[Greenbuilding] Redoing all floors

[Ktot (g)]

Hmmm, interesting about the concrete and water. And your tile comments. The 
tile people I've talked with used a different term for porcelain that has 
the color/pattern going all the way through (so can be cut, chipped, etc. 
and still show the pattern), but I don't remember what their term was. Also 
I don't think that involved everything you're talking about re hardness and 
such.
