Lab Flooring

We're looking into doing something about our old tile floor.  New tiles?  Some type of sealant over the old tiles?  Rip out the old tiles and replace with some sort of solid sheet flooring or with an epoxy base coating??


Does anybody out there have a good, bad, or ugly experience with a lab floor retrofit?  Or info about the pros and/or cons of various materials?


We would be looking something that would be solvent (hexane and methylene chloride) and acid proof or resistant or whatever.


Thanks in advance,

Thanks to everybody who emailed info.  The root cause of our problem was 12-ft wide sections of the building cement pad moving and grinding into one another.  This caused tiles along the section seams to crack, shatter, and buckle.


After looking at the various options, we decided to stick with the existing tile squares, which are still available.  The old tiles will be taken up along the seams, the seams ground flat, and new tiles put down.  The contractor will use some sort of high-tech coating on top instead of the traditional floor wax.  Keeping the lab clean during the grinding operations will be quite a challange.


Of course, this does nothing to stop the building pad sections from moving/settling/whatever in the future, but at least any fix will be hopefully around 20 years from now.
