What are wall ties?

Wall ties are an essential component of masonry structures, providing a secure connection between the inner and outer walls of a building. Wall ties are used to prevent the walls from separating or collapsing due to lateral or wind loads. In this article, we will discuss the importance of wall ties in masonry structures and how they are used to ensure the stability of the building.



Masonry structures consist of two or more layers of masonry, such as bricks or concrete blocks, which are bonded together with mortar. The inner and outer layers of masonry are connected by wall ties, which are typically made of galvanized steel or stainless steel. Wall ties are usually spaced at regular intervals along the height and width of the building, and are embedded in the mortar between the two layers of masonry.


The primary function of wall ties is to transfer the lateral loads that are applied to the outer wall to the inner wall. Lateral loads can be caused by wind, earthquake, or other external forces that act perpendicular to the wall. Without wall ties, the outer wall of a masonry structure can easily separate from the inner wall, leading to a collapse of the building.

Wall ties are also used to prevent moisture from penetrating the wall cavity between the inner and outer layers of masonry. Moisture can cause damage to the masonry, insulation, and other building materials, leading to structural problems and health hazards such as mold and mildew.


The design and installation of wall ties are critical to the stability and longevity of a masonry structure. The type and spacing of wall ties depend on several factors, including the height and width of the building, the materials used for the masonry, and the environmental conditions in the area.


In addition to providing stability and preventing moisture penetration, wall ties must also be installed correctly to avoid damage to the masonry. Improperly installed wall ties can cause cracks or damage to the masonry, which can compromise the structural integrity of the building.


It is important to note that wall ties are not a permanent solution to masonry stability. Over time, wall ties can corrode or deteriorate, and may need to be replaced or supplemented with additional wall ties. Regular inspections of the wall ties, as well as the overall condition of the masonry, can help identify potential problems and ensure that the building remains safe and stable.


Wall ties are an essential component of masonry structures, providing stability and preventing moisture penetration. The design and installation of wall ties are critical to the safety and longevity of the building, and regular inspections can help identify potential problems. It is important to work with a qualified and experienced contractor to ensure that wall ties are installed correctly and that the masonry structure remains safe and stable for many years to come.
