What Are Cavity Wall Ties and Why Do They Fail?
Cavity wall ties are metal components built into cavity walls to hold the inner and outer leaves of brickwork together. Their job is to keep the structure stable while allowing moisture to drain through the cavity. Over time, especially in older properties, these ties can begin to corrode or fail. In Cardiff, exposure to wind-driven rain and moisture can accelerate corrosion, particularly in homes built before stainless steel wall ties became standard. As the metal rusts, it expands, putting pressure on the surrounding mortar and brickwork. This often leads to cracking, bulging walls or movement in the external masonry. In some cases, wall ties may not have been installed correctly during construction, leaving walls poorly supported from the start. At ASRS Ltd, we understand how local weather conditions and building styles contribute to wall tie failure. We assess each property carefully to determine whether replacement is required and ensure the correct solution is put in place.
Common Signs of Wall Tie Problems
The signs of cavity wall tie failure are often visible on the outside of a property, although they can sometimes go unnoticed until damage becomes more severe. One of the most common indicators is horizontal cracking in the mortar joints of brickwork, often following a straight line across the wall. Stepped cracks that follow the mortar joints can also appear, particularly around windows or on gable walls. In more advanced cases, the external wall may begin to bulge or bow outward, which is a serious structural concern. These issues occur when corroding wall ties expand and force the brickwork apart. You may also notice cracking internally, although this is less common. In coastal or exposed areas of Cardiff, wall tie corrosion can progress more quickly due to higher moisture levels. At ASRS Ltd, we use specialist detection equipment to locate and assess wall ties within the cavity. This allows us to confirm the condition of the ties and recommend appropriate action before further damage occurs.
Our Wall Tie Replacement Process
At ASRS Ltd, we follow a proven and reliable process for cavity wall tie replacement that ensures long-term structural stability with minimal disruption. Once our inspection confirms that wall tie failure is present, we plan the installation of new ties based on the size, age and construction of your property. We install high-quality stainless steel replacement wall ties, which are resistant to corrosion and designed to last the lifetime of the building. The new ties are inserted into carefully drilled holes at precise locations to ensure proper spacing and support. Depending on the wall type, the ties are secured using resin or mechanical fixings. In most cases, the original corroded wall ties are isolated to prevent further expansion and damage. Once the new ties are in place, we make good the external brickwork, matching the mortar as closely as possible to maintain the appearance of your property. Our process is efficient, clean and carried out with care at every stage.
