After many years of research, a considered response was required to select the most suitable solution to fix the damaged wall. This led to three options being put forward:
Option 1: Localised repair to the cracked and displaced brickwork
In terms of construction, this would be the swiftest project and works could be undertaken with minimal disturbance. However, it would be a challenge to source new bricks to exactly match the existing wall.
This option is the lowest cost but does not address the causes of the cracking. There would also be a high probability of a patchy appearance to the wall.
Option 2: Brick slip facing wall
This option requires the facing wall to be completely removed, exposing the structural brickwork behind. This brickwork would be cut back to provide a suitable surface to fix a profiled, rigid polystyrene base layer. This would then be hidden by 20-30mm thick brick slips which are bonded to the polystyrene and pointed with mortar.
The difficulty with this option is obtaining listed building consent. This is also the most expensive option and could lead to future high maintenance costs.
Option 3: Replace the whole wall
The entire facing wall would be completely removed and reconstructed with either new or reclaimed bricks. This would ensure a uniform finish and address the cause of the cracking.
After careful consideration, option 3 was selected to be carried forward. Find out more about it next time.
