Aslé conseil

What Aslé conseil does

Aslé conseil is a French technical study bureau (bureau d'étude) founded in 2013 by Gilles Martinet, specializing in diagnostic, analysis, and advisory services for mineral materials in built and movable heritage. The firm serves Architects in Chief of Historical Monuments (ACMH), heritage architects, public property owners (municipalities, ministries), private heritage owners, conservator-restorers, and historical monument restoration companies. Its work centers on diagnosing stone degradation, characterizing mortars/renders/concrete, and identifying pathogenic elements in monuments ranging from cathedrals and amphitheatres to archaeological sites and private heritage buildings. Operations span all of metropolitan France plus overseas territories (Saint-Pierre-et-Miquelon, La Réunion, Polynesia) and Tunisia.

The company's service portfolio comprises five core offerings: Diagnostic du patrimoine bâti (visual examination, pathology mapping, and diagnostic conclusions), Analyses en laboratoire (petrographic and petrophysical testing with research partners CTMNC, LRMH, and CICRP), Acquisition de données (drone photogrammetry via Panovues.com, non-destructive testing via GEOPAT, and manual sampling/coring), Assistance technique (technical assistance to ACMH, project owners, and restorers), and AMO (Assistance Maîtrise d'Ouvrage Patrimoine for project definition and programming). The firm emphasizes bespoke diagnostic approaches tailored per project rather than standardized solutions, with non-destructive investigation techniques that protect heritage structures during assessment.

Aslé conseil operates as a privately-held SAS (Société par Actions Simplifiée) with no disclosed external funding, generating revenue through quote-based professional consulting fees. The GTM is sales-led, relying on direct engagement with architects, heritage institutions, public clients, and private monument owners through professional networks, partnerships with heritage clusters (Pôle Culture & Patrimoines), scientific publications, and industry events. Since 2021 the team has expanded to include a second technical engineer (Alexis Texier, 2021), an administrative director (Lætitia Bertrand, 2022), a conservator-restorer collaborator (Célia Santi, 2024), and student interns. In 2024 the firm relocated its headquarters from Arles to Tarascon and created Aslé Conseil Grand Ouest, a wholly-owned regional entity based in La Rochelle to serve Atlantic-coast markets. Headcount remains in the 1-10 range; the firm is actively recruiting a materials engineer.

• SOCOTEC: Major French testing, inspection, and certification firm with heritage building diagnostic practices. Comparable as a provider of building-pathology and material-analysis services, though heritage is a sub-segment within a much wider TIC portfolio.

Direct peers
