We are Avant Design, Inc., a New York City based concrete polishing company. We polish concrete floors in commercial, industrial, and residential buildings. We use the most enviromentally sustainable, green methods; we diamond polish the actual concrete in a multi-step process up to as high as #3000 grit, by using progressively finer and finer diamonds to mechanically abrade, hone, and polish the surface. We use the finest penetrating densifiers and sealers that don't leave any plastic film on the surface that would keep you from the feel of the smooth, durable, breathable, polished concrete.
