What are cavity wall ties and why are they used?

The purpose of a cavity construction is to prevent water penetration unlike the traditional solid nine inch masonry wall by splitting it into two leaves of 4½ inch brick, linked with metal ties. Cavity wall ties are laid out in a uniform spacing pattern: a diamond formation with ties at 900mm centres in courses set 450mm apart. At door and window openings the spacing is reduced to 300mm vertically.

The most common wall tie used is mild steel and the commonest manufactured forms are the fishtail or vertical twist ties (either galvanised or bitumen coated) and the galvanised butterfly wire tie.

All mild-steel ties are susceptible to corrosion over time. Because the service life of the masonry is much longer than that of the mild steel at some point in its life the wall may need replacement of the wall ties.

Cavity Wall Tie Failure

Problems with corroded wall ties have become extremely common to properties in the UK. The corrosion of wall ties can seriously affect the structure of a building. Over time mild steel wall ties expand and corrode forcing apart the bricks above and below the bed joints in which the cavity wall ties are laid (this can be up to 7 times it’s original size), producing a pattern of horizontal cracks coinciding with the tie position. It is important to treat the symptoms of wall tie failure as in some cases walls will bow and could collapse due to external forces.
