A century of expertise

Our 120-year old heritage makes us a true family business. Marbrerie Bertrand evolved from a small workshop to a full-service stonemason, covering stone sourcing, manufacturing, installation and project management.

The company was founded by the Bertrand brothers in 1902 as a sculpture workshop in the village of Munsbach. Since then, each generation of the Bertrand family further developed and diversified the company’s activities. Today, Martine Bertrand, Marc Bertrand and Stéphane Lenert lead the company.

Who we are

Marbrerie Bertrand sources, processes, and installs natural stone. We source directly from quarries and suppliers all around the world. We keep an extensive stock on our 3.000 m2 stone yard and welcome our clients in a showroom displaying the wide variety of natural stones available in the world. We process the stones for our projects in our 2.500 m2 workshop in Munsbach. 

We have a diverse team, who speaks over 10 languages, and offers a diverse & international know-how. This helps us source stone internationally, adopt the best building practices from around the world, as well as serve our customers in the best way possible.

How we work

As a family business that has existed for over 120 years, at the heart of our company’s values are our commitment to sustainability, craftsmanship and social responsibility.

Our design principles are defined by our aim to deliver durability, sustainability and timelessness. Well-maintained natural stone embodies these principles by lasting for multiple generations. While stone as a construction material has already a low carbon emission footprint, we are committed to go further. In our pursuit of sustainability, we installed solar panels to power our workshop and we conduct regular CO2 footprint analyses, in order to achieve our goal of becoming a Net Zero company in the coming years. 

Moreover, we continuously modernize our workshop, and invest in training young generations of stonemasons. That way, Marbrerie Bertrand preserves its heritage, knowhow and social responsibility.
