ABSTRACT:
Voids in an artificial or natural structure are filled with a hardenable material in a liquid or semi-liquid state by surrounding the structure or a part of the structure containing the voids by a closely fitting, fluid-impermeable covering and sealing boundary edges of the covering to the structure to form a substantially fluid-tight enclosure. Air is evacuated from the voids within the fluid-tight enclosure and hardenable material in a liquid or semi-liquid state is allowed to enter into the evacuated voids until the hardenable material appears at the openings of the voids in the surface or surfaces of the structure. The hardenable material is then permitted or caused to set. The covering may be formed wholly or in part by at least one closely fitting, flexible, fluid-impermeable shroud, which is preferably transparent. At least part of the covering may comprise at least one closely fitting, fluid-impermeable coating.
