You don't say how old the building is. If new, this could be a major
problem.
As someone has said you need to glue a glass telltale overt he crack &
leave for a few months. Some cracks are affected by weather
(ie,wetness of the ground, or frost esp.clay soils)

If still moving (ie the glass breaks) you are f**d. You will just
have to leave things and see how bad it gets. Make sure walls are not
likely to fall down etc.
If the glass remains intact after a year it's prob. OK & you can just
cement it up.

I don't know of any repairs to fractured concrete. It has broken
because it's too thin/weak or insufficient rebar.

As someone else said, no tiles, flexible or non attached floors only.
How did we get from foundation to floor - or are we in the habit of
tiling basement walls??
