A pile is a column of concrete that extends downward deep into the soil piled foundations consist of a number of piles connected by a ring of concrete called a ground beam. Pile foundations are used extensively for the support of buildings, bridges, and other structures to safely transfer structural loads to the ground and to avoid excess settlement or lateral movement. Pile foundations undergo the same principles as any other foundation firstly a site strip is excavated, removing the first 150mm of soil and debris this strip is then deepened to get a working level and to rid the ground of any contaminants. A pier is a raised structure typically supported by well-spaced foundation system the foundation system can be a pile, caisson or simple brick pillar based on the sub-soil condition the pile and caisson are set of deep foundations.
Pile foundation pile foundation pile foundations are deep foundations used when the site has a weak shallow bearing strata making it necessary to transfer load to a deeper strata either by friction or end bearing principles.

Pile foundations where the bearing capacity of the soil is poor or imposed loads are very heavy, pile foundations are required there are two main types of pile end bearing piles, where the pile acts as a column carrying the load down to the bearing strata, and friction piles, where the load is gradually transferred along the length of the pile. Pile foundations are used in the following situations: when there is a layer of weak soil at the surface this layer cannot support the weight of the building, so the loads of the building have to bypass this layer and be transferred to the layer of stronger soil or rock that is below the weak layer.
Piles have been used by mankind for foundation purposes since prehistoric times their behaviour, however, is far from completely clear and a substantial volume of research is being carried out on.

The pile foundations are classified on the basis of the material used in the making of piles, characteristics of the soil and load transmitting characteristic of the pile there are two kinds of pile foundation based on the load transmission characteristics, end bearing piles and friction piles.
