Why Wall Ties Matter in Cavity Wall Construction

Wall ties might be small, but they play a big role in keeping your property safe and stable—especially in homes with cavity walls. Here’s why they’re essential:

• Structural Support: Wall ties join the inner and outer layers (or ‘leaves’) of a cavity wall, helping the wall act as one solid structure rather than two separate parts.

• Even Load Sharing: They spread pressure evenly across both leaves, preventing bulging or movement due to wind, temperature changes, or settling.

• Fire Protection: In a fire, ties help hold the outer wall leaf in place, reducing the risk of collapse.

• Damp Defence: Many wall ties feature a drip design to stop water from moving across the cavity, helping prevent internal damp.

• Tailored to Conditions: There are different wall tie types to suit building size, location (like coastal areas), and exposure to wind.

Takeaway: Whether you’re buying, renovating, or selling a property, checking the condition of wall ties is a smart move—especially in older buildings where corrosion can be an issue.
