Our most recent ‘spot the defect’ challenge focuses on masonry leafs.

Take a look at the below image. Can you spot what’s wrong?

What did you spot?

The photo shows the following issues:

  • A horizontal chase to accommodate the piping was found to be more than 30mm deep, at approximately 600mm above the floor level. This exceeded the maximum allowed by nearly double.
  • Cracking in the block work was also observed above and below the chase.

Further information can be found in Chapter 9 of the LABC Warranty Technical Manual. We also have the following articles you may be interested in;
