Concrete floor moving

We are experiencing problems with some large machine tools we have moving, is this type of work you do ? The machines are moving approximately .001" in 24 hrs.
If I understand correctly, your problem is that the whole concrete floor is moving 0.001" per day. If that is the case it may be necessary to reinforce the foundations after investigating the soils.  This should be done by a local soils/structural engineer.

I assume that the machines are not just moving over the floor because that would probably be fixed by bolting !?

By the way, how do you measure such movement? Relative to what?

Interesting problem but I believe you need to get a local expert. If you need help locating one I may be able to help with that.
