5 ways to identify wall tie failure

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