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.
