Short history: Founded in 1909 by the Stulemeijer family as Société Belge des Bétons (SBB), BESIX has evolved over more than a century from a Belgian concrete company to a multidisciplinary global leader. Key milestones include post-WWI port reconstruction, expansion into Europe and Africa, creation of Six Construct for Middle East projects in 1966, diversification into real estate in 1988, and a management buy-out in 2004 that led to the current BESIX Group identity.
