Wall Tie Replacement

Cavity walls incorporating metal ties have been used since the 19th century, and are particularly common in dwellings built in the early part of the 20th century.

They are distinguished by the pattern or ‘bond’ of the bricks: if the wall’s bricks are laid with the long edges facing you, the wall is a cavity wall. If however the wall is rendered or plastered and the bond cannot be seen, the simplest way to test its construction is to drill a small hole through the outer face to a depth of around 5-inches. If no cavity is found, the wall is probably solid. This can be further confirmed by checking the wall thickness — a cavity wall measures 10 or 11-inches — at door openings or window reveals.

Cavity construction’s ability to improve the weather resistance and stability of the traditional 9-inch masonry wall has seen this form of engineering become the standard form of construction for both houses and buildings of a similar scale since 1950.

Wall ties are susceptible to corrosion and can need replacing for a whole host of reason. Signs to look out for include:

  • Horizontal cracking at regular intervals in external mortar joints
  • Outward bulging of the wall
  • The lifting of roof edges
  • Internal cracks
