ABSTRACT:
A method of forming a pile and a method for supporting a building structure by utilizing a pile so formed comprises driving a pile casing (19), with an enlargement (24) near its leading end (20) to a desired depth and supplying under pressure a settable mixture through the top of the casing so that it flows through apertures (26) at the enlargement to fill the oversize hole left by the enlargement around the casing. The casing can be driven through a hole formed in the building structure to be supported and the settable mixture may flow up the pile casing to fill a void under the structure.
