Method of manufacturing a facing element for a reinforced soil structure

A method of manufacturing a facing element for a reinforced soil structure, the method comprising:

• arranging a void former in a mold, the void former including at least one insert made of flexible material, wherein the at least one insert forms a loop around a core region within the mold;
• adding casting material in a fluid state into the mold such that the casting material fills a predefined volume for the facing element, the predefined volume including the core region;
• letting the casting material harden to form the facing element;
• and
• removing the facing element from the mold and the void former from the facing element,
• wherein the facing element comprises an anchoring core formed by the hardened casting material in the core region,
• and wherein removing the void former comprises pulling the at least one insert away from a rear surface of the facing element, the flexible material of the at least one insert being deformed around the anchoring core while it is pulled.
