ABSTRACT:
A process for production of cut-off walls, characterized by the fact that a geotextile-smectite mat that contains a water-swellable smectite is introduced to a not yet hydraulically set cut-off wall composition.
A further object of the invention is a geotextile-smectite mat in web form, characterized by the fact that it contains a sealing layer of water-swellable smectite between two geotextile layers and has a locking mechanism on each side edge for tight joining of the web to another web that has a complementary locking mechanism on each side edge.
