Types Brick as masonry

Bond is a pattern in which the bricks / Stones / AAC blocks/concrete blocks are laid as walls, paving to provide the strength, durability, uniformity and good look. There are many types of bonds based on the look, method of installation and structural considerations.

Mainly or most widely used masonry bonds are:

     1.     Stretcher Bond / Running Bond

     2.     Header Bond

     3.     English Bond

     4.     Flemish Bond

a.     Single Flemish Bond

b.     Double Flemish Bond

    5.     Dutch Bond

    6.     Common Bond / American Bond

    7.     Facing Bond

    8.     Rat Trap Bond

    9.     Edge bond (Silverlock’s bond or Soldier’s course)

   10.  Raking bond:

a.     Diagonal Bond

b.     Herring-bone bond

   11.  Zigzag bond

   12.  Garden wall bond

a.     English Garden wall bond

b.     Flemish Garden wall bond

   13.  Sussex bond

   14.  Dearne’s bond

   15.  Stack Bond

    Let see the pattern of each bond:

1.     Stretcher Bond / Running Bond:

     2.     Header Bond

     3.     English Bond

     4.     Flemish Bond

a.     Single Flemish Bond

b.     Double Flemish Bond

    5.     Dutch Bond

    6.     Common Bond / American Bond

    7.     Facing Bond

    8.     Rat Trap Bond

    9.     Edge bond (Silverlock’s bond or Soldier’s course)

   10.  Raking bond:

a.     Diagonal Bond

b.     Herring-bone bond

   11.  Zigzag bond

   12.  Garden wall bond

a.     English Garden wall bond

b.     Flemish Garden wall bond

   13.  Sussex bond

   14.  Dearne’s bond

   15.  Stack Bond 

    Cutting the blocks / bricks:

     

Other than building wall, especially bricks were used for waterproofing material normally said as "Brick Bat Coba". Brickbat waterproofing is one of the oldest methods of waterproofing, and with new modern waterproofing products available in the market, brickbat waterproofing has become absolute these days.

General specificaiton of brick bat coba is: 

Application of Slurry under Base coat: The bonding slurry (prepared using E 135, water and cement in ratio of 1:1:3) shall be applied over the dampened surface with brushes including the joints between the floor slab and the parapet wall, holes on the surfaces and joints of pipes in masonry/concrete. The application of the slurry should continue up to a height of 300 mm over the adjacent wall. Bonding slurry should also be applied up to a height of 150 mm over pipe projection etc.
Laying Base coat: Install 25mm thick mortar (prepared using CM 1:4 admixed with E 160 at a dosage of 200 ml per bag of 50 Kg cement), over the wet / tacky bonding slurry. Packing all corners and pipe penetrations. The application of the mortar shall be continued up to a height of 300 mm over the adjacent walls.
Placing of Brick bat: Brick bats of size 40 (Or lesser depending the minimum thickness of Brick Bat Coba) to 75mm thick shall be placed over the mortar bed by hand packing having minimum 15mm thick mortar below the brick bats and suitable gaps in between. Only fully burnt bricks shall be used and the brick bats shall be well soaked before laying. Application of another layer of bonding slurry after curing of the above surface for a minimum period of 24 hours. Then filling the gaps between the brick bats with mortar.
Laying Finishing Layer: Immediately on applying the mortar is still green, a 20mm thick layer of mortar, without leaving any joints shall be applied over the entire surface including the coving. The surface shall be neatly finished with bonding slurry and finished smooth with steel trowel. The surface shall have proper slope towards the drain out let pipe. The finished surface shall be allowed to dry for a while till a string mark can easily be made on the surface, when 300mm x 300 mm square marks shall be made over the entire surface.
Curing: The entire surface shall be flooded with water by making bunds with weak cement mortar, water shall be made to remain on the surface for a minimum period of two weeks during which it can be observed if there are any leakage or not.

    

Advantages of brick bat coba:

1. Can be done by used / broken bricks.

2. Can be left exposed for foot traffic.

3. Option to provide slope.

Disadvantages of brick bat coba:

1. Increase in load because of use of brick, sand, cement at higher thickness.

2. Consumes time, manpower.

3. Need skilled man-power.

4. Possible mistakes in the workmen ship.

5. Rigid, not flexible, hold water in it.

6. Thermally, not stable and non-UV

7. Verry difficult to repair, if leakage found.

Because of modern construction chemicals, this has been replaced by liquid-applied coating and sheet applied membranes. But, still, some prefer to use coba system by adding construction chemicals like integral / crystalline, etc admixtures including replacing the brick with lightweight aggregates like thermocol.
