The team undertook a cavity wall ties and helibars installation job, so let’s get into why these are important, and what CavClear can do to help your home. Our recent survey showed the signs of failing cavity wall ties, leading to recommendations for heli bars and wall tie replacement, let’s explore what it means.
Understanding Cavity Wall Ties
Cavity Wall Ties serve as essential components in the structural integrity of buildings. These metal rods or strips connect the inner and outer leaves of a cavity wall, reinforcing stability and support.Wall ties are essential metal components crucial to the structural integrity of your home.
Identifying Cavity Wall Tie Failure
This deterioration can be attributed to various factors, with prolonged corrosion being the most common culprit. Made of metal or metal alloys, cavity wall ties are susceptible to rusting and corrosion when exposed to water or dampness within the cavity. While rusting is a natural process for metal, environmental factors such as flooding, heavy rainfall, or leaks can accelerate this process.
Failure of cavity wall ties manifests as compromised structural stability, often evidenced by staggered cracking along the walls. This deterioration can escalate to wall collapse if left unaddressed. Recognising these warning signs is crucial for timely intervention and maintenance.
What’s a HeliBar?
HeliBars are a type of retrofit masonry reinforcement used to stabilise and strengthen structures. They are often used in situations where traditional methods of reinforcement, such as cavity wall ties, are insufficient or impractical.
HeliBars work by distributing forces across the structure, reinforcing it against cracking, bowing, or other forms of structural failure. The helical design of the bars allows them to bond securely, providing effective reinforcement without significantly altering the appearance of the structure.
In the case of the job completed by our team, they’ve been used promote the stability of a recent extension that has been built, that is coming away from the main building.
Can CavClear help?
Don’t wait until structural issues escalate. If you suspect cavity wall tie failure in your property, reach out to book a wall tie survey. Our surveys come with a full report and recommendations, with the option to continue with remedial works such as Wall Tie Replacement.
