Description
Voidage at the interface between the bentonite and EDZ would lead to a connected transport path along the contact region. Any such voidage is, however, likely to close due to the plasticity of the Opalinus Clay and the swelling of the bentonite, and seals are designed to prevent flow and advective transport along any such path.
