Zusammenfassung:A waterproof sealing mat and a method of producing it are made available. The sealing mat is composed of a non-woven as supporting layer, an intermediate layer of expandable clay, preferably of sodium bentonite, and a covering layer which is preferably likewise composed of a non-woven, all three layers being sewn together in a needle loom in a conventional manner. When moistened, the bentonite swells and forms the waterproof layer. The waterproof sealing mat is used in particular in hydraulic and waste-disposal engineering.
