Types of bond in brick masonry

  1. 1. TYPES OF BOND IN BRICK MASONRY DUTCH BOND:-  Modified form of English bond.  In this bond the corner of the wall are strengthened.  Alternate courses of headers and stretchers are provided as in English bond.  Every stretcher course starts at the quoin with a 3/4 bat.  Every alternate stretcher course, a header is placed next to the 3/4 brick bat provided at the quoin.
  2. 2. RAKING BOND:-  Generally used in thick wall.  In this type of bond, the bonding bricks are kept at an inclination to the direction of the wall. Due to this, the longitudinal stability of thick wall built in English bond is very much increased.  This bond introduced at certain intervals along the height of the wall. FEATURES:-  The bricks are arranged in inclined direction, in the space between the external stretchers of the wall.  The raking of inclination should be in opposite direction in alternate courses of raking bond.
  3. 3.  Raking bond is not provided in the successive courses. It is provided at a regular interval of 4 to 8 courses in the height of a wall.  The raking course is generally provided between the two stretcher courses of the wall having thickness equal to even multiple of ½ bricks, to make the bond more effective.  Raking bonds are of two types 1) Diagonal bond 2) Herring – bone bond.
  4. 4. 1) Diagonal bond:-  In this type of bond bricks are arranged at 45° in such a way that extreme corners of the series remain in contact with the external line of stretchers.
  5. 5.  Brick cut to triangular shapes and of suitable sizes are packed in the small triangular spaces at the ends.  This bond is best suitable for walls which are 2 to 4 bricks thick. The bond is introduced at regular vertical interval, generally at every fifth or seventh course.  In every alternate course of the bond the direction of bricks is reversed. 2) Herring-bone bond:-  This bond is more suitable for walls which are thicker than four bricks thick. Bricks are arranged at 45° in two opposite directions from the centre of the wall thickness.
  6. 6.  The bond is introduced in the wall at regular vertical interval. In every alternate course the direction of bricks are changed.  The bond is also used for ornamental finish to the face work, and also for brick flooring.
  7. 7. GARDEN WALL BOND:-  This type of bond is used for construction of garden walls, boundary walls, compound walls, where the thickness of the wall is one brick and the height does not exceed 2 meters.  This type of bond is not so strong as English bond, but is more attractive.  Garden wall bonds are of three types: 1) Garden wall English bond 2) Garden wall Flemish bond 3) Garden wall Monk bond
  8. 8. 1) Garden wall English bond:-  In this bond, the header course is provided only after 3 to 5 stretchers courses.  In each header course, a queen closer is placed next to the quoin header, to provide necessary lap. In stretcher courses, quoin header are placed in alternate courses.
  9. 9. 2) Garden wall Flemish bond:-  Each course contain one header after 3 to 5 stretchers continuously placed, through out the length of the course.  Each alternate course contains a ¾ brick bat placed next to the quoin header, develop necessary lap, and a header laid over the middle of each central stretcher.  Also known as scotch bond and sussex bond.
  10. 10. 3) Garden wall Monk bond:-  This is special type of garden wall Flemish bond in which each course contains one header after 2 successive stretchers.  Every alternate course contains a quoin header followed by a ¾ brick bat. Due to this, the header rests the joint between two successive stretchers.
