Brick Bonding

Brick Bonding

Definition : The arrangement of bricks overlapping overlappin g between courses in order to distribute load and provide stability. Bondig can also be used for decorative purposes as it creates patterns.

3 Main Purposes To Brick Bonding i. ii. iii.

To obtain maximum strenght during load distribution To resist lateral or overturning forces To create an acceptable appearance

Types of Brick Bonding



Stretcher bond

Consists of all strechers in every course and is used for half-brick walls and the half-brick skins of hollow or cavity walls.



Header bond

It only use the header (end) of the bricks as the facing wall. This bonding is particularly strong as the width of the wall is the whole length of a brick.



English bond

A very strong bond consisting of alternate courses of headers and stretchers.



Flemish bond

It is created by alternately laying headers and stretchers in a single course. The next course is laid so that a header lies in the middle of the stretchers course. It is sometimes referred as double Flemish bond.



English Garden Wall bond

Consists of three courses of stretchers to one course of headers.



Herringbone bond

It is a type of brick laying in which the rows of headers are laid at right angles to each other to form a series of zigzags.

It is used to build one-and-a-half brick walls that can be reinforced vertically with steel bars for added strenght. It is suitable for retaining walls.



Stack bond

A pattern made up of rows of stretchers with each strecher centred on the stretcher below it. The bricks run vertically down the entire wall. This type of bond is not very strong, it is used for decorative purposes only.

Rules of Bonding These rules should be observed in order to ensure good bond with 9 x 4 ½  x 3 bricks. i.

The bricks must be uniform in size and the arrangement of the bricks should be uniform throughout the wall.

ii.

Bat should be used as little as possible.

iii.

The bricks in the interior of the walls should be laid as headers that is across the wall.

iv.

The lap should be below 2 ¼ inch along the lenght of the wall and 4 ½ inch across the thickness of the wall

v.

The vertical joints in every course should be vertically over another whether on the face or in the interior of a wall.
