What might be very simple and totally possible is to trench down a
couple of meters about a foot from the footings, and fill that with
concrete. That would cut the roots there, and stop any further

shallow.


Roots are pretty persistant and can get through concrete so I wouldn't
leap into doing this without more research. Maybe a plastic board
would stop the roots better


Roots cannot get through uncracked concrete. But I take your point.
