ROCK TESTING

Our modern laboratories boast the latest in technology with regards to testing, including:
 

• Rock sawing facilities for core preparation

• Precision end face grinder allowing machining of both core faces simultaneously

• Two Compression machines for rock UCS testing

• Extensometers allowing Young’s Modulus and Poisson’s Ratio to be integrated with UCS testing

• 100mm Direct shear units with electronic data acquisition, with maximum confining pressures of 1600 kPa
