Applications

The CSIRO HI Cell is a proven, reliable and accurate instrument to determine triaxial stress in rock or concrete.

Common applications of HI Cells are for monitoring stress changes over time or determining orientation and magnitude of virgin stress by method of overcoring.

HI Cells are installed in metaliferous mines, coal mines, dams, tunnels, bridges, underground caverns, stroage facilities and other civil engineering projects.
