Various kinds of laboratory experiments were carried out on the Callovo-Oxfordian and Opalinus claystones to investigate response of clay rock to moisture change, including swelling and shrinking with variations of the environmental humidity, stress-bearing capability of bound porewater or buildup of swelling pressure, influence of water content on the mechanical stiffness and strength, and moisture-enhanced sealing of fractures. Significant responses of the claystones were observed.
