Materials laboratory

Our laboratories in the Lyon region (France) are configured and equipped to deliver effective answers to issues around Materials and Special Paints and Coatings.

Our technicians and engineers provide their expertise to support the diagnosis, expert appraisal and recognition of structures, to characterise and study the behaviour of materials as part of providing our clients with assistance and technical advice that aligns as closely as possible with the problems they experience.

Types of analysis and testing

Chemical analyses and the physical and mechanical characterisation of construction materials, paints and coatings.
Petrographic and microstructural characterisation:
observation at different magnifications (using binocular loupes and optical, polarising and scanning electron microscopes)
Research and study of concrete and masonry pathologies
Qualitative and quantitative mineralogical analysis
Identification and concentration of pollutants
Qualification, performance and ageing tests
Expert appraisal and diagnostics
Identification of fault causes, nature and extent
Identification of durability parameters
Interpretation of results, conclusions, advice and expert recommendation
