This slide share shows you how bonding works in terms of distributing the loads and the types of bonds commonly used

1. Basic Brickwork Bonds
BONDING is the term given to the various
recognised arrangements of brickwork
walling.
These bond patterns are essential for any
wall which is intended to carry HEAVY
LOADS and they prevent as far as possible,
any structural failure.

2. For this to be affective the bonding must
distribute the loading evenly throughout the
length of the wall, so that each part of the
wall carries a small amount of the load.
If, on the other hand the load is not
distributed but localised to certain portions
of the wall, then this may cause uneven
settlement and cracking.

4. The bonding of brickwork however, is not
confined to strength requirements only.
Very often a certain bond is introduced for its
pleasing appearance , along with another
bond to give a decorative appearance.

5. TYPES OF BRICKWORK BONDS
There are a large
number of bonding
arrangements, here
are some of the
more common ones
in use.
STRETCHER BOND
ENGLISH BOND
FLEMISH BOND
ENGLISH GARDEN
WALL BOND
HEADER BOND

6. STRETCHER BOND
Stretcher Bond - Consists of all bricks laid
as stretchers on every course with the
courses laid half-bond to each other.
This is effected in a plain wall with stopped
ends by introducing a half-bat as a starting
brick to alternate courses, and is usually
only used in walls of a half brick thickness.
Here is the bonding progression laying all of
the first course, racking the corners up and
then proceeding to run inn.

Half Bats or Headers
Racking back

8. TASK 1
On the note-paper provided,
using a pencil and ruler draw in
the bonding arrangements for a
stretcher bond wall.
Note: There are Four lines to
each Stretcher.

10. ENGLISH BOND
English bond- has alternate courses of headers
and stretchers, with a closer placed next to the quoin
header to form a lap,0r half bond.
The first course is established ,and then corners are
racked back as soon as possible to enable you to
run in the rest of the wall.
In the next slide we will see the technique for
construction of an English bond wall.

14. FLEMISH BOND
Flemish bond- consists of alternate courses of
headers and stretchers with the headers of one
course being placed centrally over the stretcher in
the course below.
A closer is placed next to the quoin header to form
the lap or half bond.
Forming a Flemish bond wall racking back corners,
and running in main wall.

bonding arrangements for a

17. FLEMISH BOND

18. ENGLISH GARDEN WALL
BOND
English Garden Wall Bond- Sometimes
called Sussex bond, consists of three or sometimes
five courses of stretchers to one course of headers;
the stretcher course being laid half bond to each
other.
The bonding arrangement can be seen in the
following slide establishing the first course as usual,
racking back the corners , and the proceeding to run
in using a line.

22. HEADER BOND
Header Bond- Is satisfactory for walls one brick
thick and consists of all headers, with the bond
being formed by three-quarter bats at the quoin.
This can be used in footing courses, or walling that
is curved.
Bonding is as usual, lay first course, rack corners
back as soon as possible and proceed to run in.
