Реферат: A sealing mat for use in civil engineering for insulating soil with respect to liquids, in particular water, is proposed. Said mat has two outer layers which consist of fibre material and between which a powder, consisting of mineral sealing material, e.g. bentonite, is introduced, and the two layers are connected to each other. An aerated non-woven (3), into which the powder (4) consisting of mineral sealing material is incorporated, is introduced between the two layers (1, 2), and the two layers (1, 2) with the aerated non-woven (3) located therebetween are sewn to each other. <IMAGE>
