<p>A sleeper for a retaining wall is disclosed which comprises a recess to receive a projection means of a support post (e.g. a flange on an H-section). In this way, the projection means is covered by a tongue portion of the sleeper - this helps to hide the support post when the sleeper is viewed from one side. Sleepers are stacked between support posts to form the retaining wall.</p> |
