Brick masonry involves installing bricks into a wall to form a structure. The bricks must be evenly distributed throughout the wall, and the thickness of the mortar joint must be 12 mm or more. There are different types of bricks; channel, hollow, hollow brick and others. A mason must carefully mark the layout of the bricks on the foundation wall with a level, a theodolite, or chalk. A mason must also make sure that the walls are heavy and that the height is correct. After laying the bricks in the foundation wall, a second mason should follow the first mason with half bricks to make sure the bricks are level and heavy.
Brick masonry is prone to cracking and if not repaired can lead to serious structural failure. This is because bricks are prone to wear due to exposure to weather conditions. Wind, temperature, and humidity promote the expansion of the material, which creates internal forces that can cause fractures. Apart from this, smoking is another cause of fractures. Smoke contains high temperatures and humidity, and these elements can cause bricks to crack.
Bricks are generally produced by one of two processes. In the dry-press process, the clay mix is pressed with more hydraulic force, resulting in a thicker brick with better edges. This method requires more equipment and is generally more expensive. The heat used during this process also determines the color of the brick.
Head and carriage ties are the most common brick ties. The heads and carriages are vertically aligned and overlap half their length. The header is the shortest face of the brick. Topped brick masonry is most common for walls that are one brick thick. In addition to header bonds, Flemish bonds are another option. If you want to create a wall that is three quarter bricks thick, head and stretcher gluing is a great option.
Bricks are available in many colors, varieties, and types. The brick masonry process varies depending on the types of bricks used. Terracotta, stone and concrete are also often used. There are also several varieties of clay bricks, including grooved bricks and grooved bricks. These bricks can vary in size, shape, and color.
Bricks are not waterproof and often have air voids. For these reasons, structural walls may have an impervious layer, such as tar paper. A brick veneer may also include weep holes in the base for drainage. Similarly, concrete blocks, natural and cultured stone, and veneer are sometimes used to form a wall.
