5 ways to identify wall tie failure
- Horizontal cracking – at regular intervals in external mortar joints
- Outward bulging of the wall – joints widen causing the wall to deflect outwards, often around window frames
- The lifting of roof edges – At gables the growth of brickwork can cause a noticable ‘pagoda’ effect
- Internal cracks – vertical cracks may be found at internal wall junctions & horizontal cracks appear at internal wall and ceiling joints
- Cracks to render coats
