Different Kinds Of Deep Foundation

deep foundation is a sort of foundation which shifts building loads to the earth farther down from the surface than a shallow foundation works, to a subsurface coating or a range of deepness.

Additionally for ensuring steadiness and robustness of a structure there may be many other circumstances which may necessitate deep foundations. The most ordinary varieties of construction belonging to deep foundations are:
Piles : A long cylinder containing a strong material like concrete that is rooted into the ground to act as a firm support for structure built on top of it is called pile.
Pile foundation is needed when the soil bearing capacity is insufficient for the structure to endure. This is because of the condition of the soil or the arrangement of bottom layers, form of loads on foundations, circumstances at site and operational conditions.
In case of concrete pile foundations can be built with wood, concrete or steel and can be either precast or cast on site.
Caissons :caisson foundation is also termed as pier foundation is a watertight retaining structure used as a bridge pier, in case of the concrete dam construction, or for the ship repairing. It is a preassembled hollow box or cylinder sunk into the ground to some desired depth and then filled with concrete as a consequence a foundation is formed.
Caisson foundations are identical in appearance to pile foundations, but they are installed using a various technique. It is used when soil of ample bearing strength is found below surface layers of weak materials such as fill or peat. It is a structure of deep foundation which are constructed above ground level, then sunk to the needful level by excavating material from within the caisson.
Basement or Hollow Box Foundation : In case of this kind of foundation excavation is actualized and afterward foundation is built. Processes are quite alike to those used in foundations used in above ground level apart from that special consideration is given to water proofing and lateral earth pressure is considered in design.
