A parallelepiped structure (10) comprises interleaved panels (12), each panel being moulded from concrete and being rectangular in plan and comprising a plurality of slots (22) along their top edges (16). The panels can be interleaved in order to provide the structure (10). Tongues (13) between adjacent slots (22) are supported on both sides against movement perpendicular to the plane of the panel (12) by ridges (24a,b) on the supporting panel, and so that the weakness inevitably constituted by them is mitigated. The structure (10) is suitable to accept vehicular loading, while the panels that make it up are still individually light enough to be manipulated by hand. The panels are moulded in moulds assembled from blow-or vacuum-moulded sheets placed together in a sandwich. |
