Laboratory Testing
Soil, rock and materials laboratory testing is performed in our Naas laboratories under the direction of experienced and qualified technicians. Tests are undertaken in accordance with the relevant British Standards (BS), European Standard (ES) and International Society for Rock Mechanics (ISRM).
Our soils capability testing includes the following:
- Moisture Content
- Liquid & Plastic Limits
- Particle Size Distribution
- CBR
- Compaction (2.5/4.5/Vib hammer)
- MCV
- Undrained & Drained Triaxials
- Consolidation
- Shear Box
- Permeability (triaxial cell method)
- pH
- Sulfate
- Chloride
- Resistivity
Routine rock testing is carried out in Naas, with specialist testing by associated UK and Norwegian laboratories. Rock testing capability includes:
