A facing system for a frictionally stabilised earth structure comprises an assembly of facing units (1) each having a sloping facing panel (3) with a substantially horizontal upper edge and a lower edge situated rearward of said upper edge and substantially parallel thereto, the facing panel being supported by a pair of laterally spaced side panels (2). The facing units (1) are assembled to form a series of superimposed substantially horizontal tiers wherein the sloping facing panels (3) in said tiers are laterally spaced and are positioned vertically above corresponding lateral spaces between facing panels in the tier below, whereby earth (9) immediately behind said structure in contact with said facing panels, forms an open sloping surface (10) from the lower edge of each facing panel through the space in the tier immediately below to the upper edge of the facing panel vertically below said space, the slope of said surface being less than the angle of repose of the earth. The side panels (2) on each side of each said facing panel (3) restrain lateral movement of the earth of said slope and are provided with means (7) for attachment to frictional stabilising members embedded in the earth of said structure. |
