A grout pack assembly (1 ) is provided which includes one or more grout bags (2) which are inflatable with a settable granular material or grout, and a plurality of restraining rings (20) which are shaped to extend circumferentially about the grout bags in a vertically spaced arrangement to provide support against lateral deformation of the inflated grout bags. The restraining rings are formed by at least two arcs (30) joined through joints (34) about which such ring may be collapsed or dismantled. The joints may be provided by interlinked loops (36). |
