unit with the mortar

Structural Bond: the structural bond is the interlocking of the masonry units for the purpose of weight distribution

Pattern Bond: the pattern bond is the arrangement of masonry units to form patterns, texture, or designs (Kreh 143).








Brick Positions

Stretcher: brick laid in a horizontal position with the longest, narrowest side exposed at the front of the wall.  This is the most common brick position (Kreh 147).


 
Stretcher

 Header: brick laid with the 4” face of the brick exposed at the front of the wall.  The widest part of the header is laid in the mortar bed.  Headers are used for tying two separate walls together, capping walls, and contributing to different patterns (Kreh 147).

 
Header

 Soldier: brick laid in a vertical position on its narrowest and shortest side, with the longest side of the brick exposed on the front side of the brick exposed on the front side of the wall.  Solider bricks are most commonly used over doorways, windows, or openings to simulate an arch (Kreh 147).

Soldier

 Shiner: brick laid with the widest side of the brick in a horizontal position exposed on the front of a finished wall.  The shiner is also used for leveling, paving, and decorative purposes (Kreh 147).

 
Shiner

 Rowlock: brick laid in a vertical position with the end of the brick facing the front of the finished wall.  The fact that the shiner is laid on its narrowest side distinguishes it from a header.  Rowlocks are used to cap walls and decorative patterns (Kreh 147).

 
Rowlock

 Sailor: brick laid with the widest part of the brick facing the front of the finished wall in a vertical position.  Sailor bricks are most commonly used to form different bond patterns (Kreh 147).

Common Brick Joints

Concave: severe weather resistant joint that is tooled
V –Shape: severe weather resistant joint that is tooled
Flush: poor weather resistant joint that is troweled
Raked: poor weather resistant joint that is troweled
 Extruded: poor weather resistant joint that is troweled
Beaded: moderate weather resistant joint that is troweled
 Struck: moderate weather resistant joint that is troweled
 Weathered: severe weather resistant joint that is troweled

(Chart Data Comes From Figure 8.11 in Allen p. 254)

            The Brick Institute of America is chiefly responsible for establishing the dimensions of bricks used for construction in North America.  Modular bricks are manufactured so that three courses plus 3/8” mortar joints add up to a vertical dimension of 8”.  The length of one modular brick plus the mortar joint tallies to a horizontal dimension of 8”.  As illustrated by the chart, the alternative brick dimensions are calculated for 3/8 –inch and 1/2 –inch mortar joint thickness (Allen 254).
