A sealing member for sealing over an aperture in a surface. The member comprises a flange formed from a resilient material for sealing against the surface around the aperture in the surface. A strengthening member supports the flange. A retaining portion formed from the resilient material is provided on an outside surface of the strengthening member to secure the strengthening member to the flange. The retaining portion is integrally formed with the flange via a through hole in the strengthening member.

1. A sealing member for sealing over an aperture in a surface comprising: a flange formed from a resilient material for sealing against the surface around the aperture in the surface, a strengthening member for supporting the flange the strengthening member comprising a number of parts assembled together around the flange, each part comprising a through hole adjacent to, and through, each end of each part and a retaining portion formed from the resilient material on an outside surface of the strengthening member for securing the strengthening member to the flange, the retaining portion integrally formed with the flange via the through hole, and wherein the retaining portion covers ends of adjacent parts of the strengthening member. 2. A sealing member as claimed in claim 1 wherein the retaining portion is integrally formed with the flange via two or more through holes in the strengthening member. 3. A sealing member as claimed in claim 1 wherein the sealing member comprises a plurality of retaining portions spaced apart around the flange on an outside surface of the strengthening member, the plurality of retaining portions integrally formed with the flange via a corresponding plurality of through holes in the strengthening member. 4. A sealing member as claimed in claim 3 wherein one or more said retaining portions is integrally formed with the flange via two or more through holes in the strengthening member. 5. A sealing member as claimed in claim 1 wherein the sealing member comprises apertures for receiving fasteners for securing the sealing member to the surface, and wherein one or more said apertures is in a said retaining portion and extends through or is aligned with a corresponding through hole in the strengthening member, in use the retaining portion forming a resilient washer for a head of a fastener received through a said aperture. 6. A sealing member as claimed in claim 5 wherein the apertures for receiving fasteners are closed apertures, in use the fastener piercing the closed aperture. 7. A sealing member as claimed in claim 5 wherein the through hole and the aperture for receiving a fastener have different shaped cross sections, the aperture fitting within the through hole. 8. A sealing member as claimed in claim 7 wherein a lateral dimension of the aperture for receiving a fastener is equal to a lateral dimension of the through hole. 9. A method as claimed in claim 7 wherein the through hole has a polygon shaped cross section. 10. A sealing member as claimed in claim 1 wherein the retaining portion extends beyond an edge of the strengthening member on a base of the sealing member. 11. A sealing member as claimed in claim 1 wherein: the separate parts do not overlap, and/oreach said part corresponds with a side of the flange, and/oreach separate part is a strip of material, and/orthe separate parts are dimensionally the same, and/orthe separate parts are arranged on the flange end to end, and/ortwo adjacent parts butt together, and/ora gap is provided between two adjacent parts and filled with the resilient material. 12. A sealing member as claimed in claim 11 wherein the ends of two adjacent parts are mitred together in a mitre joint at a corner of the flange, and wherein a flange aperture is formed at a corner of the flange at the mitre joint, and a portion of said flange aperture formed in an end of each of said two adjacent parts. 13. A sealing member as claimed in claim 1 wherein the sealing member is a blanking plate for sealing around and blanking off the aperture in the surface, or wherein the sealing member is a sealing gland for sealing between an elongate member extending through the aperture in the surface and the surface around the aperture, the sealing member comprising:a base comprising the flange, and a skirt extending from the base for receiving and sealing around a periphery of a said elongate member. 14. A sealing member for sealing between a surface and an elongate member extending through an aperture in the surface, the sealing member comprising: a base for forming a seal with the surface or for providing a flashing to make the surface watertight around the aperture,a circumferential up-stand extending from the base for receiving the elongate member, the up-stand comprising a through hole,a skirt formed from a resilient material moulded to an outer surface of the up-stand for receiving and sealing around a periphery of said elongate member, anda retaining portion formed from the resilient material on an inner side of the up-stand for securing the skirt to the up-stand, the retaining portion integrally formed with the skirt via the through hole. 15. A sealing member as claimed in claim 14 wherein the retaining portion is integrally formed with the skirt via two or more through holes in the up-stand. 16. A sealing member as claimed in claim 14 wherein the sealing member comprises a plurality of retaining portions spaced apart around the up-stand integrally formed with the skirt via a corresponding plurality of through holes in the up-stand, or wherein the retaining portion is a continuous circumferential bead on the inner side of the up-stand integrally formed with the skirt via a plurality of said through holes spaced circumferentially apart around the up-stand. 17. A sealing member as claimed in claim 14 wherein the base and up-stand are integrally formed from sheet material. 18. A sealing member as claimed in claim 14 wherein the retaining portion covers an upper end of the up-stand on an inside surface of the up-stand to be joined with an inside surface of the skirt. 19. A sealing member for sealing over an aperture in a surface comprising: a flange formed from a resilient material for sealing against the surface around the aperture in the surface,a strengthening member for supporting the flange, the strengthening member comprising a through hole, anda retaining portion formed from the resilient material on an outside surface of the strengthening member for securing the strengthening member to the flange, the retaining portion integrally formed with the flange via the through hole, andwherein the strengthening member comprises a number of parts assembled together around the flange, the ends of two adjacent parts mitred together in a mitre joint at a corner of the flange, and wherein a flange aperture is formed at a corner of the flange at the mitre joint, a portion of said flange aperture formed in an end of each of said two adjacent parts.
