English bond brick laying pattern
The traditional English brick bond alternates between stretcher and header courses, with headers centred over the stretchers underneath. This is the oldest pattern, and was commonly used until the end of the 17th century. English Bond is considered stronger than Flemish bond, so continues to be used for civil engineering projects, such as bridges, viaducts and embankments.
