As part of the advance laboratory testing program for Fundao Mine Tailings Dam Failure, KCB’s Vancouver Geotechnical Laboratory used GDS Instruments' EMDSS device to perform direct simple shear tests in order to obtain undrained peak and large strain shear strengths on monotonic simple direct shear tests; undrained response to cyclic loading on cyclic simple shear tests; and undrained response to cyclic loading on cyclic simple shear test with static bias.

In February 2019, GDS completed the installation of a Large Diameter Cyclic Triaxial Testing System at the University of South Carolina. The system was purchased to expand the laboratory capability to tests ballast samples with diameter of 150mm and 300mm.

GDS’s Dynamic Pressure Controller (SIG3) is a dynamic pump for the precise & rapid regulation and measurement of fluid pressure and volume change.

Its great to see some GDS apparatus feature in KCB recent post on the history of their geotechnical laboratories.

Following local investment in 2018 to establish an advanced tailings laboratory in Johannesburg, Golder partnered with the University of the Witwatersrand to provide students with learning opportunities and promote better collaboration between academia and the industry. 

In February, GDS completed the installation of their Large Diameter Cyclic Triaxial Testing System at BGC Engineering Inc (BGC) New Advanced Geotechnical Laboratory in Fredericton, Canada

Trilab Pty Ltd has just taken delivery of a new Cyclic Direct Simple Shear machine. This will compliment their existing Critical State Triaxial testing equipment. The simple shear is currently being used on a major tailings testing project.

GEOTEKO have recently increased their testing capacity with the addition of more apparatus. 

Their state-of-the-art facility offers world class geotechnical testing of soil and rock for a variety of applications. Given that the current global pandemic has made visiting their new lab challenging, they have organised a virtual tour, follow the link in their article.
