English bond
This is a pattern formed by laying alternate courses of stretchers and headers. The joins between the stretchers are centred on the headers in the course below. This is one of the strongest bonds but requires more facing bricks than other bonds.
Flemish bond
This is formed by laying headers and stretchers alternately in each course. The headers of each course are centered on the stretchers of the course below. This bond is strong and often used for walls that are two bricks thick.
The Flemish bond can be sub-divided into two different categories.
1. Single Flemish bond and
2. Double Flemish bond.
Difference between English Bond and Flemish Bond
1- English bond is much stronger than a Flemish bond for the walls thicker more than 1½ brick.
2- Flemish bond shows the more attractive and pleasing appearance of masonry work.
3- Flemish bond is economical as it uses broken brickbats, although it requires some extra mortar for additional joints.
4- Uses of the flemish bond are a bit more difficult than an English bond. Flemish bond requires more skilled labor and supervision
