One of the significant changes in PN-EN 206:2014 as an amendment of the PN-EN 206-1:2003 is Annex D, which formulates additional requirements for specification and compliance of concrete for special geotechnical works. The article presents these requirements in the field of other applicable documents and the current way for ensuring the sustainability of concrete in the ground environment. Ground is a specific environment and the use of concrete (and reinforced concrete) elements due to special chemical conditions, humidity and temperature. Elements listed in Annex D are extremely important because of its function in the structure and hard-to-repair characteristic and basically non-exchangeability. Therefore, in this case the concept of durability should be treated more widely including considerations of resistance, and more clearly said – reliability (robustness). It means that the element should provide (or only slightly reduce) the usability, even in the event of changes in the conditions of serviceability, and the possible effects of destruction should not be to an extent disproportionate to the cause.
