A blocking course is a construction element that is used to provide a transition between two different heights in a wall. It is typically made up of a row of masonry units, such as bricks, stones, concrete blocks, or precast concrete planks, that are laid in a similar way to a regular masonry course. However, the individual masonry units are cut to different heights to create a gradual transition between the two heights of the wall. The purpose of the blocking course is to provide structural support to the wall while also creating an aesthetically pleasing transition. Blocking courses can also be used to terminate a wall and provide additional support to the wall. They can be used as a decorative element, adding visual interest to the wall. In addition, blocking courses can be used to provide a physical barrier to protect occupants from the elements and to reduce the risk of fire and smoke spreading throughout a building. They can also aid in the control of sound, heat, and light, as well as providing a layer of insulation to protect against air leakage. Blocking courses can be constructed of various materials, including concrete, masonry, wood, metal, or a combination of materials. The choice of materials will depend on the specific requirements of the project, including the desired aesthetics, structural requirements, and environmental factors. In summary, a blocking course is a construction element used to create a transition between two different heights in a wall. It provides structural support to the wall while also creating an aesthetically pleasing transition. Blocking courses can also be used to terminate a wall, provide additional support, and offer protection against the elements, fire, and sound. The choice of materials used for a blocking course will depend on the specific requirements of the project.

Blocking Course is an architectural concept that involves the strategic placement of walls, corridors and other structures to ensure the privacy of occupants, reduce sound transmission and even improve energy efficiency. Blocking Course is also widely used in building code requirements to provide fire safety and security. The Blocking Course is designed to provide a physical barrier to protect occupants from the elements and to reduce the risk of fire and smoke to spread throughout a building. It also aids in the control of sound, heat and light, as well as providing a layer of insulation to protect against air leakage. Blocking Course is usually constructed of concrete, masonry, wood, metal or a combination of materials.

Masonry blocking course is a type of construction element used to create a transition between two different heights in a wall. It is typically composed of a row of masonry units such as bricks, stones, concrete blocks, or precast concrete planks, that are laid similar to a regular masonry course, but with the individual masonry units cut to different heights. The purpose of the blocking course is to provide a gradual transition between the two heights of the wall, while also providing structural support. Masonry blocking courses can also be used to terminate a wall, and provide additional support to the wall.
