While it is desirable for the length of a wall to be designed to brick lengths, sometimes it will have to be of a length that does not ‘work bricks’, meaning that it will not be possible to lay full stretchers and/or headers. In such cases, cut bricks will have to be introduced to make the bond work to the length of wall required.
With this in mind, it is very important first to set-out a wall by laying bricks out with no mortar. This is called ‘dry bonding’ and will identify what adjustments need to made to the bonding arrangement. Sometimes it will be necessary only to adjust the width of the cross-joints, however the tolerance
is only +/- 3mm so joints can be a minimum of 7mm and a maximum of 13mm.
