This European Standard deals with the requirements, the basic performance criteria and evaluation of conformity for precast elements made of plain, reinforced or prestressed normal weight concrete, used for the construction of retaining walls. The products covered by this European Standard are intended to be used as part of retaining walls in applications such as: -- to retain natural ground excavations and trenches; -- to retain earth fills for roads, platforms, etc.; -- in bridge abutments and their flank walls; -- to retain several kinds of loose materials such as sand, gravel, etc. Some examples of precast elements considered in this European Standard are shown in the Informative Annex B. The products may be used in seismic areas on condition that they fulfil the requirements specific to this use.
