types of Flooring in construction
1.
2. THE purpose of floor is to
provide a leveled surface
capable of supporting the
occupants of a building
furniture equipment and
sometimes partition
Properties:
• Strength and stability
• Fire resistant
• Damp resistant
• Thermal insulation
• Sound resistant
5. For cheap construction
commonly provided in warehouses, stores , godowns or in
places where heavy article are stored
Well burnt bricks of uniform shape
Laid either on edge or in herring bone fashion or at right angles
or any other good looking fashion
Method of preparing the base course varies from base to base
MERITS
1. it is durable and sufficiently hard.
2. it is cheaper than cement concrete.
3. it is non slippery.
4. it is easily repairable.
6. Subgrade is compacted properly to the desired level then 75mm thick
layer of sand is spread over this course of brick course laid flat in the
mortar is built this forms the base course over which the brick flooring is
laid in 12 mm thick bed of cement or lime mortar in desired pattern
Second method : 10-15mm thick layer of lean cement concrete is laid
over the prepared subgrade. This forms the base course over which
bricks are laid on 12mm thick mortar bed .
the earth filling under floor is well compacted and thereafter 10-15 cm
thick layer of cement or lime concrete is laid over the entire area of floor
called subgrade.
the floor is laid directly over the subgrade. the slope required to be given
to the floor to care of the floor washing etc.
prior to use the bricks should be properly soaked and wetted in water.
the bricks are laid on edge on 12mm thick mortar bed in such a manner
that all the joints are full of mortar,
7. Characteristics:
Used in residential, commercial and industrial buildings
It is cheap, durable and easy to construct.
Free from corrosion
Hardens with age
Porous and has tendency to shrink
It has two components –base concrete and topping or
wearing surface.
Method:
Monolithically
Non monolithically
8. • Topping is laid immediately (1-4hours ) after the base
ADVANTAGES:
• Good bonding between two compositions
• Topping with smaller thickness 25mm
DISADVANTAGES:
• Topping damaged due to subsequent process
• Hair cracks
• Work progress is slow
9. • Topping is done after hardening of the base.
• Cleaning and cuing of base is done then base is
rubbed with wire brush
• Topping laid in rectangular or square pannels by use
of glass or plain asbestos strips.
• Panel size : 1X1m , 2X2m, 1X2m
• Topping ratio :- 1:2:4(cement concrete) upto 40mm
thickness ( aggregate size 20 mm )
• Alternate panels are laid first
• Concrete is spread evenly with floors.
• Cream of concrete comes at the top.
• Other alternate layers are laid after 72 hours
• Protect from sun rainfall and other damages for 12-20
hours
• Surface is cured for 7-14days
10. • less cracks
• work progress is fast
• Have to wait for hardening of base
concrete.

22. for laying marble for flooring, it is recommend to use
white cement, which gives the marble a highly elegant
and attractive finish which is heavy, hard, durable and
dust-free.
marble possesses greater reflectance and the crystalline
structure of polished marble gives it a bright lusture.
23. The marble should be laid in white or coloured mortar,
depending on the colour of the marble, made with a
good white cement over a damp-proof membrane.
This ensures true reflection and retains the sheen of the
marble.
25. 1.Before laying the marble tiles, make sure that all tiles
are of regular shape, i.e. for rectangular, square,
hexagonal shape of tiles, the diagonals must be of
exactly the same size for the same size of tile because
a slight difference in edges and corners may disturb the
flooring pattern.
2.First of all, for laying the tiles, prepare the base mortar
consisting of OPC and fine aggregate (Bajri) in 1:5 to
1:6 proportion. The mortar should have a low water.
26. 3.Minimum thickness recommend for the mortar is 25mm
4.Fix the marble tiles, temporarily with the base mortar in a
single or double row as per your design pattern by
pressing it over the mortar with the help of a wooden
handle of the hammer or some other wooden piece to
get it in the required level.
5.After fixing this pattern, for one or two rows of tiles,
remove the tiles and put them again after
spreading Cement slurry (cement mixes with water in
2:1 ratio) over the base mortar. This procedure is to be
followed for each tile, one by one.
6.Press the marble with the wooden handle of the hammer.
27. 7.In similar fashion, complete the floor. Finally, fill up the
joints of the tiles with White Cement.
8.First grinding of the floor should be done after a
minimum of five days of fixing the tiles with the help of a
grinding machine and carborandum stone.
9.Again apply White Cement slurry over the floor after first
grinding. And after one day, second grinding should be
done. A minimum of three grindings are recommended
for a good finish.
10.Wash the floor completely and polish it.
28. 1: Marble has a tendency to absorb the colour of base
mortar due to its porosity, which ultimately results in the
change of colour of the marble. So, a thin layer of White
Cement in the form of slurry provided in between the
marble and the ordinary cement mortar acts as a
separator.
2: It not only prevents the penetration of the grey cement
into the marble, but it also but it also helps in retaining
the original colour of the marble. But if the marble/granite
is opaque in nature, then ordinary cement could also be
used for making the slurry.
29.
30. • Tiles are most often made of ceramic
•Ceramic tiles are made of clay, sand and natural materials.
•They are burnt in kilns at temperature upto 1250 degree celsius.
•Ceramic tiles may be painted and glazed.
•Clay used in tiles is red, brown or white.
•They are very popular as both wall and flooring tiles and you can
even use them for entryways, benchtops or splashbacks if you
wish.
•These can be used any where : rooms, indoors, outdoors.
31. The initial step in ceramic tile manufacture involves
mixing the ingredients.
32. 1. Raw material preparation
2. Shaping
3. Drying raw tiles
4. Glazing
5. Firing/ burning
6. Sorting
7. Storage of ready
Product.
33. •Resistant from water and stain penetration.
•Difficult to crack.
•Can last over 20 years and more if well maintained.
•Replacing of tile is relatively simple.
•Donot need more maintenance.
•Can have many design options and shapes.
•Easy to clean, its resistant to stains, odours and scratches.
•Look -a vast array of choices in textures and colors to expand design patterns.
•Ceramic tiles are fireproof. They do not burn, nor give off smoke or toxic fumes
Since it is hard so it could be uncomfortable to stand on it.
May not be suited to environment.
This material does not hold on to heat very well, that means that it can get very cold in
the winter.
Ceramics are quite heavy, which means that they may not always be appropriate for
upper story installations.
34. Texture- Real feel of natural stone including slight
grains on surface.
Shape- Most commonly square or rectangular,
hexagonal, triangular, trapezium for unique designs.
Colour- Multiple colours.
Size- Ranging from 2”by2” to 24”by24”.
Weight- Starting from 1kg
Thickness- Starting from 10mm.
36. Porcelain tiles
Porcelain tile is more
scratch resistant .
Porcelain is made from a
finer, more dense clay.
Porcelain tile is fired at
temperature upto 2000
degree celcius.
Harder than ceramic .
Ceramic tiles
Scratch resistant but less
than porcelain.
Made from nomal clay.
Ceramic tiles are fired at
temperature upto 1250
degree celsius.
Hard surface.
37. Vitrified Tiles have got the name from vitrify which means the
process of making a glass or something similar to a glass. This tile is
known for its capacity to absorb water and also for being stain resistant.
• mixture containing clay and elements like silica, quartz and
feldspar.
• the mixture melts on applying a very high temperature(1200C)
• non-porous tiles that have a glassy texture.
• Vitrified tiles use a dye that is mixed with the clay before setting it on
fire. This dye makes the color consistent throughout the tiles.
Therefore, if the surface of the tile chips off, then a similar color is
exposed underneath.
• These tiles are thus, very strong, durable and resistant to water
and stain
38. • Aesthetics:-Vitrified Tiles come in every style to cover every theme and every
designer’s vision. with tiles.
• Hard wearing
• Easy to clean
• Attractive
• Fire Proof:-Vitrified Tiles cannot burn. After all, most are "fired" at 1200C.
• Resistant to chemicals
• Low allergy: will not give off cancer forming fumes.
• Breathe easy asthma approved
• Stable room temperature:-In the winter months, Vitrified tiles absorb heat during the
day and release it during the cooler evening. Acting as a heat bank, tiles saves the
money. During summer months, tiles are cool to touch.
• Tile size: The bigger formats (sizes) are possible in vitrified tiles which makes them as
an ideal tile for flooring
• Several technological factors : very high tonnage pressure, development of kilns
which can operate at high temperature (+1200C.), fine polishing machines, calibrating
machines and squaring and champ herring machines, development of nano material
technology to seal the residual water absorption, decorative printing technology etc.
have lead for this tile development.
39.
40. Due to its various advantages over other
flooring materials, Vitrified tiles are
commonly used worldwide in the following
places :
• Airport Terminal & Railway waiting
rooms
• Super Markets
• Healthcare Centres
• Club Houses
• Restaurants & Café
• Educational Institutes
• Hospitals
• Shopping Centres
• Private Houses
• Banks and offices
• Industries
• Workshop
• Public washrooms
41. 1. Soluble salt : tiles printed with screen printing technology and then polished are called
soluble salt vitrified tiles
Pros : cheapest type in indian market
Cons : design of soluble salt tiles fade away after a use of few years
2. Nano polished : when a layer of liquid silica is applied nano or micro pores are filled up
making the tile more smoother
3. Doubly charge : in this type of tile the press feeds two colours on the tiles bisque and
makes a thick layer of design of about 3-4mm ,used in high traffic areas
pros : long life as compared to traditional soluble salt vitrified tiles
cons: due to technology limitation design patterns are limited
4. Full body vitrified tiles : has colour all over the body of a tile, chipping and
scratching are less visible
pros: design will never fade
ideal flooring for high traffic areas
cons : very costly
less availability
limited design collection
5. Glazed vitrified tiles :vitrified tiles with glazed surface . It offers any type of
design/art work and texture like wooden, bamboo, slate
pros :designing possibility becomes infinite
cons :because of digital technology cost is very high

47. INTRODUCTION TO
CHEQUERED TILES
Chequered tiles are cement tiles or terrazzo tiles having grooves on
the surface of the tile which makes it anti-slippery. The chequered
groove can be in any shape and length, but the depth of the grooves
should not be less than 3 mm.
Chequered Coloured Tiles — Chequered tiles having a plain
wearing surface wherein pigments are used but not stone chips.
Terrazzo Chequered Tiles — Chequered tiles at least 25 percent
of whose wearing surface is composed of stone chips.
Monolayer Tiles — Chequered tiles on which there is only one
layer that is wearing layer, and which does not contain backing
layer.
Double Layer Tiles — Chequered tiles which contain a wearing
layer as well as a backing layer
48. Classification
Cement concrete chequered tiles shall be of two classes as
given below depending on the duty they perform:
a) General Purpose Tiles — Used for light traffic loads such as in
entrances and staircases of office buildings, schools, colleges,
hospitals and residential buildings and in footpaths and driveways
within building compounds.
b) Heavy Duty Floor Tiles — Used for heavy traffic
conditions such as in industrial godowns and industrial
workshop floors; platforms; ramps and entrances of public
buildings; passages of auditoriums; and in public footpaths
and pavements within commercial building.
50. MANUFACTURING
They shall be manufactured from a mixture of cement,
natural aggregates, and colouring materials where required,
by pressure process or vibration or both so that the tiles
meet the required strength.
The tiles shall be manufactured in single layer/ mono-layer or
in double layer.
The proportion of cement to aggregate in the backing of the
double layer tiles shall be not leaner than 1 : 3 by mass.
Where colouring material is used in the wearing layer, it shall
not exceed 10 % by mass of cement used in the mix.
On removal from the mould, the tiles shall be kept in moist
condition continuously for a period.
