Abstract:
1. A civil engineering work comprising: a front face, separating an upstream area from a facing, the facing rising from a substructure, said facing having a back surface and a front surface that is the same as said front face of the work, a fluid-tight covering arranged continuously on the whole back surface, a fill arranged behind said back surface and said fluid-tight covering, said fluid-tight covering being adapted to prevent fluids situated in the upstream area from penetrating into the fill, and said fluid-tight covering being protected from material adjacent to the front face, and at least one anchoring device ensuring a mechanical linkage between the facing and the fill, wherein said facing comprises at least one cavity inside of which a first portion of the fluid-tight covering is arranged to form a fluid-tight recessed space into which is inserted an anchoring element that is a part of said anchoring device, and the cavity and the recessed space are configured to allow mechanically anchoring the anchoring device in the facing, the cavity having at least one mouth, wherein said fluid-tight covering comprises a second portion formed as a flat sealing plate adjacent to the back surface of the facing, and said first portion of the fluid-tight covering forming the recessed space is a sealing member following an inner shape of said cavity, the sealing member having a flat connecting surface encircling the cavity mouth, said flat sealing plate and said connecting surface of the sealing member being connected in a fluid-tight manner by a seal.
