Short summary
Under German law, crack damage stress must not be reached at any time during the operation or post-closure phase of a nuclear waste repository. This legal requirement can only be fulfilled if the parameter can be measured precisely. We have thus developed a new measurement technique, which overcomes the limitations of the conventional method. In combination, old and new methods offer an easy procedure to detect crack damage stress in fully saturated rocks in a fast and robust manner.
