Void former assembly for casting facing elements for reinforced earth. Anchoring recesses are cast into its rear face so that earth-reinforcing strips can be looped through. The anchoring recesses are each formed as a loop channel having a convex inner surface and a concave outer surface, at least one of which has a radius of curvature which increases from the deepest part of the recess towards the rear face. A removable void former assembly and method for casting such facing elements are also described. Because of the varying radius of curvature of the surfaces of the channel, and the rotational and translational withdrawal path of the void formers, the channel can be cast deeper, and with openings which are closer together, than has hitherto been possible using removable void formers.

Retaining wall

The present invention concerns a method of installing a reinforcement strip in a compacted fill retained by facing element together with the reinforcement strip extending between an anchorage zone and the wall. The anchorage zone is located away from the facing element and separated from the facing element. The method comprises: a) installing the reinforcement strip in the fill by feeding the strip from a first location in the anchorage zone to the wall and looping the strip through a wall connection point back to a second location in the anchorage zone; b) tensioning the strip by pulling the strip to a predetermined tension at the first location and at the second location; and c) anchoring the strip to the fill at the first location and at the second location while keeping the strip under tension.
