Rock Mechanics and Physics Laboratory
51 Science Facilities — Engineering and Geotechnical Capability
The Rock Mechanics and Physics Laboratory (RMPL) undertakes research on the properties and behaviour of rocks and geomaterials at near-surface to shallow crustal depth for georesources (energy; storage), geoengineering (tunnelling) and geohazards (faults; earthquakes).
Beneath our feet, rocks continuously deform, slide and move differently across a large spectrum of environmental conditions (pressure; temperature; fluid chemistry, etc.) and time — very slowly in creep mode for instance, or very rapidly during an earthquake. These coupled processes take place at all scales, from atomic level mineral/fluid interfaces to continental faults, mostly at inaccessible, deep locations precluding direct observations.
Laboratory capabilities
RMPL is the home of BGS large-scale rock deformation apparatus and specialises in standard (ISRM and ASTM) and bespoke geomechanical and rock physics testing.

- Deformability
- Thermal properties
- Geophysical properties
- Permeability
- Porosity
- Density
Equipment
