type of bonding for garden and cavity extension walls
 

hello, can someone please help...

1) for an external cavity wall please rank these by strength/durability,
strongest first.

a) english
b) stretcher
c) header
d) flemish
e) flemish garden wall
f) english garden wall

If I want a 3 story extension will any of them be particularly well suited
or badly suited.

Unless you have a particular reason for spending twice as much on the labour and
extra wastage of facing bricks making snapped headers to create a different
bond, I would do what everybody else does and build the cavity wall in stretcher
bond.


2) for a Garden Wall please do the same.

b) stretcher
c) header
d) flemish
e) flemish garden wall
f) english garden wall

If the wall is ½B thick (102mm) Stretcher Bond is the only choice unless you
want to try to make the wall appear thicker. If it is solid 1B (215mm) or more
thick, I would go:

d, a, e, f, b, c

There's not too much to choose between English & Flemish on strength and
durability, it's more important to match up to what's there already. Stretcher
Bond is only for ½B 102mm thick walls and a 225mm wall built of it would
effectively be 2 No ½B walls built together without a tie, so it would be less
stable than English or Flemish. Header Bond is the least stable and ugly, and
only used on curved work when absolutely necessary.

I would disagree slightly. On the basis that a garden wall is to retain
something then it needs to the 1B thick. English bond is by far the stronger
bond.

I would therefore go for -

a) english
d) flemish
f) english garden wall
e) flemish garden wall
c) header
b) stretcher

In the end it will very much depend on what you want it for, to retain the
house, flower beds, height, ground conditions, traffic nearby etc.

In the extreme you might want a concrete / blok wall and then faced with
BWK.

Yes, true, but I was thinking about boundary walls, not retaining walls.

English bond is by far the stronger

Aha - the age-old argument! I remember a tea break on site once when two
brickies were arguing over this and it ended in fisticuffs. The one supporting
English Bond thought the other was being unpatriotic! :o)
