A brief guide to Pile Footing with graphical representations and examples. This presentation is enough to get basic information about piling; deep foundations. Good luck to every student.

2. HISTORY OF PILE
FOOTING
Pile foundations have been used for many years,
for carrying and transferring of loads to soil
considered to be weak in structure due to the soil
conditions. In the early stages of development,
villages and towns were located in the close
vicinity of lakes and rivers due to the availability
of water, and, also, to ensure proper protection
of the area. Therefore, the weak bearing ground
was reinforced by the use of timber piles that
were either manually forced into the ground, or
fixed in holes that were filled with stones and
sand. The primitive methods of pile installation
were modified after the industrial revolution, and
techniques of installation by steam or diesel
driven machines were introduced. With the
advancement in the technologies of soil
mechanics and other related disciplines, superior
piles and pile installation systems have been
developed.

3. CONSTITUENTS
These pictures clearly represent the parts of
the piles. It is easily understandable from the
pictures that how the piling process is caried
out and how each and every element plays
its role in the strength, stability and durability
of the footing.

5. PROPERTIES
1. Piles are good at handling large loads.
2. They are very useful in places where soil
bearing capacity is weak.
3. Also they are used where we need
greater amount of strength like in high
rise buildings.
4. They directly transfer loads to the
bedrock, a small amount of settlement is
allowed. Hence no room for failure of
the building foundation.
5. This is although an expansive process but
very durable and sustainable.
6. There are different types of piling
available depending on the situation,
condition and need.

6. JOINERY DETAILS
Here, we can clearly see the
process of pile construction. A drill
is made from ground level to the
bedrock, then a reinforcement
steel cage is inserted into the drill
and at last the hole is filled with
solid concrete. After the piles are
ready, pile cap is made on top of
the piles to held them in place. Its
like the beams holding the walls.
And after this the construction is
done on the piling setup. It is the
strongest foundation and allows to
efficiently use the lands with weak
soils.

7. SECTIONAL
DETAILS
It is clearly visible here that how
the process of piling is carried
out. How the piles are drilled to
the less compressible layer of
Earth. The reinforcement and
materials of are also clearly
visible here. After the pile cap is
made, any kind of super
structure can be build as the
piling sequence acts as a
foundation.

8. PROS AND CONS
• High load capacities and corrosion resistant.
• Transmits the foundation load to solid ground regardless
of the place of construction.
• Can carry heavy loads easily.
• Size and depth are customizable.
• A little settlement makes it stronger.
• Can be installed in a large area.
• We can use piles in a place where drilling and holes are
not done.
• There are types of piles that are easy to handle.
• Quality of material is good in precast.
• Its noise level is not high.
• Some acids can cause damage to the concrete and may
occur salt water reactions.
• It is an expensive task.
• Number of piles determine the loads to be taken; more
piles are to be drilled for larger loads.
• Flexibility in design makes it expansive.
• A small error can be very dangerous.
• Huge budget is required for large project.
• Vibrations generate when piles are driving which affects
the neighboring structures.
• All the materials for piles is not readily available of every
site.
• Precast piles could break while driving.
