The component comprises partly a support wall part (3) which supports an edge part of the higher ground area and partly concealed parts with a foot part (5), which is connected with an under part of the support wall part. The foot part is formed to rest on the ground approximately at the level of the lower ground area. The foot part has either an upwardly open recess or at a distance from the support wall part an upwardly directed projection (7). With a support wall formed by a number of adjacent components on the foot part top side is formed an upwardly open channel for receiving material (10) which holds the support wall components together. |
