Abstract (en)
[origin: WO2007054350A1] The invention relates to a flexible insert tube (1) for the lining of pipelines (2) and of ducts, in particular of sewers (4), where the flexible insert tube (1) has at least two sublayers (8, 10, 22), of which at least one first sublayer (8, 12) has fibres composed of an inorganic material and can be impregnated by a hardenable reactive composition, characterized in that in the direction from the inside to the outside, based on a longitudinal axis (6) of the flexible insert tube (1), a first inner sublayer (8) is followed by a further sublayer (10), which can be impregnated by the hardenable reactive composition, and whose proportion of fibres composed of an inorganic material is less than 100%.
