types of brickwork bonding

3. english bond
  • A very strong bond consisting of alternate courses of header and strecthers with a header face lying directly over the centre of a strecther face below
  • English bond avoids the repetition of header faces in each course
  • THe colour of header faces may differ from the colour of strecther faces
  • In english bond , this difference of colour is shown in succesice horizontal courses
4.FLemish bond
  • This bond is sometimes reffered to as double-flemish bond
  • Each course consists of alternate headers and strecthers
  • THe bond is laid in which header faces lie directly above and below a strecther face .
  • This bond requires fewer facing bricks than english bond
  • This bond is generaly considered the most attractive bond for facing brickwork because of the variety of shades of colour between header and strecther faces dispersed over the whole face of the building
  • ITs appearance is considered to be better than english bond , but it is not quite so strong
