Abstract
A covering for a containment pool, tank or enclosure, in particular a containment enclosure for a nuclear power plant, is produced by placing metal sheets parallel to a first wall at a predetermined distance from the latter, each sheet comprising anchoring elements, on a first face arranged facing the first wall, placing a rail situated between the anchoring elements and comprising side walls and a base delineating a space facing the area to be welded with two adjacent sheets, making a weld bead by full-penetration butt welding of the adjacent metal sheets, and pouring concrete between said first wall and the metal sheets, the anchoring elements of the metal sheets being completely independent from the weld bead after the concrete has been poured.
