What Are Cavity Wall Ties?

If you are unfamiliar with property repairs, then we can break the process down for you. We would be more than happy to chat to you over the phone about cavity wall ties, however, we have provided a short guide on cavity wall ties for your information. 

In most cases, you will find that cavity wall ties are made of metal coated in bitumen or zinc. Cavity wall ties were introduced in the early 20th century and builders use wall ties to hold separated walls together forming a "cavity wall system". 
Nowadays, we use the current technology and products when installing cavity wall ties which means they are much more successful than the original ties, however, the technique to install the ties is very important. If you have noticed that your walls are showing signs of bulging or cracking then the wall ties may have begun to fail and we would recommend that you get in touch with a property care expert as soon as possible.

Signs of Damaged Wall Ties and Wall Tie Corrosion

Don’t panic. If you are concerned about damaged wall ties within your home, there are a few things you can check. If you notice any of the following tell-tale signs then this may indicate wall tie damage or failure and we recommend that you contact a wall crack repair expert at Richardson and Starling. 
  • Vertical or horizontal cracks in brickwork
  • Bulging Brickwork
  • Cracks or separation of window reveals
  • Lintels sagging
These signs will most likely get worse over time and in most cases, the visual damage will become more noticeable. If you have noticed any of these problems, we would suggest that you get in contact with our cavity wall tie team. 

We are confident that a diagnosis of the problem will be made and the proper specification for the remedial work given. We guarantee that we will provide you with a competent and trustworthy repair service that keeps your home in great condition.

Defective Cavity Wall Ties

If you have noticed vertical or horizontal cracks in brickwork, then something may be wrong with your cavity wall ties. Bricks often crack due to the expansion of corroded wall ties. This happens as the wall tie corrodes, rust or metallic oxide is produced and the wall tie thickness expands and takes up more space in the mortar joint of the wall than the original tie did. The bricks above and below the tie will begin to shift as they are being forced apart by the wall tie cracking the mortar bed. 
Bulging Brickwork can be another sign of defective cavity wall ties or there may not be enough wall ties installed when the wall was built. This bulging can occur again due to the corrosion of wall ties and the wall tie breaking free from its bond with the brickwork mortar. The wall can then move due to building loads or wind pressure. The brickwork has no choice but to bulge outwards as it is not tied into the building structure properly.

Similarly, if you have noticed cracks or separation of the window reveals this could be a sign of expansion and movement which is caused by defective wall ties not tying the walls together. You may also have defective wall ties if you noticed that the depth of the window reveal is inconsistent.
Evidence of Lintels above doors or windows, Lifting or Sagging can be another sign that your wall ties have broken their bond and this may also be caused by expansion movement. Lintels can be pushed upwards or downwards when this occurs. 

If you have noticed any of these signs there are things that we can do to diagnose these problems. This should be left in the hands of an expert to avoid any further damage. 

How do I Know if I Have a Cavity Wall?

The first think to do is determine the construction type of the wall. When brickwork is exposed you can tell by the brick pattern if the wall is solid or has a cavity construction. If the bricks have been laid in such a way that you have the majority of bricks laid lengthways and then you have a course of bricks that has been laid width ways then this is a good sign that the wall is solid.

If the brickwork is rendered one method that Richardson & Starling use is to drill through the outer wall of your property. A member of our team will be able to check if the wall is a cavity construction by using our borescope to inspect the hole to determine the wall construction.

History of Wall Ties

Where did wall ties come from? If this is a question that you have been wanting to ask, we have the answer for you. Originally, wall ties were used for housing construction and have become a common tool which is used for building properties and homes in the UK.

It is now the standard that any modern property is built with a cavity wall. Traditional 225mm solid walls have been replaced by the cavity wall construction. Its purpose is to split the solid wall with a thicker wall in two parts and a gap in the middle. Therefore, the wall ties effectively tie the two walls together, improving the stability of the walls. 

The cavity gives resistance to weather penetrating the property living space and helps improve the thermal performance of the wall.
