Driven precast concrete piles are constructed by hammering the piles into the soil to a depth greater than 40m by an adjustable hydraulic or diesel hammer. ... These piles can be used for the foundation of all types of engineering structures under nearly every soil condition.
Piles are manufactured off-site in standard lengths, and driven into the ground using self-erecting hydraulic piling rigs with hydraulic hammers until the required depth/resistance is reached. Piles can be jointed using the Multijoint (Mechanical Interlocking Joint) or the UNIjoint (for compressive loading).

Are precast pile generally used is?
Pre-cast pile generally used is in form of square cross section with chamfered corners. Using this square cross section with chamfered corners has three advantages: As the corners are chamfered, a) The surface area of the piles gets increased
