Bamberger Natursteinwerk Hermann Graser

What Bamberger Natursteinwerk Hermann Graser does

Bamberger Natursteinwerk Hermann Graser GmbH is a privately held, family-owned German natural stone company founded in 1965 and headquartered in Bamberg. The firm operates across the full natural stone value chain — extracting raw blocks from its own quarries, executing planning and construction design in-house, manufacturing finished products in its own workshops, and dispatching its own personnel for on-site installation and restoration. Its core commercial offerings are natural stone facades (Natursteinfassaden), reconstruction (Rekonstruktion), restoration of historical monuments (Restaurierung), natural stone paving (Natursteinpflaster), stone masonry and sculptural work (Steinmetz- & Bildhauerarbeiten), and interior and exterior installations for private and commercial customers.

The company serves four principal customer groups: enterprise clients — chiefly architects, planners, public institutions, museums, and religious and commercial real estate developers procuring facade and restoration work; resellers and stone contractors purchasing raw blocks, slabs, and semi-finished products; private homeowners purchasing finished stonework for residential and garden applications; and memorial/cemetery clients requiring bespoke monuments. Revenue is generated through project-based contracts (one-time licenses), direct material sales, and professional consulting/planning services, with pricing established on a quote-by-project basis rather than via public list pricing. The firm has won Deutscher Natursteinpreis awards in 2018, 2020, 2022, and 2024 across multiple categories and operates across major German cities (Berlin, Dresden, Hamburg, Frankfurt, Heidelberg, Mannheim, Potsdam) with at least one documented Netherlands-based project.

Recent product activity has broadened the surface area beyond traditional facade and restoration work, including Tragender Naturstein (load-bearing natural stone), Vorgespannte Natursteinbauteile (prestressed stone elements), Roboterfertigung / 3D-Fassaden (robot-assisted 3D facade fabrication), Natursteindächer, freitragende Natursteintreppen (cantilevered stone staircases), Elektroladesäulen aus Naturstein (eMiliarium EV charging stations in stone), and the Grasamit proprietary restoration mortar line. CE marking is maintained for key stone products (Neckartäler Hartsandstein, Postaer Sandstein). The company is managed by the Graser family, with Hermann Graser as Geschäftsführer and Hermann Graser jun. and Martin Graser as additional directors; ownership is concentrated within the founding family with no disclosed external investors.
