Disclosed is a device for containing granular elements, comprising a metal mesh panel having metal wires welded together, the panel comprising at least one curvature of a first orientation and at least one curvature of a second orientation, the first orientation being characterized by a first axis and the second orientation being characterized by a second axis, the first axis and the second axis being non-collinear.

Device for containing granular elements

A void former is arranged in a mold (). The void former includes an insert () made of flexible material that forms a loop around a core region () within the mold. Casting material is added in a fluid state into the mold so as to fill a predefined volume for the facing element, including the core region. After hardening of the casting material, the facing element () is removed from the mold, and the void former is removed from the facing element. The facing element comprises an anchoring core formed by the hardened casting material in the core region (). Removing the void former comprises pulling the insert () away from a rear surface of the facing element (). The flexible material of the at least one insert is deformed around the anchoring core () while it is pulled.
