Visit from National University of Singapore

7th December

Professor Harianto from NUS and Professor Ken Mercer visited EPLabs  on the 7th of December to undertake a tour of the laboratories Unsaturated Soil Testing Facilities. Machines and technology for these testing machines are at the forefront of modern day Soil Mechanics, specifically designed to test soils in its natural or remoulded state (natural or specific moisture content).

ACG Unsaturated Soil Mining Seminar

ACG Unsaturated Soil Mining Seminar


3rd December 2014
 
EPlabs in association with the ACG (Australian Centre for Geomechanics) held a 3 day event on Unsaturated Soil Mechanics in Mining Seminar at the UWA Club House. Phil from EPLab presented on the Laboratory Testing Techniques in Unsaturated Soil Mechanics to various companies that attended on the day.

To better accommodate the requirements and improve accuracy and efficiency for soil and rock testing


To better accommodate the requirements and improve accuracy and efficiency for soil and rock testing.

we have acquired an extra six (6) specially designed Soil Triaxial Machines (max confining pressure of 3MPa) that can conduct anisotropic consolidation testing, stress path testing and the normal CU, CD and UU tests.

We have also acquired one (1) new tailored designed Servo-Controlled Direct Shear unit that better facilitates direct shear requirements for both open defects (structures) or intact shearing.
 
The other two (2) newly designed machines acquired are for the state of the art unsaturated soil mechanics. Machines can perform unsaturated direct shear testing also pressure plate testing to obtain the SWCC curve required for air-entry value analysis and suction matric analysis.
