Systems and methods are provided for establishing and securing a foundation in a substrate. For example, in one embodiment, a pump conveys a first fluid (e.g., water) through a pile member to produce an elongate opening in a substrate, which allows the pile member to be advanced into the substrate. After the pile member has been advanced into the elongate opening in the substrate, a second fluid (e.g., fluidized concrete) is conveyed out of openings on the side (and the bottom) of the pile member to substantially secure the pile member in the elongate opening defined in the substrate.
