Soil Laboratory
A unique facility dedicated to the study of soil corrosion and the assessment of protection systems for buried pipelines and structures
| Parameter | Capacity |
|---|---|
| Temperature | 4–90 °C |
| Media | Natural soils, synthetic soils, marine sediments, polluted/recycled soils |
| Gas | Dissolved oxygen control (Air/N₂/CO₂) |
| Water content | Capillary soil cells with stable water content |
| Parametric study | Chlorides, sulphates, water content, resistivity, cyclic humidity... |
Available facilities
- Exposure cells under constant or cyclic water content
- Differential aeration corrosion assessment setup
- Soil library (natural and synthetic soils)
- On-site exposure in France and across the EU with remote monitoring
- Cathodic disbondment cells in soil
- Soil characterisation: resistivity (tellurometer, soil box), pH, thermobalance, chlorides, sulphates, pH buffer
- Custom ER corrosion sensors (all grades)
- Real-time monitoring: corrosion potential, redox potential, water content, galvanic coupling, corrosion rate
- Stabilised polarisation curves on a cathodic protection witness
- Addition of potentially corrosive microorganisms and microbiological assessment (in partnership with Corrodys)
- Finite element modelling (COMSOL Multiphysics): distribution of currents and potentials, interference phenomena and stray currents
