If you own a property, especially one constructed with cavity walls, you've probably heard about wall ties and their importance. Wall ties, though often unnoticed, are crucial to maintaining the stability and safety of your structure. Over time, these ties can corrode, weaken, or fail entirely, making wall tie replacement an essential process. In this blog, we’ll delve into everything you need to know about wall tie replacement, including types of wall ties, signs of damage, and how to find "wall tie replacement near me". We will also look at how companies like Insite Southern can assist you with professional wall tie replacement.
What Are Wall Ties and Why Are They Important?
Wall ties are metal components used to connect the inner and outer leaves of a cavity wall, providing structural support. These ties ensure that the load is distributed evenly across the wall, preventing movement, bulging, or even collapse. Typically made from steel or galvanised metal, wall ties are embedded during construction to reinforce both wall panels. However, like all materials exposed to harsh weather conditions, wall ties can degrade over time, requiring replacement.
Failure to replace damaged wall ties can lead to structural issues like cracking or even the separation of wall leaves. To avoid such dangers, regular inspection and timely wall tie replacement are key.
Common Signs You Need Wall Tie Replacement
How do you know if your property might need wall tie replacement? Here are some of the most common signs of damaged or failing wall ties:
Horizontal Cracks in Brickwork: Cracking along mortar lines is often an indication that wall ties have corroded and expanded, creating stress on the bricks.
Bulging Walls: Bulging or uneven walls are often a consequence of wall ties losing their integrity, leading to instability between the two leaves of the wall.
Mortar Bed Cracks: Cracks in the mortar beds, especially around the level of wall ties, are usually an indication of degradation or corrosion of these ties.
Rust Stains on Brickwork: Rust bleeding through the walls is an indicator of corroding wall ties. When wall ties rust, they expand, causing the mortar to crack and allowing rust stains to show on the exterior.
If you notice any of these signs, it’s wise to have a qualified professional conduct an inspection.
Types of Wall Ties
Wall ties come in different varieties, suited to different construction types and needs. Here are some of the common types of wall ties:
Butterfly Ties: Often used in older homes, butterfly ties are shaped like two wings joined in the middle, similar to a butterfly. They are best suited for low load-bearing situations.
Double Triangle Ties: These are a classic option, generally used in traditional brickwork, with a zigzag shape that provides extra grip. Double triangle ties were common in older homes but are rarely used today because modern standards call for more robust options.
Channel Wall Ties: Modern constructions tend to use channel wall ties. They allow for the inner and outer wall leaves to move slightly, which makes them ideal for areas prone to thermal expansion or ground movement.
Rectangular Wire Ties: Made from galvanised or stainless steel, these ties are used for cavities with small air gaps. They are versatile and offer excellent stability for brick and block construction.
Modern Stainless Steel Ties: Nowadays, stainless steel wall ties are standard due to their high corrosion resistance. They provide long-lasting support and meet modern building regulations, making them a popular option for new builds and wall tie replacements.
Each type of wall tie serves its own purpose, depending on the type of wall, cavity size, and construction conditions. When considering wall tie replacement, it’s vital to understand which type is suitable for your specific building.
Why Wall Tie Replacement is Crucial
Wall ties are usually made from galvanised metal, but despite this protection, they can still corrode due to moisture ingress and exposure to salts. This is particularly common in properties built between 1920 and 1981, as the wall ties used during that period were prone to corrosion. Corroded wall ties expand, causing the surrounding brickwork to crack. This expansion can eventually lead to structural failure, particularly in older houses that lack modern protective features.
Replacing wall ties in a timely manner can prevent significant and costly structural damage. It also helps in maintaining the overall value and safety of your property, ensuring that the walls are stable and secure.
The Wall Tie Replacement Process
Wall tie replacement is a straightforward but essential process that should be carried out by experienced professionals like Insite Southern. Here’s how the process typically unfolds:
Inspection and Survey: First, a thorough survey is conducted to identify the location and condition of the existing wall ties. Specialists may use metal detectors or endoscopic cameras to inspect the wall cavity.
Mapping: The existing wall ties are marked on the walls, and corroded ties are mapped to establish the extent of replacement needed.
New Tie Installation: The next step involves drilling small holes at intervals into the brickwork and inserting new stainless steel wall ties. These ties are driven into place with specialised equipment that secures them between both leaves of the cavity wall.
Isolating Old Ties: In most cases, old corroded ties need to be isolated to prevent them from causing further damage. This is done by removing sections or using chemicals to de-bond the ties.
Finishing Touches: Once the new wall ties are in place, any holes are patched up and the brickwork is repaired to its original condition.
The entire process takes anywhere between one to three days, depending on the size of the wall area and extent of replacement required.

Preventive Maintenance for Wall Ties
To avoid costly repairs and maintain the structural integrity of your home, regular checks are advisable. Here are a few preventive tips:
Regular Inspections: Have your cavity wall ties inspected every 20 years or sooner if you notice any tell-tale signs of damage.
Proper Drainage: Ensure your property has adequate drainage to avoid water seeping into walls and corroding ties.
High-Quality Replacements: Always opt for stainless steel ties when replacing older ones to ensure longevity and resistance to corrosion.
Preventive measures might require some investment initially, but they can help you save a lot on expensive replacements in the future.
