Abstract
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.
