in floor heat

[flyingfossil]

Has any one ever have a problem with keeping a table level on a hydronic infloor heat system. It seems that I will level the table and a few days later it seems to start rolling funny. I make slight adjustment to compensate, that works for a while but then it happens again. Concrete expands, that I understand, but would it raise and lower that much?

Well what kind of table is it? Do you have an accurate level to really see the dif?

Floor Disturbance

Is the concrete floor a slab on grade. If so then moisture changes in the underlying soil can cause continual floor disturbance. This is especially true of soil with a high clay percentage in it's makeup. The average home owner would never notice this but it will sure show up on a pool table!
