Our laboratory provides a temperature-stable environment, and is equipped with the most modern soil testing instrumentation and equipment. Basic testing facilities, for example for liquid and plastic limits, compaction and oedometer compressibility testing, are complemented by apparatus for determining the most sophisticated of geotechnical parameters, using research-level testing techniques and equipment.

    Instrumentation
    Our advanced instrumentation can be used to achieve very high quality parameters to be used in your project. Non-standard tests are our speciality. We have some 20 years experience in designing and carrying out specialist testing for some of the largest and sensitive construction.
  • Internal load cells to prevent errors arising from ram friction
  • Extension top-caps to allow for the anisotropic consolidation/swelling and shear in     extension

  • Independent control of horizontal/vertical, total and effective stresses

  • Triaxial stages may under stress or strain control
  • High 'air-entry' (flushable) base pedestals and mid-plane probes (for accurate pore     water pressure measurement)

  • Local axial strain for measurement of very small strains (used for Young's modulus    determinations)

  • Local radial strain measurement when combined with local axial strain can be    used for bulk and shear modulus determinations

  • Shear wave velocity determinations through the use of bender elements. These     elements (mounted axially and/or radially) are used to provide the non-destructive     determinations of G at any stage during a stress path test.
