Running Bond - the simplest pattern
Common Bond - similar to running bond but a head course at every 5th, 6th, or 7th course
Stack Bond - no overlapping units, longitudinal reinforcement
Flemish Bond - each course consists of alternating headers and stretchers
Common Bond - every 6th course is composed of Flemish headers
English Bond - Pattern consists of alternating stretcher and header courses
