BRICK coNStructionRat-trap Bond

This double-wall technique

uses bricks on edge with a cross brick

between each and produces a 9-inch thick

wall with an insulating air cavity in

between. Surprisingly, this technique

reduces the number of bricks required by

25%, thereby reducing material used,

including mortar (1:8 mix), and overall

cost. Rat-trap technique is equal to the

strength of a solid 9-inch wall in either

Flemish or English bond.

BRICK coNStructionThe main highlights of Rat -trap bond

masonry.

• Quality of construction will be

improved automatically by using

selected bricks, which also gives

uniform surface on both sides of wall.

• The appearance will be much

better as it gives an exposed brick

finish.

• The joints are always uniform in

size and shape so the plastering can be

avoided, if required a pointing will

give a better aesthetic finish.

• The hollow spaces created by the

Rat -trap bond masonry improves the

thermal insulation up to some extent.

• Electrical conduits can be

accommodated in the hollow portion

to avoid cutting/ chasing the walls.

• By avoiding unnecessary

plastering, we can save up to 10% of

the brickwork cost.

Creative bricklaying is a defining

visual characteristic of COSTFORD buildings with

varied arrangements providing natural

ventilation instead of costly and environmentally

damaging air conditioning. Jali walls also provide

privacy, security, cost reduction in windows

needed, and most dramatically aesthetic

appeal.

Jalli Wall

A jali or jaali,is the term for a

perforated stone or latticed screen, usually with an

ornamental pattern constructed through the use of

calligraphy and geometry. This form of

architectural decoration is found in Indian

architecture, Indo-Islamic Architecture and Islamic

Architecture.

Early jali work was built by carving

into stone, while later by the Mughals who

employed the technique of inlay, using marble and

semi-precious stones

BRICK coNStructionFiller Slab

Lightweight, inexpensive materials

such as lowgrade Mangalore tiles, bricks, coconut

shells, glass bottles, are used as filler materials in

filler slabs to replace the redundant concrete in

tension zones.

These materials are laid in the grids of

steel reinforcement rods (6mm or 8mm dia.), and

concreting is done over them. The concrete mix

used is 1:2:4. The grid size depends upon the

design, span, and the material used. For Mangalore

tiles (size 23cm by 40cm), the grid size is 33cm by

50cm. The slab thickness is 10 centimeters.


BRICK coNStruction

This technique also reduces the

unwanted dead load of roofing. Compared

to other roofing systems. The strength and

durability of filler slabs are same as the

conventional RCC slabs.

It is thermally comfortable and

has no health hazards. Galvanized iron and

asbestos cement sheet roofs dissipate too

much heat and are difficult to live under.

Also, asbestos cement sheets are long

associated with diseases such as lung

cancer, hence must be avoided.


BRICK coNStructionFrameless Doors and Windows

Door and window frames are not

actually required. They are responsible for almost

half the cost of timber used. Avoiding frames

considerably reduces the cost of timber.

Door planks are screwed together with

strap iron hinges to form doors, and this can be

carried by holdfast fittings carried into the wall. The

simplest and most cost-effective door can be made of

vertical planks held together with horizontal or

diagonal battens.

The simplest frameless window consists

of a vertical plank (9” wide) set into two holes, one

at the top and one at the bottom. This forms a simple

pivotal window. Wide span windows can be partially

framed and fixed to walls or can have rows of

pivotal planks.

BRICK coNStructionRubble Masonry

Rubble masonry is rough,

unhewn building stone set in mortar, but not

laid in regular courses. It faced with

unit masonry such as brick or cut stone.

Random rubble masonry is

extensively used as foundation at places

where stones are readily available. An 18”

(45 cm) foundation base is adequate for

most soils and single or double storey

buildings. Depth and size may vary with the

addition of number of floors. In case of

weak soil, the trench can be widened (50-

60cm) and the bottom can be laid with

concrete (1:2:4) followed by a 30-35cm

wall.

BRICK coNStruction

Proper joints (dovetail) must be

provided for stronger bonds as in the case of

any other masonry works. Stones must be large

in size and the gaps between stones must be

filled with smaller stones for proper bonding

and stability


The trench is typically dug with a

backhoe bucket several inches below frost

depth, and sloped to daylight (or a dry well) for

drainage.

This type of foundation is unique in

that it provides structural bearing as well as

water drainage in one system. The result is a

resource-efficient, high quality, low cost

foundation system
