They also prevent water from entering through the outside, and structural stability. The construction material and the design of the cavity wall may vary, and the durability of these walls is also dependent on the tying method and product for tying (wall tie) employed. Wall tie is the primary component that determines the strength of the wall.

Builders utilize wall ties in cavity walls to secure the two walls in place to stop them from sagging or bowing. Cracks in the brickwork that are horizontal or external rendering, as well as building blocks are often caused by the deficiency of the cavity wall ties. 

In older properties, it's typical to see steel wall ties. These are corroding and rusting and need replacement. When the wall ties in the cavity begin to corrode, they expand to many times their original size which causes walls to break in the mortar joints. This can cause major destruction and even it can cause the walls to collapse.

The form and thickness of wall ties are determined by specific factors such as the size of the area of brickwork uncontrolled as well as the amount of wind exposure as well as the dimensions of the cavity height of the structure and the general design of the construction.
