Curved masonry walls can be created three ways. If the radius is large enough, standard brick can be used. If the radius is small, radial brick (curved brick manufactured to a specific radius) should be used. The third way is to cut standard brick to create a shorter inside length. STANDARD BRICK The use of standard brick is more cost-effective than using radial brick. However, as the radius of a wall gets smaller, standard brick create a rougher wall texture because stretchers laid in running bond project outward from course to course. Also, as the radius of a curved wall decreases, outside head joints become wider. This not only can be unattractive, it also can be structurally unsound. Table 1 shows the minimum radii needed to create a curved surface with brick of different sizes and in different positions. RADIAL BRICK Radial brick normally create the most attractive small-radius walls, though this is tempered by the position of the brick. Radial brick can be specified for walls with a radius as small as four inches (the thickness of one brick). As the radius of a wall gets larger, radial brick appear more like standard brick and become less necessary to create a pleasing curve. Radial brick can be specified with the curved radius on the inside surface, the outside surface or both. CUT BRICK An alternative to radial brick is to cut the ends of brick at an angle to allow for a tighter radius without increasing mortar joint thickness.
