DuPont Thetford Mines Manufacturing Facility


The DuPont Thetford Mines manufacturing facility is located in the city of Thetford Mines, Quebec. It is one of the two DuPont manufacturing facilities located in Quebec and the only DuPont manufacturing facility in the world to produce Corian® quartz.

Built in 1991 to produce Granirex marble slabs and tiles, the site was the first in the world to use quartz in its finished products or manufacturing process (one or the other). DuPont acquired Granirex Inc in 1998.

Today the site manufacturers a wide range of DuPont Corian® Quartz that are part of the Corian® Design Master Brand. Throughout its history, Thetford site has supported countless non-profit organizations in the Thetford Mines area through charitable giving and employee volunteerism.

Dupont Partners with Habitat for Humanity to Support Families Secure Safe and Affordable Housing

Last year DuPont Canada donated $ 30,000 (USD) to Habitat for Humanity International to support its Homes, Communities, Hope + You campaign in Canada. The funding was provided to Habitat for Humanity affiliates in Quebec and Kingston Limestone regions.

This donation enabled DuPont to directly support deserving families to secure much needed safe and affordable housing and show our gratitude to the Quebec and Kingston communities for their long-standing support for DuPont.

This is the second year that DuPont Canada has collaborated with Habitat for Humanity. In 2019, DuPont provided a financial donation and its employees volunteered at build days for a two-bedroom, single-story energy-efficient home in Sherbrooke, Quebec and a semi-detached dwelling in Kingston, Ontario for local area families.

DuPont Canada’s support is part of the Global company’s overall partnership with Habitat for Humanity International.
