In my Patio Design I have a curved concrete bench in one corner, and I would like for it to be made like this River Rock seat I seen. Does anyone know how a seat like this would be made? I can not really tell if it has River Rock tile laid on top of the concrete or if it is totally made out of River Rock. I have yet to talk to a concrete contractor, but because I really like this look, I was thinking of incorporating River Rock into my design as an accent.
Thanks,
