|GDS Instruments triaxial cells were the choice of Trilab, and are currently used for the 2,000 triaxial tests performed each year within Trilabs laboratory. "Trilab prefers GDS triaxial cells due to their high machining precision, which is especially noticeable in the gliding operation of the internal ram" says Gavin Hamilton, Chairman.
GDS‟s range of triaxial cells include traditional load frame based triaxial cells, Bishop and Wesley Stress Path and high pressure triaxial cells, all of which can cater for a range of different sized specimens and pressure ranges.
GDS also manufacture bespoke triaxial cells upon request.
Trilab‟s 18 triaxial units are used to measure the shear strength of soil and rock specimens, to aid in the engineering design associated with mining and infrastructure projects, including open-cut mine pitslope design, slope stability assessments of dams and road cuttings, and foundation design for buildings and bridges. The triaxial cells can also be used for measuring the 'permeability' of soil and rock, which represents the rate of fluid infiltration. Trilab have 4 additional triaxial units dedicated to permeability testing.
