Abstract of the Disclosure Water- and/or oil-tight bentonite sealing sheets or mats are produced which after laying have a water-tight and frictional interconnection or join in the overlapped part thereof. This is achieved by filling the pore space in the overlapped zone with bentonite and following in situ needle punching of the overlapped zone or with bitumen or synthetic resin systems, optionally filled with bentonite, and later bonding or welding of the overlapped zone. It is also possible to weld the overlapped zone together as "films" and then to bond or weld such zones.
