Wall Tie Isolation
Nationwide Corroded existing wall ties may need isolation as part of an agreed remedial repair scheme. CavTie assesses the ties and surrounding masonry through a wall tie survey, then explains the recommended replacement, isolation and repair work.
When Is Wall Tie Isolation Needed?
Wall tie isolation may be recommended when corroded existing ties are contributing to cracking or damage in the surrounding masonry. A wall tie survey helps establish the condition of the ties and the appropriate remedial work.
Isolation is assessed alongside replacement ties and any necessary masonry repairs. Cracking alone does not confirm wall tie failure, so the repair scope should follow the survey findings.
What Does Wall Tie Isolation Involve?
Wall tie isolation separates the affected part of an existing tie from the surrounding masonry to reduce the risk of further damage from corrosion expansion. The appropriate method depends on the tie type, wall construction and survey findings.
Where replacement ties are required, they form part of the agreed repair scheme. Isolation is not a substitute for providing suitable ties between the inner and outer leaves of the cavity wall.

Why a Survey Matters
Corrosion does not automatically mean that a wall tie has failed. Advanced corrosion can cause expansion that damages mortar joints or surrounding masonry, while insufficient ties or poor distribution can affect the wall’s restraint.
A survey helps distinguish these issues and establish what work is appropriate. CavTie provides findings and recommendations so you can make an informed decision about replacement ties, isolation and localised masonry repairs.
