2.SINGLE FLEMISH BOND

The bond provided in a wall with Flemish bond facing and English bond in backing is called Single Flemish bond.

ADVANTAGES AND DISADVANTAGES OF SINGLE FLEMISH BOND

• It provides better appearance.
• It can be made more economical by using cheap quality of bricks on the back of the wall.
• It weakens the overall strength of the wall because of maximum use of brick bats and existence of continuous vertical joints.
• It cannot be provide in walls having thickness less than one and half brick.

Suitability: Single Flemish bond is used where first class bricks are specified for facing in order to provide good appearance to the facing of wall. 

3.HEADER BOND

• Header bond is created by rows of headers, only displaced by half a brick on each row. This bond is often use to create curved brickwork.
• A brick course laid flat with the short end of the brick exposed.
• This method is particularly strong as the width of the wall is the whole length of a brick.
• Historically it was used for buildings of high quality, often used for curved brickwork.

4.STRETCHER BOND

Stretcher bond is one of the most common bonds. It is easy to lay with little waste and composed entirely of stretchers set in rows, offset by half a brick.

Originally used for single brick walls, it became the obvious choice for cavity walls with the least amount of cutting required.

It is therefore the most economical bond pattern and is extensively used in modern building
