Reverse Circulation, or RC Drilling, is a clean and environmentally friendly method of deep foundation installation. It employs dual-wall drill rods, comprised of an outer drill rod with an inner tube . As the sections of drill rod are screwed together, the inner tubes overlap and seal with O rings. This provides a continuous path for the drill tailings to be transported from the bit face to the surface.
