Rat-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.

The 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

Filler 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.

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.

Frameless 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.

Rubble 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.

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
http://costford.com/Construction%20Technology.html
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
