Couldn't the chimney be underpinned? If the primary cause
of failure is subsurface this might be easier to stabilise than
if, for example, the masonry had failed half way up...?
Perhaps ring-beam insertion or some form of non-percussive
concrete piling? Is there anyone on the list who knows about
such things who could put forward some ideas?
