Wall ties are also popular as brick ties. They are essential for cavity wall buildings and connect the inner and outer leaves of a building. It provides stability to the building’s structure. They are generally made from stainless steel nowadays because of their corrosion-resistant properties. But the older buildings may be built using other materials. Since the early 20th century, wall ties have become standard practice in the UK. We suggest hiring a good company for wall ties replacement in Hampshire.
A Quick Guide To Wall Ties and Their Functions
What are Wall Ties?
These are metal strips or bars that span your wall’s entire cavity. They are most commonly used to join the two parts of a wall. This allows them to act as a single solid unit.
