Polished concrete is a concrete slab that is polished down until a smooth, shiny finish is achieved.  It is a popular choice for commercial spaces such as warehouses and retail locations etc.
Recently homeowners are utilizing this technique for low maintenance interior flooring.

You start with a rough pad and grind into the concrete. Then you move to smoother and smoother diamond grinding pads, step by step, until your finished product is a shiny, smooth floor.  

Grinding into the concrete will usually expose aggregate which can provide an extra richness to the surface.
