I work off and on w/ a shotcrete/gunnite (and other concrete repair
methods) contractor.  Very competent fellow.  They did some of the rehab
work on the Seattle Kingdome several years back - exposed bars in the
roof dome which had to be chipped out and gunnited overhead.

He has lectured Oregon SE's on the difference between shotcrete and
gunnite, although my experience is that the 2 terms are used
interchangably in the profession.

Monday I'll get some info to post.
