About us


The Bamberger Natursteinwerk Hermann Graser is a medium-sized family business that has continuously developed into a leading company in the natural stone industry since the company was founded in 1965. The company focuses on facade construction with natural stone as well as the restoration and reconstruction of historical monuments. The portfolio is rounded off with the production of natural stones for public places and garden and landscape design. The company's range of services extends from the quarrying of raw blocks in its more than 20 own quarries, its own planning and design offices, production in its own factory to construction services with its own staff on site. The company's particular strength is the combination of traditional stonemasonry techniques with innovative production processes, such as the automated processing of natural stone with industrial robots.
