I wouldent, not at all.
I'd use a bump map with a layered shader for the cement and the tiles so there are different material properties for each, your just using geometry for no real reason.
Depending on the level of realism, you can use a Grid texture in the procedural textures library, you can also use this as a bump and spec map.
