What are the course in bonding?
Bonding may be achieved by overlapping alternate courses (rows or layers) in brickwork, by using metal ties, and by inserting units vertically so they join adjacent courses. A bond course of headers (units laid with their ends toward the face of the wall) can be used to bond exterior masonry to backing masonry.

Which Bond is best for brick work?
The header Bond in brick is considered to be the strongest and widely used bond in masonry construction. Header means a shorter square span face of the brick which has dimensions 9cm x 9cm. The arrangement is such that it forms the strongest bonding between bricks, making it the strongest bond for bricks.
What are brick courses?
A course is a layer of the same unit running horizontally in a wall.
