This is for the basic information about the cost effective way for roofing.

1. FERROCEMENT
ROOF

2. DISCRIPTION
 The ferrocement roof consists panels size
1.5mtrs.x1.2mtrs. approximately and ferrocement
portal and purlins replacing AC sheets and structurals
steel trusses and purlins. Unlike AC sheet Metal, FRP
roof all the ferrocement panels are joined
monolithically. There will be no nuts and bolt
arrangement as in the case of AC sheet Metal, FRP
roofs. But ferrocement panels shall be connected to
the purlins and portal by welding and in-situ
vibrated cement matrix application. Or Ferrocement
mega tiles of size 1.5 x 1.2 mtr. or more are laid just like
Mangalore tiles with most effective interlocking
arrangement to prevent rain water entry below. There
will be least heat transfer as compared to AC sheets
etc. The space below the roof shall be neat and clean
since the steel trusses are eliminated. There will be far
better storage space below without obstruction.

3. The ferrocement roof is superior as compared to
A.C. sheets roof and metal sheets as below: -
 Ferrocement can be monolith, jointless roof
eliminating trusses and purlins nuts and bolts and joints
as in the case of AC sheet/ Metal sheets roof.
 Ferrocement roof shall transfer much less heat as
compared to AC sheet/ Metal sheets roof. It can be
fully insulated against heat transfer. Jointless
ferrocement roof prevent humidity transfer inside.
 Since structural trusses, purlins are eliminated space
there is more storage space.

4.  Since ferrocement roof is monolith, there
is no phenomenon such as cracking as
in the case of AC sheet/ Metal sheets
roof and leakage of rainwater and
corrosion of nuts and bolts, therefore,
least maintenance operations. Soffit of
ferrocement roofs is neat and clean as
compared to AC sheet/ Metal sheets
roof since there are no steel trusses or
tubular trusses.

5.  In the long run ferrocement roof are very economical.
 The performance of gutters and valleys is superior.
Because these are integral with roof.
 The life of tubular truss roof is much less in view of
earlier loss of strength due to corrosion.
 Wooden trusses purlins require replacement off and
on. In ferrocement roof, no replacement is necessary.
 Ferrocement roof is trouble free and durable for
decades.

6. USAGE
 Ferrocement structures
 Highrise buildings
 Inbuilt Ferrocement Structural Formwork
 Ferrocement scores over R.C.C.
 Ferrocement structurals score over Steel Structurals
 Ferrocement plated RCC structures
 Horizontal And Vertical Extension Of RCC Buildings
 Water StorageTanks Underground Overhead Tower

10. View of the roof from inside The
fans and lectrical fittings
attached to roof can been seen.

11. This is a complete Kiosk structure with
ferrocement foundation, walls, columns
and roofs.
Most appropriate for resorts structure and
fast food kiosks.

proofing treatment necessary.

15. This is a roof of a small structure with cast
insitu treatment. The white band all
around is also of ferrocement. The size of
the roof is 6x3x1.2 Mtr. ht. & This is inside of
the roof consisting of ferrocement portals
and purlins. All cast insitu
finish smooth. Electrical installation fixed to
the roof is visible.

16. Corroded metal roof, Detroit,
USA and Such corrosion is not
possible with Ferrocement.

17. Ferrocement roof interlocking tiles size
1.2x0.9mt. X20mm thick. Size can be
increased to 2.4 x 1.2 mtrs. x 25mm thick
or so and laid in position with new
arrangement supported by
ferrocement portal

18. Company Profile
 Incorporated in 2002, unified steel and reinforced
cement building kit manufacturer . has stayed on the
cutting edge of modern construction technology with
its patented Ferrocement aprovides building solutions
worldwide, from low-cost housing to luxury tourist villas.
Projects include disaster resistant structures, such as
schools, daycare centers, commercial & hospitality
complexes, and agro-industrial facilities. Worldwide
technology services include global internet marketing
of am-cor Kits through its online store, Ferrocement
structural engineering & project design, and hands-on
site instruction showing builders how to assemble and
finish am-cor building shell kits.m-cor Construction
System

19. WHY SHOULD WE USE IT?
 Ferrocement is able to offer superior services and
building construction at lower cost through a
combination of advanced technology and decades
of experience. The ferrocement construction system is
a proprietary technology based on patented panel
designs by architect & inventor Angus W. Macdonald.
Using advanced, specialized 3D modeling and
engineering software,and. quickly estimates
construction cost and publishes detailed illustrated
manuals explaining manufacturing, field assembly and
finishing techniques.

20. GOAL

21. Green and sustainable
Development from ferrocement.
 New green and sustainable Ferrocement panel
factory as a model production facility. Production
machinery, climate control, hot water and other
services will be solar powered, reducing the carbon
footprint of building panels and completed building
shells. The factory, in Culpeper, VA, is centrally located
on the US Eastern Seaboard, near the ports of Norfolk,
Richmond, and Baltimore. We believe that through a
combination of global thinking, environmental
awareness, and construction innovation, people can
inexpensively build green, sustainable, and beautiful
buildings that will withstand natural disasters, rising
energy prices, and the test of time.
