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.

GDS' apparatus assists ATC Williams NATA accredited soil and tailings laboratory to carry out complex monotonic and cyclic triaxial testings required for assessment of liquefaction.

To help UWA Engineering students gain exposure to laboratory tests as part of their studies in the current environment, David Reid and his team have been creating videos of different test procedures.  

GDS recently installed a temperature controlled Triaxial Testing System (ETAS) at the University of Nazarbayev, School Of Engineering and Digital Sciences in Kazakhstan.

SA Geolab International (SAGeo), are proud to launch the worlds most advanced portable laboratory. Situated in a 20ft DNV shipping container the laboratory can to be located anywhere in the world. 

SA Geolab International PL (SAGeo) based in Singapore, have recently announced the provision of a soil laboratory that can operate from 4°C to normal room temperature. This temperature range gives SAGeo the capability to carry out soil testing at in-situ temperature for deep water soil investigation. 

Clayton Dodd, Sales Director at GDS Instruments, recently visited the National Earthquake Engineering Research Center (NCREE) in Taiwan. The NCREE have recently installed a dedicated advanced dynamic testing laboratory at their new site in Tainan. GDS were chosen as the exclusive supplier for the laboratory and have installed Static, Dynamic, Shear and Resonant Column apparatus within the laboratory.

Diogo Teles a QA, Support and Installation Engineer from GDS Instruments, has recently returned from the University of Malta, where he installed an Enterprise Level Dynamic Triaxial Testing System (ELDYN), a 4MPa Triaxial Automated System (GDSTAS) and a High Pressure Triaxial Automated System (100kN / 64MPa / 100mm, HPTAS). High pressure LVDT’s and Acoustic Velocity Transducers have been purchased for the high pressure system. Whilst, Hall Effects, Bender Elements and LVDT’s have been procured to use on either the ELDYN or GDSTAS. 

When performing stability tests for the purpose of designing dams and deep excavations, an essential component is the appropriate selection of strength parameters of soils. Due to the fact that on the shear surface we deal with, the principal stress direction rotates, it is important to determine the strength parameters for the compression and the extension loading conditions.
