This invention relates to improvements in the control and stabilization of earthen or soil embankments comprising a gravity facing wall tied to and anchored by a grid or mesh extending into the embankment. The gravity facing wall is comprised of facing wall units or blocks stacked in overlapping horizontal courses. In particular an improved facing wall unit or block is provided featuring a projection formation extending longitudinally of the block in the upper surface and, in the lower surface, an offset recess of matching extent and configuration to the projection formation. The projection formation further includes grid or mesh engaging projections which penetrate the mesh or grid when registered thereover. A further recess or depression is also included in the upper surface of the facing wall unit or block and is of such an extent and configuration so as to confine therewithin the grid or mesh engaging projections and the grid or mesh when registered thereover.

La présente invention a trait à des améliorations apportées au contrôle et à la stabilisation des remblais en terre comprenant un mur de revêtement gravitaire attaché à un grillage ou treillis par le biais duquel il est ancré dans le remblai. Le mur de revêtement gravitaire est constitué de blocs ou éléments de revêtement se chevauchant en rangs horizontaux superposés. L'invention porte en particulier sur un bloc ou élément de revêtement qui comporte une formation de saillies sortant du bloc longitudinalement sur la surface supérieure et, sur la surface inférieure, un vide décalé de grandeur et forme correspondant à celles de la formation de saillies. La formation de saillies comprend en outre des saillies se mettant en prise sur le grillage ou treillis quand celui-ci y est placé en coïncidence. Un autre vide ou creux est également prévu dans la surface supérieure du bloc ou élément de revêtement et il est de grandeur et forme adaptées pour recevoir les saillies en prise sur le grillage ou treillis ainsi que le grillage ou treillis quand celui-ci y est placé en coïncidence.
