Remedial
Wall Ties

Keep your walls standing strong and secure with cavity tie replacement and lateral support solutions.

What are remedial wall ties?

Remedial wall ties are crucial, non-invasive solutions designed to stabilise compromised walls around your home. They are used for both cavity and solid walls that have lost their connection to the main structure, often impacting the exterior, load-bearing walls.

Also referred to as wall tie replacements or lateral restraints, remedial wall ties play a key role in re-securing walls to ensure your home’s stability and safety.

When might remedial wall ties be essential for my home?

If your home’s walls are constructed with two separate layers of brick and a gap in the middle, you have cavity walls. Similarly, if your home features solid walls, they too rely on a stable connection to maintain structural integrity. Wall ties are embedded into the brickwork during construction to keep these walls securely connected. However, over time, these wall ties can fail, leading to instability, and in severe cases, walls may lean or collapse.

The primary causes of wall tie failure include corrosion from exposure to moisture and water, disconnection caused by subsidence and damage from expanding brickwork.

Remedial wall ties serve as a replacement for both cavity and solid wall ties, ensuring the permanent stability of your walls and, more importantly, your home’s structure.

Symptoms Of Wall Tie Failure To Look Out For Around Your Home

Gap around windows

Unfortunately, detecting failing wall ties is challenging since they’re concealed within the walls, invisible to the naked eye. However, one reliable indicator of structural issues is the appearance of gaps around your windows. Such issues, including wall tie corrosion or foundation settlement, can lead to the external wall detaching from the internal load-bearing walls. Typically, walls will start to lean outward at the top. If you notice gaps that are wider at the top and narrower at the bottom, it’s a strong indication that your home may be experiencing wall tie failure and requires remedial wall ties

Leaning, bulging walls

If your home is an older, pre-1930s build, it’s probably constructed with solid brickwork through to the ground. This type of wall construction, while common in the past, was phased out due to reliability issues. Despite being ‘solid’ in name, these walls are exposed to environmental changes and poor construction quality, leading to leaning or bulging walls over time. Should you observe your walls bowing outward in the middle or detaching from the roof, it may be an indication that your home is experiencing structural challenges and could benefit from a remedial wall tie solution to improve stability.

Cracks near corners

If you live in a modern brick building, it likely has cavity wall construction made from extruded clay brick. Over time, the exterior wall, due to exposure to the elements, can expand in a process known as brick growth, causing cracks near the corners of your home. While these cracks are structural concerns on their own, an additional, unseen issue could be the snapping of cavity wall ties that connect internal to external walls. If your home is showing corner cracks and signs of brick growth, it’s possible your cavity ties need to be replaced.

Sometimes the symptoms of wall tie failure might just be cosmetic blemishes, but others can signal a more serious structural problem.

Leaving these walls unattended could compromise structural integrity, resulting in expensive rebuilding of walls and reduced value of your home. They may even be a safety concern for your family.

Frequently Asked Questions

What are wall ties and why are they important for my home?
Wall ties are essential components in the construction of the walls of a home. They act as a connection between the inner and outer structures, ensuring the walls act as a single unit, providing structural stability and helping to prevent potential collapse.
Indicators that wall ties may need attention include vertical cracks in your brickwork near corners, bulging or bowing of walls and gaps appearing between your bricks and windows. An assessment by one of our experts can provide a definitive answer.
Repairing or replacing wall ties doesn’t involve removing old faulty ties or your bricks. They stay in place. Instead, new ones are installed from the outside. This process typically includes drilling into the brickwork, inserting the new ties and making good any disturbance to the wall’s appearance. These new ties are known as remedial wall ties and come in varying lengths from 220 mm to 1 m, depending on the age of your home and the design of your walls.
Mostly, yes. The majority of our projects are completed within one or two days. However, the duration varies depending on the complexity of the repair, the area size and the access requirements.
Definitely not. Buildfix will work around your schedule and needs. Some projects may require indoor access, but we’ll let you know in advance if furniture needs to be moved to access the walls we’re targeting for repair.
