Our subsidiaries

Five subsidiaries, from quarry to construction site

Belza Groupe brings together five industrial subsidiaries, founded between 2008 and 2023 around a single principle: control every stage of the material, from rock extracted at the quarry to paving laid on site.

More than 1,000 completed projects and over 6,000 partners later, more than 80% of the group's clients stay on as long-term partners.
