Brick Laying

A good bricklayer carefully plans their work prior to laying. This involves:

  • Carefully reading ALL building consent documents and familiarising themselves with any standard cited in the documents before starting
  • Checking that the substrate has been properly prepared and sealed where required,
  • Calculating how many bricks are going to be required (and ensuring that factors such as mortar thickness are taken into account),
  • Checking the bricks supplied are correct as per the building consent and contract,
  • Checking that there are no obvious issues/defects with the brick pallets provided,
  • Checking that all pallets display the same batch number
  • Identifying what cuts may be required.

Bricks should be laid to a straight line which generally involves running a string line at both ends of the wall. Bricks should be buttered to form perpends (“perps”).
NZS4210:2001 sets out the following tolerances for brick veneers walls:

BRICK BLENDING
Bricks are natural products that are subject to colour variance between batches. ‘Blending’ is the process used to vary brick pallets as they are laid as a means of avoiding any unwanted patterns caused by a variance.

Master Brick & Blocklayers recommends that bricklayers select bricks and blend vertically from at least three pallets in order to achieve an adequate colour mix.

A bricklayer should also regularly check the veneer while laying from a viewing distance of 6.1m for obvious pockets of colour forming that may be unacceptable.
