Claim:
1. A repair assembly for repairing a substrate having a first planar surface and a second planar surface, the substrate having an imperfection or discontinuity in either the first planar surface or the second planar surface or in both the first and second planar surfaces, said repair assembly being a moulding assembly comprising a first mould member having a first planar portion for location against the first planar surface of the substrate, a second mould member having a second planar portion for location against the second planar surface of the substrate, and a connector interconnecting the first mould member and the second mould member to retain the first planar portion of the first mould member in contact with the first planar surface of the substrate and to retain the second planar portion of the second mould member in contact with the second planar surface of the substrate, said first mould member being located in spaced apart relationship to the second mould member to define a cavity therebetween formed by the first mould member, the second mould member and the imperfection or discontinuity, wherein the connector is hollow and is provided with an inlet for introducing a repair material into the cavity to repair the imperfection or discontinuity in the first surface or second surface or both the first and second surfaces of the substrate.
