Zusammenfassung:Water-impermeable and/or oil-impermeable bentonite sealing liners, which after laying provide a watertight and non-positive bond in the overlapping region (5, 5'), are provided. This is achieved by filling the pore space in the overlapping non-woven fabric layers (1, 2, 1', 2') with bentonite and subsequently needle-punching the overlapping region (5, 5') in situ or by means of bentonite-filled bitumen or plastics systems and subsequent adhesion bonding or welding of the overlapping regions. The overlapping non-woven fabric regions can also be fused together to form "films" and these regions then adhesion-bonded or welded.
