Cavity wall ties are metal fixings installed during the construction of a property to connect the inner and outer leaves of a cavity wall. Although they are hidden from view, they play a vital role in holding both walls together while allowing the cavity to perform its insulating and moisture-resistant function.

Most properties built with cavity walls rely on wall ties to provide stability and help the external brickwork resist wind loads and movement. Depending on the age of the property, the wall ties may have been manufactured from mild steel or stainless steel.

Older mild steel wall ties, particularly those installed between the 1920s and the late 1980s, are more susceptible to corrosion over time. As they rust, they expand, which can cause horizontal cracking in the mortar joints, bulging brickwork, and eventually wall tie failure if left untreated.

Modern stainless steel wall ties are highly resistant to corrosion and are used when carrying out remedial wall tie replacement to provide a long-term solution.

Corroded or failed wall ties can compromise the stability of your property’s cavity walls, leading to horizontal cracking, bulging brickwork, and, in severe cases, structural issues. Our specialist wall tie replacement service safely installs high-quality stainless steel remedial wall ties to restore the structural integrity of your walls.

Every installation is carried out by experienced technicians using industry-approved methods, with minimal disruption to your property. We also isolate existing corroded wall ties where required to prevent further damage.

Whether you’ve had a wall tie survey or are experiencing signs of wall tie failure, we provide professional advice, competitive pricing, and guaranteed workmanship throughout the UK.

A wall tie survey is a specialist inspection carried out to assess the condition, type and spacing of the wall ties within a cavity wall. As wall ties are hidden inside the wall, a visual inspection alone is not sufficient, so specialist equipment is used to accurately assess their condition.

Our survey begins by taking metal detector readings across the external walls to locate the existing wall ties and identify their approximate spacing and pattern. Once suitable locations have been identified, we carefully drill a number of small inspection holes into the mortar joints. These holes are kept to a minimum and are made as unobtrusively as possible.

A high-resolution borescope camera is then inserted through the inspection holes, allowing us to examine the wall ties inside the cavity. This enables us to identify the type of wall tie, assess the level of corrosion, check the embedment and installation, and look for any signs of failure or defects.

Following the inspection, we produce a detailed report complete with borescope photographs, our findings, and any recommendations. To ensure complete transparency, our recommendations are based on the Building Research Establishment (BRE) corrosion grading charts – the recognised industry standard for assessing wall tie condition. This means our advice is evidence-based, impartial, and directly linked to the level of corrosion identified during the survey, giving you confidence in the results.

Wall tie failure can occur when existing cavity wall ties begin to deteriorate, most commonly due to corrosion over time. As the ties lose their ability to provide restraint between the inner and outer leaves of masonry, movement and cracking can develop within the external walls.

Common signs associated with wall tie failure include:

• Horizontal cracking along the mortar joints, often appearing at regular intervals where wall ties are located.
• Stepped cracking within the brickwork, which may indicate movement between masonry panels.
• Bulging or bowing of external masonry panels caused by a loss of restraint between the inner and outer leaves.
• Vertical cracking around openings, corners, or areas where movement has occurred.
• Loose or deteriorating brickwork due to reduced stability of the outer leaf.
• Mortar joint deterioration or localised cracking around wall tie positions.
• Water staining or damp-related issues caused by damaged or poorly performing cavity wall components.

Early identification of wall tie corrosion is important, as remedial action can often be undertaken before significant structural movement or damage occurs. A professional wall tie inspection can determine the condition, type, and performance of existing wall ties and establish whether remedial measures are required.
