How to Install Masonry Ties
To install masonry ties, start by understanding the importance of these ties in brick wall construction.
Masonry ties are essential for providing lateral support and tying the brick back to the structure.
Relief angles or shelf angles are commonly used to support the weight of the brick veneer.
Another type of masonry tie is the dovetail masonry anchor, which fits into horizontal mortar joints.
Additionally, ladder-type systems with wire anchors are used for concrete block backup walls.
The installation process for masonry ties involves securely attaching them to the structure and ensuring proper spacing.

Did You Know?
1. The concept of using masonry ties to secure and stabilize brick or stone walls dates back to ancient Egypt, where they used small wooden dowels to reinforce their structures.
2. In the early 20th century, masonry ties were commonly made from iron and referred to as “wall anchors.” However, due to concerns over corrosion and rust, stainless steel became the preferred material for masonry ties in the 1960s.
3. Did you know that there is a specific formula to determine the number and spacing of masonry ties needed? For brick walls, the general rule is to have at least one masonry tie per every 2.67 square feet (0.25 square meters) of wall area.
4. The use of masonry ties isn’t limited to traditional brick or stone walls. They are also commonly used in the construction of cavity walls, which consist of an inner and outer layer of masonry separated by an air gap. The ties help bond the two layers together.
5. Masonry ties provide more than just structural support. They also play a vital role in preventing the occurrence of cracks and bulges in masonry walls that can result from thermal expansion and contraction.
Importance Of Masonry Ties
When it comes to brick wall construction, the importance of masonry ties cannot be understated. Masonry ties are essential in providing the necessary support and stability to brick veneer, ensuring the structural integrity of the entire wall. Without these ties, the bricks can become loose, leading to potential collapse or other safety hazards.
To summarize:
- Masonry ties play a crucial role in brick wall construction.
- They provide support and stability to the brick veneer.
- Structural integrity of the wall depends on masonry ties.
- Without ties, bricks can become loose and pose safety hazards.
“Masonry ties are like the backbone of a brick wall, holding it together and preventing potential disasters.”
The Use Of Relief Angles Or Shelf Angles
One common method for supporting the weight of the brick veneer is to use relief angles or shelf angles. These metal brackets are typically installed at regular intervals along the wall, providing a level surface for the bricks to rest upon. This helps distribute the weight evenly and prevents excessive stress on any one point of the wall.

Why Masonry Ties Are Needed
Masonry ties are vital for connecting and securing the brick veneer to the underlying structure. They act as connectors, ensuring the brick remains firmly attached and providing essential lateral support. In regions prone to high wind loads or seismic activity, masonry ties become even more critical as they help resist lateral forces that could otherwise lead to the shifting or collapse of the brickwork.
Dovetail Masonry Anchors
Dovetail masonry anchors are a specialized type of masonry tie that neatly fit into horizontal mortar joints. Their distinctive dovetail shape, with interlocking “teeth,” ensures remarkable strength and stability. Offering an easy installation process, these anchors provide a reliable solution for securing brick veneer.
Wire Anchors For Concrete Block Backup Walls
When it comes to concrete block backup walls, a ladder-type system with wire anchors is commonly used. This system consists of horizontal wire anchors embedded into the joints of the concrete block, forming a ladder-like pattern. The wire anchors are then connected to masonry ties in the brick veneer, ensuring a strong and stable connection between the two components.
- Concrete block backup walls often use a ladder-type system with wire anchors.
- Horizontal wire anchors create a ladder-like pattern in the joints of the concrete block.
- The wire anchors are connected to masonry ties in the brick veneer for a secure connection.
The use of a ladder-type system with wire anchors provides a reliable and sturdy connection between the concrete block backup walls and the brick veneer.
Installation Process
The installation process for masonry ties can vary depending on the specific type and design of the ties being used. However, the general steps are as follows:
-
Begin by marking the locations where the masonry ties will be installed. These locations should be in line with the horizontal mortar joints and evenly spaced along the wall.
-
In the case of dovetail anchors, carefully insert the anchors into the mortar joint, making sure they are fully embedded and secure. Ensure that the anchors are spaced according to manufacturer specifications.
-
For wire anchors in concrete block backup walls, start by installing the horizontal wire anchors into the joints of the concrete blocks, following the ladder-like pattern. Secure the wire anchors in place using appropriate fasteners.
-
Connect the masonry ties to the installed anchors. This can be done using mechanical fasteners, such as screws or bolts, depending on the specific tie design.
-
Repeat the installation process for all the masonry ties, ensuring that they are properly connected and securely fastened.
By following these installation guidelines, you can ensure that your masonry ties are properly installed and provide the necessary support and stability for your brick wall construction.
Frequently Asked Questions
What is the spacing for masonry ties?
The spacing for masonry ties is determined by various factors, including stud spacing and code requirements. To ensure structural integrity, ties should be spaced vertically every 12” or 16” and horizontally every 16” or 24”. These measurements allow for proper support and meet code standards, which generally mandate one tie for every 2.67 square feet of wall area. It is important to secure the ties by nailing them into the studs, and they are typically installed progressively as the mason builds the wall with brickwork.
How do masonry ties work?
Masonry ties are essential in ensuring the stability of brick veneer on a building. These ties are specifically designed to fit into the horizontal mortar joints, connecting the brick to the underlying structure or backup wall. By securing the brick in place, masonry ties prevent any potential risk of the veneer falling off. An example of a masonry tie is the dovetail masonry anchor, which perfectly fits into a dovetail insert, further enhancing the structural integrity of the brickwork.
What are masonry wall ties?
Masonry wall ties are essential components used to connect separate layers of masonry or attach masonry veneers to a structural backing system. These ties can be in the form of wires or sheet metal devices. When connecting multiple masonry wythes, wall ties ensure the stability and structural integrity of the entire masonry construction. Similarly, when used as veneer anchors, these wall ties securely attach the masonry veneer to the underlying structural support, providing both stability and an aesthetically pleasing appearance. Masonry wall ties play a crucial role in maintaining the strength and overall performance of masonry structures.
Where should brick ties be placed?
When determining the placement of brick ties, it is important to evenly distribute them over the entire wall area in a staggered pattern. This ensures that the ties provide balanced support and stability. However, it is crucial to alter the wall tie pattern around openings such as windows, doors, roof verges, unreturned or unbonded edges, and un-tied vertical movement joints. By modifying the brick tie placement in these areas, the structural integrity of the wall can be maintained, addressing any potential vulnerabilities and allowing for a secure and durable construction.
