what is standard horizontal course of brick

A course is a horizontal layer of bricks or stones. It is the surface of stone perpendicular to the line of pressure. It indicates the lower surface of bricks or stones in each course. The inner surface of a wall which is not exposed is called the back. The material forming the back is known as backing.

Understanding Brick Size Nomenclature

There are three different ways of discussing sizes when it comes to brick and it is important to understand the different sizes so there isn't any confusion - we will start by discussing the different dimensions: specified, actual, and nominal.

Brick Selection for Architects

Architects are mostly interested in the aesthetic appearance of the brick wall, but when it comes to detailing it is important to understand the sizes of bricks. That said, most architects will select bricks based on their color and bond pattern. The size of the brick is tied to the bond pattern and manufacturer specifics.

A Word About Mortar Joint Sizes

The predominant mortar joint width used in construction is 3/8". In fact, the International Building Codes reference TMS 602 Specification for Masonry Structures, which defaults to a 3/8" mortar joint so this should be the main starting point for architects and engineers, but always confirm the specified size of your selected brick.

Calculating Brick Openings

When calculating brick openings, you count the courses (vertical) or brick lengths (horizontal) to get the Masonry Opening (M.O.). However, to get the actual opening you have to factor in the additional mortar joint that is missing from the standard nominal dimensions.

Brick Orientation

The diagrams below represent the orientations for bricks as they are laid in walls. The red face is the face that is exposed. Different orientations are combined to create brick bonds.

Brick Types and Specification Based on Application

Architects generally select bricks based on the type of application. Many factors go into the selection, including durability ( see Grades below ), load capacity, and appearance. The following table covers the major types of brick, their ASTM specification criteria, and the general usage applications.

Brick Grades

Brick grades indicate the durability of a brick when it is exposed to moisture and freezing. There are three factors that help determine brick durability: compressive strength, water absorption, and the saturation coefficient.

What is the governing factor for deciding the dimensions or size of the bricks?

The bricks are prepared in various sizes, the governing factor for deciding the dimensions or size of the bricks is the locality. Bricks that are not standardized are known as traditional bricks and along with the thickness of the mortar, it is known as the nominal size of the brick.

What is a joint in a course?

Joint. It is the junction of two or more bricks or stones. If the joint is parallel to the bed of bricks or stones in a course then it is termed as bed joint. The joint which are perpendicular to the bed joints are termed as vertical joints or side joints or simply joints.

If the joint is perpendicular, then the bed joints are termed vertical joints, side joints, head joints, ...

What is a stretcher course?

Why are beaded joints not recommended for exterior use?

These beaded joints create interesting shadows, but they are not recommended for exterior use because of their exposed ledges and the erosion over time leaves the joint weakened and untidy.

Running Bond

The running bond is the most used bond and is composed of stretchers offset by 1/2 brick per course. It is often used in cavity wall construction reinforced with metal ties back to the main structural wall.

Common or American Bond

A common bond, also referred to as the American bond, has a course of headers inserted every five or six courses. A header is always centered on a stretcher and the joints of each course of headers always align.

English Bond

The English bond is built with alternating courses of stretchers and headers where a header is centered above a stretcher. The joints of the stretcher courses align and the joints of the header courses align.

Flemish Bond

For the Flemish bond, each course is made up of alternating stretchers and headers. Each header is centered on a stretcher above and below.

Stack Bond

The stack bond is made up of courses of stretchers where each stretcher is stacked directly above a stretcher and the joints align. This is not a structural bond and is generally used on interiors for non-load bearing walls.
