Abstract Preview

ISO 22282-3:2012 specifies the requirements for water pressures tests (WPT) carried out in boreholes drilled into rock as part of geotechnical investigation and testing according to EN 1997-1 and EN 1997-2.

The tests are used to investigate the following:

  • hydraulic properties of the rock mass, which are mainly governed by discontinuities;
  • absorption capacity of the rock mass;
  • tightness of the rock mass;
  • effectiveness of grouting;
  • geomechanical behaviour, e.g. hydrofracturing, hydrojacking.
