The wall includes two spaced shells or panels (2,3) with a gap between. At the top of the gap is at least one filling opening into which heavy bulk material can be introduced, e.g. gravel. Material (13) can be emptied selectively from the gap through at least one outlet opening (5). - The or each outlet opening is provided in one of the shells and is closed by a pivotal door (6). The door extends from adjacent the shell lower edge upwardly through e.g. one of fifth of the wall height. Bulk material is emptied from the gap to facilitate transportation of the building. |
