Storms and wall tie failure

Frequent storms and the impact on your property

One thing we are seeing a lot more of these days is the frequent storms hitting the UK.

Have you ever thought about the impact these storms are having on your property?

Storms can significantly impact the structural integrity of buildings, particularly older properties with cavity walls. One of the most common storm-related issues is wall tie failure, which can compromise the stability and safety of external walls. Every year, we have seen the devastating impact these storms cause on buildings and people’s homes. On most occasions, the owners were aware of certain signs of wall tie failure, but unfortunately, they chose not to have them investigated by a professional.

How storms contribute to wall tie failure

1. Increased wind pressure 

During storms, strong winds can exert abnormal pressure on the outer wall. If wall ties are corroded or insufficient, this pressure can cause walls to bulge, crack, or even collapse.

2. Water Ingress

Heavy rain driven by wind can penetrate the outter wall, accelerating corrosion in older stell wall ties. Rust expands and can crack surrounding mortar, weakening the wall structure.

3. Temperture Fluctuations

Sudden changes in temperture during storms can cause materials to expand and contract, placing stress on already compromised wall ties and leading to cracking or movement in the wall.

4. Loose or damaged cladding/ pointing 

Storms often damage external finishes, allowing more moisture to seep in. This exposure increases the risk of wall tie degradation.

 

Signs of wall tie failure (Often worsened after a storm)                                                                  

  • Horizontal cracks in the mortar joints
  • Bulging or bowing brickwork
  • Seperation between walls and window/ door frames
  • Cracked render or damp patches internally
  • Noises during strong winds (Creaking or movement)
