Wall Ties and Warning Signs
Wall ties connect the inner and outer leaves of a cavity wall. Older mild-steel ties can deteriorate depending on their coating, exposure and conditions within the cavity. Corrosion does not automatically mean failure.
Horizontal cracks along mortar joints, bulging brickwork, cracks around windows or doors, cracked render and movement at gable ends may justify a wall tie survey. These signs can have other causes, so an inspection is needed before recommending repair work.
Our Services
Wall Tie Surveys
A specialised inspection to confirm whether wall ties are present, where they sit, and what condition they’re in. Clear findings, detailed report, and recommended next steps.
Wall Tie Isolation
Where recommended following a survey, defective existing ties are isolated from the surrounding masonry as part of the agreed remedial scheme. Replacement ties and localised repairs are assessed alongside isolation.
Wall Tie Replacement
Following a survey and report, when wall tie replacement is required, we install new stainless steel remedial wall ties into the cavity wall in a calculated pattern designed to stabilise the outer leaf.
What Causes Wall Ties to Corrode?
Older mild-steel wall ties can corrode when moisture reaches the metal and the protective coating deteriorates. The rate and extent depend on the tie type, coating, exposure and conditions within the cavity. Wet or poorly performing cavity insulation can contribute to deterioration.
Advanced corrosion may cause expansion that damages mortar joints or brickwork. The number and distribution of ties also affect restraint, but low tie density is a separate defect rather than a cause of corrosion.
A wall tie survey identifies whether replacement ties, isolation or localised masonry repairs are appropriate.
