摘要：In a hollow construction at least partly embedded in the ground or surroundedby the ground for the transportation or storage of polluting substances, such as, forexample, in a drain channel, it is proposed to embed the wall of the hollow construction(2) in a sealing layer (3) of a non-setting mixture of mineral sealing materials, in particularclay materials such as, for example, montmorillonite, with the addition of mineralsubstances. In order to obtain as tight a storage of this layer as possible with a highsolids content and small pore volume, it is furthermore proposed to pre-mix in the drystate the materials forming the sealing layer and to insert them as a dry mixture; themoisture required for the effectiveness of the mixture as a sealing layer is supplied afterinsertion. By such embedding of the hollow construction, it is possible, for example insewage systems, to prevent polluting seepage water from being transported bothlongitudinally and transversely into the surrounding ground even at any damagedlocations possibly occurring, which seepage water escapes through these damagedlocations.
