If underfloor heating is installed insitu onto steel reo correctly and the concrete poured to the correct cover (thickness) over, there shouldn't be reason to see any cracking as a result from in-slab heating. If unsure, make sure to ask for references and see any previous jobs completed.

I know of this veneer concrete flooring as an alternative to lished concrete, however as a veneer, it is a thin pour over a solid substrate. Unfortunately the very nature of a first floor is suspended, (although sufficiently supported) it will have flex and movement in it, which this opttion does not favor. The reason is due to cracking, and resurfacing the cracks are unsightly. As a designer, and working on my own renovation, I looked into this option and the technical implications for my build. It was not recommended although possible. I did however find one other alternative, called xlite, which are large scale tiles that replicate the look of stone, marble and concrete too. The tiles run in 3000 x 1500 sheets, so Grout lines are limited and hardly factors. In fact that the unique scale of tile, which is lightweight and has a fantastic thermal mass, great insulative quality is so different, makes this system a feature on it's own.

Hi, I'm building a home with polished concrete throughout. I've noticed this post is a month old, so have you decided yet? I didnt' go with the usual aggregate as I felt it was too "busy". The concrete had charcoal dye added to the mix. I've seen pictures of it done with light colours as well and it looks good.
