[Concreateusa.com](http://Concreateusa.com) has a tongue and groove floor plank made from 1/2" thick concrete. Kind of like fiber-cement board, but different. It has a “polished” concrete surface. It gets installed like a wood floor board, set in a mastic. Planks are nominally 12" wide by 48" long.  
Is it:

- 09 30 36 Concrete Tiling
- 09 62 00 Specialty Flooring
- 09 60 00 Flooring, and leave it at that, or  
Should I propose a new section somewhere?

I like Specialty Flooring. That is certainly how a contractor will think of it.

Wood planking can be fairly tolerant of floor deflections. I would expect the concrete floor planks would not be as tolerant.

Mark:  
Can you suggest substrate deflection limits for the product?  
The planks are 75 inches in length. The adhesive has crumb rubber to allow some shear deformation.  
Would the limits be similar to large format ceramic tiles? What testing protocol is appropriate? Any thoughts would be appreciated.

I do not have specific criteria. My tendency would be to treat it the same as a 75" tile if they make such a thing.

Can the manufacturer provide you with a project where the product was installed on a similar suspended floor structure?
