What Sefi-Intrafor does
Sefi-Intrafor was a French specialty contractor in deep foundations and underground works, founded in 1965 and headquartered in Grigny, Île-de-France, with approximately 206 employees. The firm provided project-based construction services across five core technical domains: deep foundations (pieux, fondations), micropiles (micropieux), ground injection and consolidation (injections), earth retention systems (soutènement), and quarry consolidation (consolidation de carrières), supplemented by a proprietary product line branded Gamme Biocofra. Its customer base was enterprise clients executing complex infrastructure projects in France, with no consumer-facing product and no disclosed recurring-revenue or SaaS-style pricing model; engagements were tendered on a per-project, quote-driven basis typical of the BTP (Bâtiment et Travaux Publics) sector. Go-to-market was direct sales to enterprise project owners, supported by a top-of-funnel presence on LinkedIn, Facebook, Instagram, and YouTube under the Fayat Fondations brand, plus a dedicated careers portal for recruitment. Following its merger with Franki Fondation, Sefi-Intrafor ceased to operate as a standalone entity and was absorbed into Fayat Fondations, the foundations division of the diversified Fayat Group (Groupe Fayat), where its heritage, teams, and specialized expertise continue to be deployed.
