Sefi-Intrafor carries out deep foundation and underground work. The company also has an integrated engineering department and sizable installed machine base (mobile cranes, manufacturing and injection plants, etc.).

Founded in 1965 by Jacques Genest, SEFI (Société d'Etudes de Fondations et d'Injections) was taken over in 1994 by the Fayat Group, before buying out Intrafor in 2003. Sefi-Intrafor is one of the four companies making up the Fayat Group's Foundations division, alongside Franki Fondation, Sotraisol and Sols et Fondations.
