A facing element (34) for use in a stabilized earth structure where the facing element comprises at least a hollow part (37) with an opening (36) on the rear face (32) wherein a cylindrical core (5) is arranged at least partly in the hollow part (37) and consists of two continuous parts (51, 52) where the first part (51) has a continuously decreasing size to an extremity (54) and the second part (52) has a continuously constant and/or decreasing size to an extremity (55) and wherein: L 2 ‰¥ 1.2 �¢ x d 1 ;
and A ‰¥ 0.24 �¢ x d 1 2 ;
wherein:
L 2 is the distance between the extremity (54) of the first part (51) and the rear face (32);
d 1 is the width of the cylindrical core (5) at the extremity (54) of the first part (51);
A is the area of the cross section of the cylindrical core (5) in the plane (X, Z). Improved anchoring properties are accordingly obtained.
