Cast in Place Concrete Piles
The second method was developed by a British piling company that has introduced a system which uses precast sections for the core of the pile. A hole is bored in the ground to the required depth and lined with a steel casting made up in convenient lengths. The precast sections are then threaded over a central steel tube to form the pile core.
