Carrières de l'Ouest

What Carrières de l'Ouest does

Carrières de l'Ouest is a privately held French aggregate extraction and production company founded in 1858, operating as an independent entity within the Groupe Basaltes conglomerate and led by PDG Thomas Dupuy d'Angeac. The company runs 14 extraction sites between Brittany and Pays de la Loire — including the flagship Voutré quarry, the specialty La Heslière sand deposit, and the Brittany-Normandy Carrière de Beaucé — together with three processing platforms (MATSUD, MATTOURS, St Mars la Brière) and two Île-de-France distribution nodes at Bonneuil-sur-Marne and Trappes. Its product portfolio covers construction sand, gravel, crushed stone (graves), recycled aggregates, large rocks for port/coastal engineering, and specialty turf sand for professional sports venues.

The business operates a vertically integrated model combining extraction, in-house crushing and processing, a wholly owned transport and rail subsidiary (Cinérites Transport et Logistique), and a ready-mix concrete subsidiary (Béton Tavano). Its signature logistics asset is the Voutré Double Fret system, launched in 2021 with SNCF Réseau, which delivers aggregates by rail to Paris platforms while returning construction debris to rehabilitate extraction sites — saving an estimated 25,000 km of truck transport per train per day and supporting both cost efficiency and ESG positioning.

Commercial activity spans direct sales to construction professionals (terrassement, voirie, réseaux, béton), individual homeowners, and public-sector clients, with materials sold in bulk or big bags with daily delivery. Recent landmark projects include 40,000 tonnes for the Versailles equestrian course (Paris 2024 Olympics, via GL Events), 30,000 tonnes for the A4 highway (Colas), and supply to PSG's Poissy training center and the Clairefontaine national team facility. Active expansion into Île-de-France, ongoing acquisitions (Sablière de Fercé-sur-Sarthe from Lafarge in 2023, majority stake in Orbello Baglione in 2025), and the planned Villeneuve-Saint-Georges platform indicate a deliberate strategy to consolidate the western French aggregates market.

Direct peers

• Groupe Pigeon: Family-owned French aggregates, concrete and road construction group headquartered in Brittany. Highly comparable in footprint (Grand Ouest), product mix (sand, gravel, ready-mix concrete) and customer base (B2B construction professionals).
• Sablières de la Seine: French sand and gravel extraction specialist with operations in the Paris Basin. Comparable because it targets the same Île-de-France supply chain that CDO is now entering via Bonneuil-sur-Marne and the planned Villeneuve-Saint-Georges platform.
• Carrières du Boulonnais: Independent French quarry operator producing construction aggregates, sands and gravels in northern France. Comparable mid-sized, vertically integrated aggregates peer with similar mix of extraction, processing and inland distribution.
• GSM (Heidelberg Materials France): Leading French aggregates-only specialist with nationwide quarry footprint and recycled materials activity. Closely comparable operating model — extraction, crushing, distribution of sand, gravel and crushed stone, plus recycling of C&D debris for similar end-markets.

Broad incumbents

• Eurovia (VINCI Construction): VINCI's road and aggregates subsidiary operating a large French quarry and recycling network. Comparable in producing and supplying crushed stone, gravel and recycled aggregates for public works and infrastructure projects across France.
• Lafarge (Holcim France): France's largest aggregates, cement and ready-mix producer with nationwide quarry networks. Comparable because CDO acquired Fercé-sur-Sarthe directly from Lafarge Granulats; directly competitive in sand, gravel and recycled aggregate supply to construction markets.
• Colas (Bouygues): World-leading road construction group with significant aggregates and recycling operations in France. Comparable because Colas is both a customer of CDO (30,000 t for A4) and a competitor supplying its own quarry network to road-building contractors.
• Eiffage Route: Eiffage's road construction and aggregates arm, producing and consuming its own crushed stone, gravel and recycled asphalt. Comparable as a vertically integrated competitor supplying the same public works and road infrastructure tenders in France.
• Vicat: Major French cement and aggregates group with vertically integrated concrete operations. Comparable because Béton Tavano (CDO subsidiary) competes head-on with Vicat's ready-mix business for the same B2B construction customers in western France.
• Cemex France: Global cement, ready-mix and aggregates player with French quarry operations. Comparable as a producer of crushed stone and recycled aggregates supplying construction and infrastructure projects, often competing for the same tendered volumes.
