A seal may be made between an object 2 such as a cable, cable splice or branch-off, and a surface 4 such as a recoverable sleeve by means of a flexible envelope 8 containing a void-filling composition 10, 12. The void-filling composition undergoes a change from low viscosity on installation, which allows the envelope 8 to conform to the object 2, to high viscosity after installation, which gives mechanical strenght to the seal, Deformation of the flexible envelope 8 on installation may be brought about by installation of the recoverable sleeve or other surrounding surface 4. |
