What CORROHM does

CORROHM is a French corrosion engineering consultancy founded in 2020 and headquartered in Vieille-Toulouse, France, operating with a 4-person team of PhD-level corrosion specialists (three of whom hold N3 Béton certification from CEFRACOR). The company delivers expert corrosion diagnostics, durability assessments, and cathodic protection design for reinforced concrete and metallic infrastructure across the construction and civil engineering value chain. Its core technology stack combines a proprietary on-site diagnostic device (CMAP) with a 3D electrochemical digital twin built on COMSOL Multiphysics, enabling interpretation of field measurements, prediction of residual service life, and design of cathodic protection systems compliant with European standard EN ISO 12696. Supporting capabilities include laboratory analyses (SEM/MEB, X-ray diffraction/DRX, chloride titration) and a bespoke chloride threshold determination protocol based on galvanic coupling between contaminated concrete cores and passive reference specimens. The company is publicly positioning itself as a pioneer of Computer-Aided Design (CAO) tools for corrosion engineering under the 'corrosion engineering 2.0' framing.

Revenue is generated through project-based professional services engagements priced via quotes following a free initial consultation, with no publicly disclosed price points. The go-to-market is expert-led and consultative, combining content marketing (technical blog, scientific publications, conference participation such as Eurocorr 2022) with direct enterprise field sales targeting infrastructure owners, engineering firms (Tractebel, Oxand), construction companies (BTPS Atlantique, Soletanche-Freyssinet), and heritage preservation clients. Engagement models span diagnostic campaigns, pathology expert reports, design of corrosion maintenance strategies, and ongoing intelligent monitoring of cathodic protection installations. Customer segments are horizontal across infrastructure owner-operators, architects/engineers, and construction firms, with notable international reference projects including the Mohammed VI Tower (O'Tower) in Rabat, Morocco, and the Le Corbusier water tower in Podensac, France. R&D activity is anchored by the CORROMER project, a BPI France DeepTech-funded (€90k) initiative targeting maritime structure corrosion, supported by institutional partners including INSA Toulouse, LMDC, CNRS, and Paul Sabatier University.

Core offering

CORROHM provides expert corrosion engineering services for concrete, reinforced concrete, and metal structures, combining on-site diagnostics, laboratory analysis, 3D numerical simulation (digital twin), and cathodic protection system design. The offering is built around a proprietary CMAP diagnostic device and a digital twin platform that interprets field measurements, predicts residual service life, designs optimized maintenance solutions, and enables intelligent monitoring of cathodic protection installations validated against European standard EN ISO 12696.

Product overview

CORROHM offers a unified suite of corrosion engineering services for concrete, reinforced concrete, and metal structures (immersed or buried). The core offering is built around its proprietary CMAP diagnostic device and a 3D numerical simulation / digital twin platform, which underpin all service lines: Diagnostic Expert, Durability Study, Maintenance Strategy, Optimized Cathodic Protection Design, and Instrumentation & Monitoring. The company also provides laboratory analyses (chloride dosage) and is developing new technologies through its CORROMER R&D project targeting maritime structures.
