What Exactly are Cavity Wall Ties?
Cavity wall ties are metal components that hold together the inner and outer sections of the masonry wall together. The main function of the interior wall is to bear the structural load. The cavity wall ties ensure this load-bearing capacity is extended to the outer wall as well.
Wall ties function by transferring this stability to the outer wall. Hence, it ensures both walls maintain their position effectively. These ties are usually crafted with factors such as ground movement, temperature-related expansion, and water penetration kept in mind. Though they are usually made of durable and sturdy materials, weathering and other manufacturing factors can chip into their lifetime.

Another symptom of its failure could be the separation of the mortar bed from the brick or stone. This indicates wall tie corrosion.
