A pipe assembly may have one or more pipe segments that are coupled together or coupled to a drive socket by a coupler. The bottom-most pipe segment being a bottom pile segment that may have a body with a central axis, an exterior surface an upper end connectable to the pipe pile assembly, and a bottom end, the bottom end inhibiting grout from passing through the bottom end, helical flights extending from the exterior surface of the body substantially perpendicular to the central axis, and grout ports through which the grout is emittable. The bottom pipe segment is designed to receive grout introduced through the pipe assembly so that the grout can be emitted the grout ports during the driving of the pile assembly into soil. The emitted grout forms a grout/soil mixture jacket within the disturbed soil along an exterior of the pipe pile assembly which adds appreciably to the overall stability, and particularly the lateral stability, of the pipe pile column created.
