A pile cap
is a thick concrete mat that rests on concrete or timber piles that have been
driven into soft or unstable ground to provide a suitable stable foundation. It
usually forms part of the foundation of a building, typically a multi-story
building, structure or support base for heavy equipment. The cast concrete pile
cap distributes the load of the building into the piles. A similar structure to
a pile cap is a "raft", which is a concrete foundation floor resting
directly onto soft soil which may be liable to subsidence
