What material is used to secure the backing wall and brick in brick veneer buildings?

In brick veneer construction, the backing wall is typically secured using galvanized metal ties. These ties play a crucial role in connecting the brick veneer to the structural backing, which is usually made of wood or metal. The use of galvanized metal ties is favored because they provide strong support and resistance to corrosion, ensuring the durability and stability of the wall assembly over time.

The metal ties are attached to the studs or framing of the backing wall and extend into the mortar joints of the brick veneer, creating a secure integration between the two materials. This connectivity is essential not only for structural integrity but also for accommodating any thermal expansion and contraction that may occur due to temperature changes.

This choice ensures a reliable and long-lasting connection that is essential in maintaining the overall performance and safety of the building. The other materials listed serve different purposes in construction and do not provide the same degree of structural support necessary for securely fastening the brick veneer to the backing wall.
