Brick wall thickness

The convention for describing the thickness of a wall is relative to the length of a brick so goes like this. It may seem counterintuitive but as its long established deviating from it will lead to confusion.

A ½ brick wall which was sometimes called a 4 inch wall is:

A half brick thick brick wallA half brick thick brick wall

A 1 brick wall which was sometimes called a 9 inch wall:

 A one brick thick brick wallA one brick thick brick wall

A 1½ brick wall which was sometimes called a 14 inch wall:

 A one and half brick thick brick wallA one and half brick thick brick wall

And so on, so the next is a 2 brick wall (18 inch wall) and then a 2½ brick wall (22 inch wall).

Brickwork

This is anything constructed from bricks which are normally fired clay, yes we are really still building from mud! The small size of the individual bricks makes brickwork and incredibly flexible building material to make garden structures out of.

A few points to note:

  • The thickness of a brick wall is described relative to the bricks length so the wide of a wall goes up in half brick steps starting with a ½ brick.
  • The mortar between the bricks is there to keep the bricks apart and stop them wobbling, it DOES NOT STICK the bricks together! In fact to an engineer brickwork has no tensile strength, that is to say it has little or no strength when being pulled apart.
  • Most bricks have little resistance to frost when wet so unless engineering bricks are being used things like retaining walls will need to have the brickwork protected from moisture.

Bond

This is a pattern that tied individual components together both structurally and visually and comes in a variety of styles including stretcher, Flemish, English, English Garden Wall, Herringbone and Random.
