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.
What exactly is concrete?
1 : a mass formed by coalescence of separate particles of matter, suspended in a fluid such as water, into one body
2 : a hard strong building material made by mixing a cementing material (such as portland cement) and a mineral aggregate (such as sand and gravel) with sufficient water to cause the cement to set and bind the entire mass
Concrete, as we generally know it, consists of portland cement; cement is an ingredient of concrete, along with graded sand, and a larger aggregate, in a diameter of from three-eighths of an inch, or pea-size, up to three quarters of an inch in diameter, made from crushed bluestone, granite, limestone, graded river rock, or a man-made, lightweight aggregate, to produce lightweight concrete.
Concrete has been used as a building material since at least 800 BC by the Greeks, some of whose structures are still standing today!
What then, is polished concrete?
We are all familiar with concrete as it is used in everything from our sidewalks to our bridges, in our houses and high rises, but although its use continues to increase, many aren't yet familiar with this versatile substance when used as an interior finish. Concrete itself can actually be polished to a high gloss, resembling marble or granite, yet with its own unique set of characteristics.
Polished concrete gives an unparalleled tactile sensation: a warm feel and texture unlike any other material. It can be refined to be as smooth as stone which has been shaped, smoothed, and polished by the sea.
We polish concrete with heavy machines, specifically designed to turn diamond segments or pads on the floor, first to grind, in order to flatten, remove flaws and discoloration, then to hone, to remove large scratches, and finally to polish, again, with each step using progressively finer and finer diamonds.
Polished concrete has many advantages including a low price/performance ratio when compared to other types of flooring. Click here to see a chart comparing polished concrete with other options; you may be surprised!
