Borehole Extensometer



Borehole extensometers are used to measure movements of soil and rock along the the axis of a borehole. A wide range of extensometers is available, each designed for a particular application. In general, typical applications include:


  • Monitoring settlement or heave in excavations, foundations, dams, and embankments

  • Monitoring subsidence above mines, tunnels, and other underground openings

  • Monitoring convergence in tunnel walls and other underground openings

  • Monitoring movements in rock slides, walls, and abutments

  • Monitoring consolidation of soil under embankments and surcharges

  • Monitoring compression of piles and soil under piles
