• What is cavity wall tie?
• A cavity wall is an artificial space that is
  created between the outside facing wall and the
  inside facing wall. There are several advantages
  to this, such as including insulation, reducing
  thermal transfer and keeping your interior warm,
  as well as preventing rainwater from entering
  your building. Cavity walls are most commonly
  found in properties built after the 1930s, but
  there is a simple way to determine if you have a
  cavity wall or a solid brick wall. The first
  thing to remember is that a solid brick wall will
  only be as wide as approximately the width of an
  inner wall.

• If you have a cavity wall then it is likely that
  you will also have a cavity wall tie. A cavity
  wall tie sits between your internal and external
  walls within the cavity. They are typically
  installed during the construction process, with
  each tie embedded in the mortar at a consistent
  distance. A cavity wall typically has different
  properties on the interior and exterior walls.
  For example, the interior wall is usually the
  load bearing wall. What a cavity wall tie does is
  pass the stability onto the exterior wall,
  allowing the walls to stick together. You dont
  have to worry about things like slight ground
  shifting, temperature induced distance variations
  or water ingress. Cavity wall ties are designed
  to compensate for these factors and accommodate
  them should they occur.

• Why does cavity wall tie fail?
• Cavity wall tie failure is the failure of the
  cavity wall tie to hold the walls together.
  Cavity wall tie failures can occur in a variety
  of ways, and the damage they can cause to your
  property can vary from minor to severe.
• Corrosion
• Most of the wall ties that youll find in your
  propertys walls are made of steel thats not
  built to last. Most of the time, this steel is
  relatively mild, and its usually covered in
  paint or just painted before its put into a
  wall. This means the steel itself will be exposed
  to the elements, which means itll corrode and
  wear down over time.

• Construction failure
• Cavity wall ties can also fail due to poor or
  incorrect installation at the time the property
  was built. Ceiling wall ties can fail due to a
  variety of reasons, such as poor quality building
  materials, spacing is inadequate between the
  cavity wall ties, improper installation, not
  installed at the time of construction, etc.
