What are Wall Ties?
Wall ties, also known as ‘brick ties’, are used in buildings with cavity walls. Cavity wall ties are an important structural part of any building.
They’re required to tie the visible protective outer cavity of brickwork or blockwork of a building together with the inner wall or masonry skin (the structural and load bearing part of the building). Ties are placed in the cavity wall during construction of a property and spans the cavity.
Identifying Wall Tie Failure
After a while, all Wall Ties will need replacing. So if your property is old, then it’s recommended that you have your wall checked for failed wall ties. We have specialist equipment and endoscopes that we can use to inspect the condition of your wall ties and diagnose any potential issues.
Visually, it’s hard to tell if wall ties have failed and to what extent. If a wall has horizontal cracks in your outer wall, then it’s likely that your cavity wall ties need replacing. When checking your external walls there are a few visual indications to look out:
- Horizontal masonry cracking
- Cracks on rendering
- Bulging or bowing walls or brickwork
- Separation of window reveals
If you suspect that your wall ties have failed it’s important that you get a professional diagnosis before the issue escalates. We can help you diagnose any issues and advise you on how to replace your wall ties.
Unfortunately, wall ties that are made of mild steel will corrode eventually. Wall ties in properties constructed before 1940 used many different materials and it is almost impossible to say how long these ties will last.
According to various sources, properties constructed between 1940 and the 1960’s can be roughly estimated to:
- Wire Ties – between 15 and 30 years
- Strip Ties – between 30 and 60 years
As for properties constructed between the 1960’s and early 1980’s:
- Wire Ties – between 13 and 26 years
- Strip Ties – between 23 and 46 years
No problem, we can work around cavity fill insulation. When working with walls that have cavity fill insulation it is important that you don’t use any retrofit or remedial ties. These ties have resins that need to chemically react in order to set, these resins may affect your insulation. We also make sure that we’re careful when installing new wall ties as not to cause any loss in the thermal efficiency of the insulation.
The cost of cavity wall tie replacement depends on a number of different factors. These factors include the building size, the total wall space, type of brick used and the type of wall tie you require. It’s not as expensive as you might think, contact us today and we can give you a competitive quote.
