DESCRIPTION
ISO 22282-3:2012
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.
