Multition is a closed end steel pile, formed by two pipes of different diameters, driven by a rigid mandrel, cast-in-situ with concrete. Its main features are: the possibility of reaching very large depths to the bearing layer (from 30 to 60 m below ground level) and its capability to bear high axial loads (in spite of its relatively small diameter), in the range of the ones typical for large diameter bored piles. A detailed description of its general characteristics, method of installation and advantages and limitations are given in the paper. Discussion of site conditions, design features and construction are presented for several projects where the Multiton pile has found an ideal application, together with tests and controls executed to check its behavior.
