Pile foundation is the most flexible foundation in deep foundation category. This international handbook is essential for geotechnical engineers and engineering geologists responsible for designing and constructing piled foundations. The provision of more than one bulb along the stem further improves the performance of the pile and the latter is then called multi-undreamed pile. The pile and raft footing system is called as combined pile-raft foundation (CPRF) and has led to dramatic changes in the load carrying capacities of the foundation.
