Abstract

For the purpose of fastening cables to the inner wall of a non-accessible waste-water pipe, an internal liner has been developed, which is constructed from at least two layers, the first layer, which rests against the internal wall of the pipe when in the laid condition, having a profile or empty spaces for receiving cables, and a second layer, of envelope-like type, which carries the first layer.
