An inclined retaining wall for retaining and securing the slope of an inclined piece of terrain comprises a plurality of horizontal rows of prism-shaped elements, which rows of elements are superimposed one upon the other in a relationship staggered rearwardly in upward direction. The elements of each row are spaced relative to one another leaving gaps therebetween, and a base at the foot of said inclined piece of terrain supports a lowermost row of the elements. Each element of a superimposed one of the said rows bridges a corresponding gap in the next adjacent row therebeneath and is aligned in an inclined series with an element in any second row therebeneath or thereabove. Some or all elements have a hollow soil-fillable interior open at the top end and at the bottom end of such element, whereby plants planted in the soil at the open top end of one of these elements can extend their roots through the open bottom end of that element into the soil therebeneath. These elements are usable in upright position in the retaining wall, each element comprising a casing having a hollow soil-fillable interior open at the top end and the bottom end of the element, a front wall of the casing being destined to face away from the slope, side walls and a rear wall, and rampart means on the face of the rim of the open top end being positioned centrally on the said front wall of the element. |
