This invention relates to a laminate for lining a passage, entirely or partially surrounded by walls, on or under the ground, comprising at least one layer of a reinforcement of continuous fibres, curable resin and a plastic foil or a plastic film, which is on the inside of the laminate when this one is introduced into the passage that shall be lined, there being arranged a fabric of fibres between the inner film and the reinforcement, which fabric on its side turned to the inner film carries cut fibres, and which together with its cut fibres form a combination fabric, absorbing resin, for concentration of curable resin to the inner surface of the cured laminate. According to the invention the laminate is characterized by the fact that the fabric (6) comprises at least two layers (8-10), put together, each one of which in an inactive position having two essentially parallel side portions (A, B), and which are displaced in relation to each other in such way that in an active position, i.e. when the side portions (A, B) are laid to a ring, there is formed a joint between the one side portion (A) of the one layer (8, 9) and the other end portion (B) of the other layer (9, 10), the remaining end portions (B, A) of the two layers (8, 9; 9, 10) are positioned in that way that they cover the joint on each side, and the joint arrangement making it possible for the end portions of the layers to be able to slide in relation to each other during the installation/expansion phase.
