摘要

A foundation pile is produced using a tube (1) which is radially outwardly deformable in one or more regions along its length, eg having longitudinal slits (4) in such regions defining tongues (6) therebetween. The or each such region deforms outwardly during filling of the tube with concrete or analogous material, producing one or more anchoring swellings (20) which provide the pile with improved resistance to compression and tension as compared with conventional piles.
