Geotechnical Instrumentation

Harrison offers a range of geotechnical monitoring services to complement in-situ and laboratory testing and computer modelling. Monitoring can help ensure structural safety and to develop economical designs.

Geotechnical instrumentation is installed in boreholes, in the ground or within structures and includes:

  • Piezometers to measure ground water level or pressure
  • Inclinometers to measure ground displacement
  • Borehole extensometers to measure movement along the borehole axis
  • Vibrating wire settlement gauges to measure settlement or heave
  • Digital hydrostatic profile gauges to measure the horizontal and vertical rotation of ground and structures and the heave and shrinkage of clay soils. They can also be used to monitor the short and long term effects of imposed loads.
