摘要

A method (M1) for making non-woven fabric sheet (I) for use as a reinforcement or stiffener in a flexible sealing membrane, involves (a) forming the fabric from natural fibres (preferably plant fibres), possibly with a small amount of thermoplastic or thermofusible fibres, by mechanical, pneumatic or hydraulic lay-up, (b) consolidating the fabric by needling followed by bonding with a chemical binder or by heating (preferably under pressure) and (c) water-proofing the fabric. Independent claims are also included for (1) a method (M2) for the production of flexible sealing membranes by coating or priming (I) with a sealing binder on a coating line or an impregnation line, or by calendering (2) non-woven sheet (I) obtained by M1 (3) prefabricated flexible sealing membranes obtained by coating or impregnating (I) with a sealing binder .
