What Are Wall Ties?
Wall ties are small components used to tie together internal and external leaves of a cavity wall. They are integrated into the cavity of a wall throughout the construction process. Wall ties function by having the ends of each tie bedded into the mortar bed at regular intervals. They are designed to cover the majority of the cavity as a means to successfully adjoin the stable inner lead to the outer leaf and increase structural stability. Wall ties are further used to prevent water from transferring from the outer leaf to the inner and accommodate any small movement the walls might have to sustain.
What Causes Wall Tie Failure?
Wall ties are most likely to experience failure due to two main occurrences; construction issues or wall tie corrosion. If the quality of a construction project isn’t up to the standard it should be for example, wall ties can quickly fail over time. Cavity wall ties can be found to fail due to them having been incorrectly spaced, fixed or cut too short. In addition, wall ties fail when poor quality mortar was used during the construction of a build which means it fails to provide enough bond for the ties.

Some wall ties are claimed to I theory last the lifetime of a build, however, in practice wall ties are known for lasting an approximately 15 – 20 years before they start corroding. Wall tie replacement is thus a widely used and common repair method which many properties need to undergo.
How Serious Is Wall Tie Replacement?
Although wall ties may be perceived to be a small aspect of a property’s structure, they in fact contribute significantly towards the overall stability of the structure. The maintenance and replacement of wall times when necessary is thus of critical importance when intending to keep the structural stability of a property up to healthy standards. The more promptly structural repairs are conducted on a build in need of such, the less costly these repairs will be as they will be able to prevent any subsequent damage from appearing as a result of a delayed repair. Maintaining a frequent upkeep of structural elements such as well ties thus effectively contributes towards the overall health and wealth of a property.
