When laying bricks, the manner in which the bricks overlap is called the bond.

  1. Stretcher bond (also known as running bond) is the most common bond. Ref Fig 6.4 (a) It is easy to lay. It is entirely composed of stretcher bricks, set in rows that are offset by half a brick as shown in the figure. Stretcher bond is generally used to build a single-brick wall.
  2. This produces a solid wall that is a full brick in depth.This is fairly easy to lay and is the strongest bond for a one-brick-thick wall.
  3. Header bond (also known as Spanish bond) was a very common bond for bearing walls Ref fig 6.4(c).
  4. Flemish bond-Flemish bond, also known as Dutch bond, has historically always been considered the most decorative bond. Ref Fig 6.4(d)
  5. Rat-trap bond, also known as Chinese bond.

The air cavity gets created between the bricks hence the name ‘Rat – trap bond’. It shown in fig 6.4(e). It requires less number of bricks than a solid wall. Air cavity helps in keeping the building cool.
