By: ZafarMehdi

2. FLOOR
Structural component made to provide a level surface .
It is a horizontal sanitary surface that supports the occupants of
a building, furniture and equipment.
STRUCTURE OF A FLOOR.
The floor is divided into three components
Sub base
Base concrete
Floor finish

3. Cleanliness-
The flooring should be capable of being cleaned easily, and
it should be non-absorbent.
Resistance-
Should have effective resistance against absorption of oil,
grease etc.
Durability -
The flooring should have sufficient resistance to wear,
temperature changes, disintegration with time and decay.
Tiles, marble, terrazzo, concrete, mosaic etc. are
considered to be of best types.
SELECTION OF FLOORING MATERIAL

4. Hardness-
It should be sufficiently hard to resist indentation
marks, imprints etc. likely to be caused by shifting of
furniture, equipments etc.
Maintenance -
Flooring material should require least
maintenance, repairs can be done easily.
Tiles, marble, terrazzo, concrete etc. require less
maintenance.

6. STONE FLOORING
There are following types of stone flooring –
1-marble flooring
2-granite flooring
3-kota stone flooring
Marble flooring
Marble flooring is commonly is provided in places of
worship and in public buildings having rich specification.

7. CLASSIFICATION OF MARBLE

COLOURED MARBLE

9. The size of marble slabs to be used in flooring depends
upon the pattern to be used.
The slab for normal works are square or rectangular in
shape and their thickness varies from 20 mm to 40mm.
The flooring is laid on prepared sub grade of concrete or
on RCC floor slab.
Before laying of flooring, the sub grad4e in cleaned wetted
and mopped properly.
Then a layer of bedding mortar which can be 1:4 cement
mortar(1 cement:4 coarse sand) or lime mortar is spread
in average thickness of about 20mm under the area of
each slab.
The marble slab is laid on the top of the bedding mortar,
pressed and tapped with wooden mallet.

13. GRANITE FLOORING
Granite has fine
grains and it is
harder than marble

14. TYPES OF GRANITE
There are mainly three types of granite-
GREEN GRANITE RED GRANITE
BLACK GRANITE

15. KOTA STONE FLOORING
Kota stone is commanly 25 to 40 mm thick.
It should be hard, sound,dense and homogenious
in texture.
it is done to obtain smooth surface.

16. LAYING
Same as that of marble
Except that the edge of slab to
be jointed shuold be buttered
with grey cement.

17. Tiled Floors

18. Tiled Floors
The usefulness of tiles as a flooring material is due to
Their pleasant appearance.
It eliminates the possibility of cracks.
Quick execution of flooring
Constructed from square, hexagonal or other shapes
Made of clay ( pottery), cement concrete or terrazzo.
Available in different sizes and thicknesses.
Commonly used in residential houses, offices, schools,
hospitals and other public buildings, for floor to be laid quickly.

19. BASE FOR TILE FLOORING
Flooring may be laid on reasonably rigid base.
Surface of the base shall be rough to form suitable key
with bedding mortar.
The base, about 35 to 50 mm below the level of the
finished floor, to be properly graded and free from lose
earth, dirt, dust and lumps.

42. TERRAZZO FLOORING

43. The area is divided in to suitable panels of predetermined size
and shape
Strips are jointed to base concrete with help of cement mortar
Thickness of strip may be 4 to 6 mm.
Surface of base concrete is cleaned and wetted and then base
concrete is laid in alternate panels.
The surface is then cured for 7 days.
It is then scrubbed and cleaned thoroughly and cement grout
is applied again.
After 6 days curing, final grinding is done with carborundom
stone of 320-grid size.
Then it is washed with dilute oxalic solution and finally
the floor is polished with the machine

The propotion of terrago mix depends on the size of
marble chips. But is generally taken 1:2 to 1:3 i.e. one part
of cement to two or three pats of marble chips by
volume.
The total thickness of terrazo flooring is about 20mm.

47. TERRAZO FLOORING

48. BRICK FLOORING

49. It is used where
Cheap construction is done
Places where heavy articles are to be
stacked.
MATERIALS
Brick
Lime or Cement mortar
Base concrete generally 75mm thick of
ratio of 1:4:8 and lean cement concrete
1:5:10.

50. General
LAYING OF BRICKS
Bricks are laid on edge and on bed.
The joint between the brick should not exceed10mm
thickness
The brick is protected from rain when mortar is still green.
The usefulness of bricks as flooring material lie mainly in their
good wearing quality and ease of quick installation. The
performance depends on the quality of bricks, bedding prepared
and the laying is done. It’s done generally in low cost areas.

51. Laying
•The bricks shall be laid on the edge on 12mm mortar bed in plain or
diagonal herring bone pattern.
•Each brick should be properly bedded and set home by gently
tapping with wooden trowel handle or mallet.
•Its inside face is applied with mortar, before the next brick is laid
and pressed against it.
•On competition of a portion of flooring the joints should be filled
with mortar.
•The surface of the flooring during laying should be frequently
checked with a straight edge.
Curing
Brick work should be protected from rain by suitable covering
when the mortar is still green. Brickwork shall be kept constantly
moist on all faces for a period of 7 days.

53. CEMENT CONCRETE FLOORING

54. Consists of cement concrete(1:2:4)
thickness of 25,40 or 50mm.
Laid over base concrete after proper sub base
preparation
QUALITIES
Smooth, hard and pleasing in apperance.
Posses good durablity.
Economical.
Does not required proper maintenance.
Required skilled labor.
Does not equalize the temperature.
Can be easily cleaned
Can carry expected loading and traffic.

55. USES
•This is one of the most common flooring used throughout the
world for nearly all types of buildings like houses, shops, hospitals
etc.
DESIGN CONSIDERATIONS
•CHOICE OF AGGREGATE: should be hard enough for good durability
as well as abrasion resistance.
•WATER CEMENT RATIO: lower the water cement ratio, greater the
durability and wear resistance.
•DENSITY OF FLOORING: flooring should be well compacted.
density is increased with increase in density of finish.
•CURING: adequate curing is essential to ensure good wear
resistances

56. CEMENT CONCRETE FLOOR FINISH
Finish is laid with base concrete on ground.
Topping is laid within 2-3 hours of laying the base concrete
Base concrete imparts strength and have good wearing
properties.
,
Base concrete
Consists of 100 mm thick1:4:8 cement concrete
Before placing the base concrete, the sub base should be properly
wetted.
Surface should not be finished smooth but kept rough to provide
adequate bond for topping.
Floor finishing
Topping consist of 1:2:4 cement concrete with a minimum
thickness of 25 mm. Topping should be placed in position as soon
as possible but not later than 2to 3 hours of laying

57. Prep of base from (brick ballast)

58. CEMENT CONCRETE FLOORING

59. TIMBER FLOORING
Flooring in which timber is used is known as timber flooring.
•It is the most common flooring and it possess natural
beauty.

60. MATERIAL USED IN TIMBER FLOORING
In Artificial wooden flooring M.D.F boards are used
For natural wooden flooring teak, oak, shesham etc
are used.
Different types are adhesive used in tmber flooring
CONSTRUTION METHOD -
Steps used in timber flooring-
Firstly ground is levelled and compected properly.
Over the compacted surface of ground,a layer of lime
Concrete 10-15 cm. or cement concrete 5 to 8 cm
thick is laid and properly compected.
Small walls at a distance of nearly 1.5 to 2.0 c/c are
constructed over the concrete bed.

61. Over the dwarf walls, timber beams generally 8x10cm.in
size ,
called sleeper or needle are laid.
The wooden boards ,generally 2-3 cm. thick and
maximum width of wooden boards recommended is 10
cm.
In another type of timber floor asphalt layer about 6mm.
Thick laid over the lime cement concrete base.over this
base timber joints are laid dividing the floor area in
square or rectangles.timber planks 3-4 cm. thick over
these joints.
The wooden planks are joined by tongue and groove.
