YieldPoint adapted its world renowned dExto extensometer for installations in soils. YieldPoint’s soil extensometer has higher profile anchor points and adjustable resistance to extension. The anchor points can be position to extend or contract.

The YieldPoint d-Civil-Exto comes coiled and pre-assembled and read to install. A successful road settlement monitoring project calls for a rapid and economical installation, high survivability, high performance in soft soil materials, individual instrument tracking for large systems, easy transportability and handling.


  • Small head allows recess into borehole 
  • Small head allows muliple extensomters to be decked in the same borhole.
  • 6 anchor points are standard
  • Simpler, faster installation leading to less traffic disruption. 
  • reduced human error
  • Installed quickly from Minimal laydown area 
  • reduced procedural steps and field cutting and assembly of components will greatly reduce potential assembly errors providing a more reliable solution.
  • Readings directly in real worl units reduces human error.

YieldPoint dEXTOs have proven, best in class, water immunity.
