Do You Have Cracks in Your Walls?
White Rock Property Care are trusted specialists in cavity wall tie surveys and replacements in Swansea and across South Wales. If you’re seeing signs of cracking, wall movement or render damage, the issue may be due to corroded or failing cavity wall ties — a common but serious structural concern in older properties.
What Are Cavity Wall Ties and Why Are They Important?
Cavity wall ties are metal connectors used to join the inner and outer layers (or “leaves”) of cavity walls. They have been a standard part of UK housebuilding since the 1930s, helping to stabilise walls and improve insulation. Originally made of bitumen-coated or zinc-galvanised steel, these ties were never designed to last indefinitely.
Over time, they can corrode, expand, and lose their strength — leading to cracks, instability, and long-term structural risk if left untreated.
How Do I Know If My Wall Ties Are Failing?
Common signs of cavity wall tie failure include:
Stepped cracks following the mortar lines in brickwork
Horizontal cracks in render or masonry
Bulging or movement in external walls
Loose bricks or degraded pointing
If you're seeing any of these issues in your Swansea or South Wales property, it's time to arrange a professional wall tie survey.
What Does a Cavity Wall Tie Survey Involve?
At White Rock Property Care, we use advanced inspection tools and experienced surveyors to assess the condition of your cavity wall ties. This includes:
Endoscopic inspection
Corrosion assessment
Structural movement checks
Wall tie location and spacing verification
Our team adheres to industry guidelines to ensure the correct specification of tie type and replacement method.
How Are Wall Ties Replaced?
We follow a proven process to replace or remediate failing cavity wall ties:
Isolate corroded or failed ties
Drill through the external wall to install new stainless steel, non-corrosive ties
Install new ties to precise locations to meet current building regulations
Perform random ‘pull out’ testing during the process to confirm secure fixings
All work is carried out by our in-house technicians – no subcontractors – ensuring total control and quality.
Do You Need Wall Ties for a New Extension or Wall?
Yes – we also install cavity wall ties where new walls meet existing structures, ensuring long-term structural performance. This is especially important during extensions, conversions or renovations.
