Abstract:
The invention relates to a lining element (10) for the rehabilitation of a pipeline, having a carrier layer (16) consisting of an expandable, resin-absorbent material which, in the longitudinal direction (L1, L2) of the carrier layer (16), has a first expansion rigidity, and a stiffening structure (24) which, in the longitudinal direction (L1, L2) of the carrier layer (16), has a second expansion rigidity, wherein the first expansion rigidity is lower than the second expansion rigidity and wherein the stiffening structure (24) is incorporated into the carrier layer (16).
