Brick Courses. Everyone has some understanding of brick as a building material. A wide range of building types, from small to large, residential to commercial, old and new, use brick as a primary structural or ornamental material. A brick course is the design the bricks would be laid in rows (or courses) to cover the entire wall. Historically, brick courses played a vital role in the stabilization of a wall, more notably, different brick courses could help support a wall at a window or door opening. Although there are many different types of brick courses, I thought we could touch on a few today.
