What Groupe GISONE does

Groupe GISONE is a French family-owned precast concrete manufacturer founded in 1971 and headquartered in Auriol (Bouches-du-Rhône). The company operates two production sites — Auriol near Aubagne and Tarascon near Arles — encompassing 7,800m² of covered manufacturing space and 70,000m² of outdoor storage, with a stated annual capacity of 32,000 tonnes and approximately 50 employees. It runs through two legal entities: SAS GISONE Béton Vibré (capital €50,000) and SAS GISONE Préfa (capital €300,000).

The company produces eight core product families: drainage channels (caniveaux), dry-network telecom chambers (réseaux secs), road infrastructure (voirie), inspection chambers (regards), retaining walls (murs de soutènement), RTE-certified electrical products, custom civil engineering (Génie Civil), and special custom prefabrication (Préfa spéciale). Underlying capabilities include an in-house steel workshop for custom mold fabrication, a proprietary low-carbon concrete formulation using blast furnace slag (23% CO2 reduction, launched January 2024), and an ECOncrete-certified marine ecological concrete module developed through a 2024 partnership. The company has held NF certification since 1991, CE marking since 2016, and products rated up to E600/F900 load classes.

GISONE serves major French BTP groups (Vinci, Bouygues, Eiffage, GTM SUD, Eurovia), airport operators (Aéroports de Paris, Nice, Blagnac, Rennes, Le Bourget, military air bases BA702/BA115/BA125/BAN Hyères), RTE for electrical transmission infrastructure, water utilities (SCP, SEM), and premium Mediterranean marine projects in Monaco (Mareterra, Larvotto Beach). Revenue is generated through both direct enterprise contracts and a négoce (building materials trading) distribution channel. FY2024 revenue was reported at €10 million. Recent strategic moves include the Tarascon site expansion (November 2024), low-carbon product launch, EV charging foundation introduction in the 2025 catalogue, and marine ecological module expansion.

Core offering

Groupe GISONE is a family-owned French manufacturer specializing in the prefabrication of reinforced concrete products for public works, civil engineering, and building sectors. Operating two production sites (Auriol and Tarascon) with 50 employees and 32,000 tonnes of annual output, the company produces both standard prefabricated elements (drainage channels, telecom/utility chambers, road infrastructure, inspection chambers, retaining walls, RTE-certified electrical products) and custom civil engineering pieces up to 25 tonnes per unit, including bridge elements, stadium gradins, marine ecological modules, and solar farm foundations.

Product overview

Groupe GISONE is a family-owned concrete prefabrication company with over 50 years of experience serving public works, civil engineering, and building sectors. It operates two production sites (Auriol near Aubagne and Tarascon near Arles), employs 50 people, and produces 32,000 tonnes of concrete products annually with 2024 revenue of 10 million euros. The company offers a unified prefabricated concrete portfolio structured around eight core product families: Caniveaux (drainage channels), Réseaux secs (telecom/dry utility chambers), Voirie (road infrastructure), Regards (inspection chambers), Murs de soutènement (retaining walls), Produits RTE (electrical infrastructure), Génie Civil (custom civil engineering elements), and Préfa spéciale (custom special prefabrication). Standard product ranges are distributed through material traders across southern France, while custom civil engineering pieces are sold to major construction firms. The product family is unified by shared in-house capabilities — steel mould fabrication, concrete formulation, and reinforcement assembly — and the portfolio spans small standard components (chambers, curbs) to massive custom pieces up to 25 tonnes. Notable additions include ecological coastal protection modules promoting marine biodiversity and a low-carbon concrete range (23% carbon reduction) introduced in 2024.

Expansion highlights4 records

Broad incumbents

• Holcim (LafargeHolcim): Holcim is a global building materials giant with significant precast and concrete products operations across Europe. As a broad incumbent with extensive R&D and sustainability programs (including low-carbon concrete), Holcim competes with GISONE at the larger end of the French market and represents the long-term scale threat to niche precast specialists.
• Vicat: Vicat is a major French cement and ready-mix concrete group with operations spanning cement production, aggregates, and concrete products. As a broad incumbent in French construction materials, Vicat competes with GISONE indirectly through its concrete products division while also being a potential upstream cement supplier.

Direct peers

• Fabemi: Fabemi is a French family-owned manufacturer of concrete products including paving, retaining walls, drainage, and outdoor furniture. Comparable mid-sized French precast manufacturer with overlapping product categories in landscaping, public works, and building infrastructure served through distribution networks.
• KP1: KP1 is one of France's largest precast concrete manufacturers, producing floor systems, structural components, and prefabricated elements for residential and commercial construction. Like GISONE, KP1 serves the French construction market with standardized and custom precast products, but at a significantly larger national scale.
• Edycem: Edycem (part of the Edilians group) is a French precast concrete manufacturer producing structural and infrastructure elements including beams, slabs, and custom pieces. Comparable product portfolio targeting civil engineering and construction markets in France with similar B2B distribution to construction professionals.
• Stradal: Stradal is a French precast concrete manufacturer (part of CRH) producing elements for public works, civil engineering, and energy infrastructure including telecommunications chambers and grid components. Direct overlap with GISONE's réseaux secs, RTE products, and génie civil categories.
• Alkern: Alkern is a leading French manufacturer of precast concrete products including paving blocks, drainage channels, retaining walls, and structural elements. Operates a multi-site national footprint producing products that overlap directly with GISONE's standard TP range (caniveaux, murs de soutènement, voirie) at significantly larger scale.
• Bonna Sabla: Bonna Sabla is a French manufacturer specializing in precast concrete products for hydraulic, road, and civil engineering infrastructure, including drainage, retention, and structural elements. Highly comparable to GISONE's product lines (caniveaux, regards, murs de soutènement) with similar application focus on TP and civil engineering markets.
• Rector (Rector Lesage): Rector is a major French manufacturer of precast concrete beams, floors, and structural elements for the building and public works sectors. Both companies compete for French infrastructure and building prefabrication contracts with comparable product categories (beams, slabs, structural elements) and overlapping customer base among majors du BTP.

Emerging players

• Hoffmann Green Cement Technologies: Hoffmann Green is a French-listed company developing low-carbon and clinker-free cement formulations targeting the same ESG-driven procurement shift that GISONE's Béton Bas Carbone addresses. As an emerging competitor in sustainable concrete chemistry, it represents both a potential supplier and a formulation rival for low-carbon concrete market share.
