An anti-spalling edging comprising a metal strip (21, 31) having a return (22, 32) along a top edge and a down-turn (22, 33) from the return (22, 32), spaced from the strip. The down-turn (23, 33) is provided with cut-outs (24, 34) for anchoring the edging in concrete, with the cut- outs (24, 34) being arranged to provide faces against which the concrete abuts when cast level with the outer surface of the return (22, 32). In use the anti-spalling edging may be provided on a joint (1) between two concrete slabs (S2, S3). As such a pair on anti-spalling edgings will be provided, the two metal strips abutting with the returns (22, 32) extending in opposite directions on lay of the concrete. The joint (1) can include dowels (6) extending into the two sections of concrete for vertical load transfer in use. |
