Wall Tie Removal Specialists Nationwide Across the UK
Worried about cracks, bulging brickwork, or loose gables? CavTie carries out wall tie surveys, wall tie removal (isolation), and wall tie replacement anywhere in the UK. Offering survey's, reports and remedial works.
What Are Wall Ties?
Wall ties are metal connectors that link the outer and inner leaves of a cavity wall so the wall behaves as one stable structure. Over time, older ties (especially pre-modern standards) can corrode or fail, which may lead to cracking and movement.
Signs Your Wall Ties Are Failing
If you notice any of the following, it’s worth getting a specialist survey:
- Horizontal cracking along mortar beds (often high level)
- Bulging / bowing brickwork
- Cracks around windows or internal cracking
- Cracks in render
- Gable movement / roofline distortion
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 Removal (Isolation)
As part of the replacement process, corroding and failing ties are removed / isolated to stop ongoing stress on the outer leaf.
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?
Most wall tie failure isn’t sudden, it’s gradual deterioration over time.
Corrosion typically occurs when older mild steel ties are exposed to moisture inside the cavity. As the metal oxidises, it expands. That expansion places pressure on surrounding mortar joints, leading to cracking and outward movement of brickwork.
The most common causes include:
- Ageing mild steel ties (common in older housing stock)
- Poor cavity drainage
- Inadequate original installation
- Low tie density in older builds
- Properties built before modern corrosion-resistant standards are particularly vulnerable.
Left untreated, expanding ties can contribute to horizontal cracking, bulging walls, and loss of structural restraint. That’s why early identification matters.
