Hi...I have seen this done on a television show for a house in the west...I think it was in Arizona. I will check out diff. websites and see if I can find the information on how this is done, as I can only remember so much. I do remember that they used foam forms and basically they poured a slab (this one had black pigment mixed in for a nice color effect) onto the reinforced cabinet base (concrete counters are very heavy). Anyway, they did use reinforcement, but I can't remember if it was rebar or remesh. I'll try to find out...the concrete was finished just like any ordinary sidewalk, etc with floats and corner tools. I'll get back to you about it if I find anything. Jeff
