Three areas of expertise, one team
We take on problems where the ground’s physics rules the design, and tackle them with high-level testing, modelling and engineering.
Multiphysical modelling
Coupled numerical models for rocks, soils and engineered barriers at specimen, full repository or reservoir scale.
- HM, TH and THM coupling, multiphase flow
- Advanced constitutive laws
- Calibration and uncertainty management
Geotechnical engineering
Design support where standard methods fall short, alongside your design team through every construction phase.
- Deep excavations and retaining systems
- Foundations and soil–structure interaction
- Soil dynamics, tunnels and shafts
Experimental geomechanics
Testing programmes, elaboration of procedures and laboratory coordination, with the modelling phase in mind.
- Triaxial, oedometric and creep testing
- Thermo-hydraulic and acoustic characterisation
- Multi-laboratory campaigns
An integrated, iterative workflow
Testing, modelling and design are not separate deliverables: each step informs the next, and field data closes the loop.
- 1
Understand
Review data, geometry and history.
- Geological and construction history
- In-situ data integration
- Conceptual model and governing coupled mechanisms
- 2
Characterise
Targeted testing where the model needs it.
- Testing programme defined by the model
- Our own tests or external laboratory coordination
- 3
Model
Coupled simulations, from screening to refined meshes.
- 2D / 3D coupled finite-element analyses
- Our own constitutive laws as subroutines
- 4
Advise
Clear, actionable recommendations.
- Sensitivity, optimisation and back analysis
- Design input and construction sequences
Iterative by design: monitoring and new test data feed back into the model
