I don't like being the one to say "the emperor has no clothes" but
the right thing to do is get a geotechnical engineer to check the
soil conditions and design a proper footing that will not settle.
Then jackhammer the old foundation out and replace it with a proper
one. If the foundation is settling as severely as you indicate,
it is simply not safe to continue using it.
