A deep foundation is a type
of foundation distinguished from shallowfoundations by the depth they are embedded
into the ground

Displacement piles
Piles which are driven are termedDisplacement Piles because their installation
methods displace laterally the soils throughwhich they are introduced.
Replacement piles
Piles that are formed by creating a borehole
into which the pile is then cast or placed, arereferred to as Replacement Piles becauseexisting material, usually soil is removed aspart of the process.

A driven pile is a deep foundation that is constructed by
driving a concrete, steel or timber pile.
To support the anticipated load in competentsubsurface material.
Prefabricated concrete piles are driven using a pile
driver equipped with a hydraulic free fall hammer.
Prefabricated concrete piles are primarily used in loosesoils.

A bored pile is a deep foundation that isconstruction by removing the soil in the pilelocation by an excavating tool (bucket- auger-
core barrel- etc..) to correct depth When the drill has arrived at the correct depth,
the pile is concreted using a tremmie pipe orpumped through the end of the centre pipe

A monopile foundation utilizes a single,generally large-diameter, foundation structural
element to support all the loads (weight, wind,etc.) of a large above-surface structure.
