Lesson 11 : Bonds In Brick Work

Flemish Bond

In Flemish bond, each course is comprised of alternate headers and stretchers. Every alternate course starts with a header at the corner (i.e. quoin header). Quoin closers are placed next to the quoin header in alternate courses to develop the face lap. Every header is centrally supported over the stretcher below it. Flemish bonds are of two types:

  1. Double Flemish bond

    In the double Flemish bond, each course presents the same appearance both in the front face as well as in the gback face. Alternate headers and stretchers are laid in each course. Because of this, double Flemish bond presents better appearance than English Bond.

    Special features of double by Flemish bond are

    • Every course consists of headers and stretchers placed alternately.
    • The facing and backing of the wall, in each course, have the same appearance.
    • Quoin closers are used next to quoin headers in every alternate course.
    • In walls having thickness equal to odd multiple of half bricks, half bats and three-quarter bats are amply used.
    • For walls having thickness equal to even multiple of half bricks, no bats are required.
    • A header or stretcher will come out as header or stretcher on the same course in front as well as back faces.

  2. Single Flemish Bond

    Single Flemish bond is comprised of double Flemish bond facing and English bond backing and hearting in each course. This bond thus uses the strength of the English bond and appearance of Flemish bond. However, this bond can be used for those walls having thickness at least equal to 1 ½ brick. Double Flemish bond facing is done with good quality expensive bricks. However, cheaper bricks can be used for backing and hearting.
