GDS are excited to launch their new range of hydraulic load frames for soil & rock testing. The range is available from 100kN to 1.5MN, encompassing our latest design and technology.

Marine soft clay with weak engineering properties, is widely distributed in Southeast China. As the most developed area in China, Zhejiang has a vast transportation infrastructure including highways, roads, railways and airport runways which have been constructed on the marine clay. With long-term vehicle loading, excess settlement tends to occur on the existing infrastructure. In order to reveal these effects on the marine clay caused by vehicle loading, and to predict future settlement, research was undertaken by Wenzhou University.

GDS held a coffee and cake fund raiser this month, with over £150 being donated to Macmillan Cancer Support. The morning included a cake making competition which, was won by Jeff Gray from our design team. Well done Jeff and all those who contributed to the morning.

September has been a month of exhibitions for GDS. With exhibitions in Australia, Germany and France, read how the team got on below.

The stress path test is commonly used to simulate the changing mechanical properties of soils, whilst under varying stresses. Research in this area, within China and abroad has gradually increased. The static triaxial apparatus based on the Bishop Wesley principle is widely accepted. However, in reality, the stress change of soil is usually accompanied by changes in the environment.

Take advantage of the weak pound! Since June, the pound has dropped over 10% in value against the Dollar & EURO. Resulting in favorable pricing for our international customers.

The Tuaheni Landslide Complex (TLC) is  located on the upper slope of the Hikurangi Margin, off the East Coast of the North Island,  New Zealand. They have developed novel laboratory-based testing  using gravity core samples from within the TLC and a Dynamic Back-Pressured Shearbox  (DBPSB) from GDS Instruments to replicate offshore slope conditions.

The quantity of land affected in the extraction of lignite in opencast mines is vast. Former mining activities leave behind numerous mine voids, which will mostly remain as artificial lakes. Overburden dumps are stretched over large areas. These areas present themselves as often uninhabitable and difficult areas for construction without further site investigation and understanding mostly remain as artificial lakes from rising groundwater and flooding.
