ABSTRACT:
A generally T-shaped flexible spacer for use in the formation of a flexible joint in concrete cladding for pipes, having a base flange and a compressible web extending generally perpendicularly from the base flange on one side thereof. In use, spacers are applied to a pipe at intervals, and are self supporting with the web radial of the pipe. When concrete is sprayed onto the pipe it forms a cladding in sections, between which the spacers provide compressible joints to accommodate bending of the pipe.
