Title: RE: Auger Cast Piles

"Auger-cast", or more generically, "auger-grouted", piles are placed by rotating a continuous flight hollow-shaft auger into the ground to a predetermined pile depth. Grout is then injected through the auger shaft so as to exert removing pressure on the withdrawing earth-filled auger as well as lateral pressure on the soil surrounding the grout-filled pile hole.  There is never an open hole.  Reinforcing can lowered into the still fluid grout after the auger has been removed.

Please define for me "Auger Cast Piles." Is this what I know as a drilled caisson; which is a big hole drilled in the ground filled with a rebar steel  then poured with concrete?

In advance for the education, thanks.
