The Most Common Types of Masonry Unit Joints
Here are the most common types of masonry unit joints, along with their descriptions and images:
Concave joint:
- A recessed profile, often used for aesthetic purposes and for its effectiveness at shedding water.
- Created by tooling the mortar with a curved tool.
Flush joint:
- The mortar is level with the surface of the masonry units.
- Often used when the masonry surface will be plastered or painted.
- Easier to construct than other types of joints, but may not be as weatherproof.
Struck (stroked) joint:
- The excess mortar is removed to create a smooth, even surface.
- Often used for a clean and classic look.
- Can be more time-consuming to create than other types of joints.
Weathered joint:
- A sloped profile that sheds water and prevents staining.
- Often used on horizontal joints.
- Can add visual interest to a masonry wall.
Raked joint:
- The mortar is raked out to create a groove or channel.
- Often used for a rustic or textured look.
- Can provide a good key for plaster or other finishes.
Raised (bead) joint:
- The mortar is raised above the surface of the masonry units to create a decorative effect.
- Often used for a formal or elegant look.
- Can be more difficult to keep clean than other types of joints
Vee joint:
- A V-shaped profile, often used in brickwork.
- Can add visual interest and help to shed water.
- Not as strong as some other types of joints.
Extruder (squeezed) joint:
- Created by forcing mortar through a nozzle, resulting in a uniform and consistent appearance.
- Often used for quick and easy installation.
- Not as strong as some other types of joints and may not be as weatherproof.
The type of joint you choose will depend on the desired aesthetic, structural requirements, and exposure to the elements. Consider consulting with a professional mason to determine the best option for your project.
