Flatwork Installers

Exposed and polished concrete floors require flatwork that is of the highest quality since it will not be hidden by carpet, tile, or other coatings. As such, it is important that flatworkers understand the unique needs of polished concrete so they can work hand-in-hand with the polishers to ensure the customers satisfaction with the project.
