A method of encapsulating an item comprises the steps: (a) providing an open mould (38); (b) locating a former (36) within the mould; (c) filling the space between the mould and the former with a first batch of settable material (40), the volume of material being selected such that portions of the mould and the former remain clear of the material; (d) setting the material such that the set material defines a partially enclosed volume (43), as occupied by the former; (e) locating an item (20) at least partially within this volume; (f) filling the mould with a second batch of settable material (46) to encapsulate the item; and (g) setting the further batch of material. The item to be encapsulated may serve as the former or a part thereof and thus remain in the mould throughout the encapsulation process. Alternatively, part or all of the former may be removed after the first batch of material has set. <IMAGE> |
