In our ‘spot the defect’ this week we focus on the traditional art of laying brick and block.

What do you think the defects are in the following picture?

Did you get it right?

The photo shows the following issues;

  1. The bonding is inconsistent causing vertical joints to coincide on consecutive courses.
  2. The correct length and type of wall ties have not been used to ensure they are properly bedded into each leaf of masonry (view the table in our article ‘How to use cavity wall ties correctly to see length of wall tie required for a specific cavity width).

For more information on the best practice when laying brick and block you can download a copy of our checklist for building masonry walls.

Alternatively you can refer to Chapter 1.1 of our Technical Manual.
