Brick quantities for various bonds

[Richard]

page 13 it shows various bonds. Every one except one is a brick thick. Bottom right gives quantities of bricks for one square meter of brickwork, a half brick thick.

Question: Why have they quoted quantities for a half brick thick, when I presume, in practice, nobody would build those bonds a half brick thick, (except stretcher bond)?

Would it not have been better to give figures for a brick thick wall? Thanks.

A full brick would be a 9" thick wall as built pre cavities. A half brick is 4.5" as per a single leaf of a cavity wall.

Its easy enough to remember 50 bricks per sq yard and double it for a double wall.

(all sizes tend to be metric now and are a little bit smaller)
