1. A method of assembling conduit sections, the method comprising the steps of:
providing a first conduit section within an associated concrete slab: providing a connector sleeve;
adhering said connector sleeve with adhesive to said first conduit section so that said first conduit section extends upwardly within said connector sleeve;
depositing concrete about said first conduit section and said connector sleeve to a grade level such that a top of said connector sleeve is at a same height as the grade level of the concrete;
providing a coupling element having a lower polymeric section, and an upper section;
adhering said coupling element with adhesive to said connector sleeve, with said polymeric section of said coupling element extending downwardly within said connector sleeve, so that said coupling element projects above said deposited concrete; and
joining a second conduit section to said upper section of said coupling element, to thereby join said second conduit section to said first conduit section,
wherein said connector sleeve includes an internal, annular shoulder, said first conduit section extending upwardly within said connector sleeve to abut a lower surface of said internal, annular shoulder, and said lower polymeric section of said coupling element extending downwardly within said connector sleeve to abut an upper surface of said internal, annular shoulder.
