Abstract: A liner hose for use in the reconstruction of damaged buried conduits or pipelines, in particular sewers, comprises inner and outer layers of liquid-tight plastic film material and a number of substantially uniform intermediate layers composed at least partially of a fibrous material impregnated with a curable resin. Each intermediate layer is formed from a strip, which is substantially unstretchable in any direction and has a width such as to enable folding of the strip into a closed hose structure with unbonded seamless overlapping. The overlap sections of all intermediate layers are located with mutual separation in the same side of the liner in its folded condition.
