Wall ties may not be the first thing that comes to mind when thinking about a building's structural integrity, but they are critical to guaranteeing stability and safety.
So, what exactly are wall ties? In simple words, wall ties are small but powerful components used in masonry buildings to connect the exterior brick or block veneer to the internal load-bearing walls. They guarantee that both levels of a wall function as one structural unit.
So, how exactly do wall ties work?
There are different types of wall ties and they all work differently.
Cavity Wall Ties
These are the most common type, used to tie the outer brickwork to the inner blockwork in cavity walls. They span the cavity between the two walls and are designed to allow water to drain away, preventing moisture from penetrating the inner wall.
Veneer Wall Ties
Used in veneer walls, these ties connect a single non-structural outer layer of masonry to a structural backing wall. They are essential in modern construction where aesthetics are combined with functionality.
Partition Wall Ties
These ties are used in internal partition walls to connect different sections of masonry. They ensure that the walls are stable and can bear loads appropriately.
Mechanical Wall Ties
Mechanical ties, commonly known as 'expandable' or 'wire' ties, were extensively employed in earlier masonry structures. They possess expanding mechanisms at both ends, providing a firm grip when inserted into a drilled hole.
Resin Bonded Wall Ties
Resin bonded, or chemical wall ties, are usually made from stainless steel. They are inserted into drilled holes filled with polyester resin, forming a strong bond as the resin cures.
Remedial Wall Ties
Remedial or retrofit ties are used in existing walls, especially when the original wall ties corrode or fail. These are designed for easy insertion into the wall, and their ends expand or twist to secure themselves in place.
