5. Steps of Anti-termite
Treatment
• The first and the most important part is the site preparation. The
removal of trees, stumps, roots etc. from the site reduces the chances
of an attack by the termites.
• The sides and bottom surfaces of the foundation trenches and pits
are treated with chemicals.
• The backfilled soil of the built up wall is treated. The chemicals
are directed towards the masonry surfaces so that the earth in
contact with such surfaces is well treated with chemicals.
• The top surface of consolidated earth within support walls is treated
with chemical emulsions.
• The treatment of wall and floor junctions is done to ensure
continuity in the vertical chemical barrier.
• The earth on the external perimeter of the building will also be
treated to ensure maximum protection.

6. Advantage Anti-Termite
Treatment
• Safely the pest control chemicals are injected into the
soil where it crystalises and stays no direct contact
with the occupants.
• The precaution treatment is more effective than
alternative treatments.
• The chemical barrier can protect your home for years.
• Most pest control companies give a warranty for ten
years in pre- construction treatment.

7. CONSTRUCTION OF PILE
FOUNDATION
Piles are relatively slender shafts, cylindrical in
shape, driven or bored into the ground to the
required depth. Piles are used to carry vertical
loads through weak soil to dense strata having
high bearing capacity.
FUNCTION OF PILES:
a) to transmit a foundation load to a solid
ground.
b) to resist vertical, lateral and uplift load.

8. Concreting of Pile

9. Advantages of pile:
1. Length can be readily varied to suit varying ground
conditions.
2. Soil removed in boring can be inspected and if
necessary sampled or in- situ test made.
3.Can be installed in very large diameters.
Disadvantages of Pile:
1. Susceptible to "wasting" or "necking" in squeezing
ground.
2.Concrete is not placed under ideal conditions and
cannot be subsequently inspected.
3.Water under artesian pressure may pipe up pile shaft
washing out cement.

10. STATIC LOAD TEST ON WORKING PILE

11. TESTS ON SOIL BEFORE STARTING
CONSTRUCTION WORK:
• WATER CONTENT
• FREE SWELL INDEX OF SOIL
• PLASTIC LIMIT OF SOIL
• LIQUID LIMIT OF SOIL
• PARTICLE SIZE DISTRIBUTION OF SOIL
• THE SPECIFIC GRAVITY OF SOIL
• THE IN-SITU DRY DENSITY OF SOIL BY SAND
REPLACEMENT METHOD

12. BAR BENDING AND PLACEMENT OF
FOUNDATION STEEL
• REINFORCEMENT
• BAR BENDING SCHEDULE
• LAP LENGTH
• ANCHORAGE LENGTH
• CRANK
• HOOK
• COVER BLOCK

13. Structural
element
Cover to
reinforcement (mm)
Footings 40
Columns 40
Slabs 15
Beams 25
Retaining wall 25 for earth face
20 for other face

14. BRICK WORK

15. LEVELLING:
Leveling is a method to set slabs and beams in
same height throughout. To level slabs and beams
shuttering we tighten or loosen the jack
according to auto-level machine.
Concreting:
Concrete is a heterogeneous mixture of
cementing material, aggregate and water. It’s
provide a solid bonding structure and gives
required strength to building members.

16. DOORS AND WINDOWS:
Doors and windows frames made of wood are fixed to masonry by
providing HORNS.
Height of frame=Height of opening+4cm
Size of door shutters without sill:
Height=height of opening-frame thickness-bottom clearance +
rebate.
Width=width of opening-2*frame thickness+2*rebate
PLASTERING:
Plaster is a building material used for coating walls and ceilings.
According to IS Code the plastering of inner wall is 15 mm thick, for
outer wall is 20 mm thick and the ceiling plaster is 10mm thick.

17. TESTS IN SITE:
COMPRESSION TESTS ON
CONCRETE CUBES
SLUMP TEST
