Sotrabat

What Sotrabat does

Sotrabat, legally SARL SO.TRA.BAT (SIRET 53790231400039), is a family-owned French small-to-medium enterprise headquartered at 31 Chemin de la Laiterie, 56270 Ploemeur, Morbihan. The company operates as a general structural-work and masonry contractor specializing in gros-oeuvre and pierre de taille, serving a 50km radius across the Morbihan and Finistère departments of southern Brittany. It is described as a PME with more than 40 years of operating history and holds Qualibat certifications n° 2111 (masonry and reinforced concrete with Patrimoine bâti / heritage buildings endorsement) and n° 2171 (stone cutting and installation), with all works covered by a decennial structural guarantee.

Sotrabat's core technical capabilities span new-house construction, extensions, building renovation, traditional stone cutting and installation (pierre de taille, pierre sèche), load-bearing wall openings, boundary walls, PMR accessibility modifications (ramps, elevator shafts), and specialized work including concrete patch repairs and carbon-lamella slab reinforcement. The firm does not deploy proprietary software, digital platforms, or AI tooling; its differentiation rests on craft know-how, heritage-stone expertise, and certified compliance rather than on technology differentiation. Marketing is limited to its sotrabat.net showcase website, earned local press (Ouest-France), and community sponsorships (CEP Lorient Basketball, Trophée Roses des Sables).

The business model is project-based: clients (individual homeowners, professionals, public organizations, and property management companies) initiate contact by phone, email, or web form; a mètreur (quantity surveyor) conducts an on-site visit for assessment and measurement; and a tailored quote is delivered. Revenue is one-time per contract, with disclosed individual project values ranging from roughly €157,000 to €1,060,000. Customer acquisition is sales-led and referral-driven within the local market, with no resellers, marketplaces, or digital channels.
