Details of Deep Foundation

A deep foundation means a type of foundation that disperse building loads to the earth more distant down from the surface, what a shallow foundation perform, to a subsurface layer or a range of depths. A pile refers to a perpendicular structural element of a deep foundation, directed or drilled deep into the ground on the building site.

Deep foundations are set up too intensely under the finished ground surface because of their base bearing capability that can be influenced with surface conditions. It is generally remained at depths >3 m under finished ground level.

Deep foundation is designed to bear loads from a structure via frail compressible soils or fills on to robust and less flexible soils or rocks at depth, or for functional reasons.

If, the strata of good bearing capability does not exist adjacent to the ground, the foundation of the structure should be rooted deep to facilitate obtaining a bearing stratum that is appropriate in all respects.

Besides, there are other conditions for which deep foundations are essential for the consistency and longevity of a structure. Generally, the deep foundations are essential for the various types of constructions like piles, caissons and basement or hollow box foundation.

Piles
A pile refers to a long cylinder of a solid material like concrete that is digged into the ground to provide a strong support for structures constructed on top of it.

Pile foundation is useful when the structure can’t resist load due to low & insufficient bearing capacity of soil. This happens because of the soil condition or the order of bottom layers, type of loads on foundations, conditions at site and operational conditions. Pile foundations are formed with wood, concrete or steel and can be either precast or cast on site in case of concrete.
