only frost-proof quality bricks are suitable and that recessed or
raked out joints which could retain water must be avoided.
Typical external wall base †
Corbel † a projecting
feature at higher levels of
a building. This may be
created by using plinth
bricks laid upside down
with header and stretcher
formats maintaining bond.
For structural integrity,
the amount of projection
(P) must not exceed one
third of the overall wall
thickness (T). Some other
types of corbel are shown
on the next page.
