H. the concrete lining layer directly on the multi-layer sealing element with sufficient adhesion is possible. In this case, the sagging (quilt effect) of the sealing membrane, which is fastened at certain points, should also be avoided.
  • a multilayer plastic sealing membrane consisting of a waterproof layer and a water-permeable layer connected to the entire surface thereof, which is characterized in that the waterproof plastic membrane consists of two layers of soft PVC plastic, the first layer having a thickness of 0.5 to 3 mm is connected to the fastening means and a tangled fiber mat with a density between 15 and 35 kg / m 3 and a thickness of 5 to 25 mm is embedded in the second layer with a thickness of 0.5 to 2 mm, the rigidity of the seal is selected so that sagging is avoided with point-by-point attachment.
  • the tangled fiber mat in conjunction with the waterproof layer, represents a carrier adhesive layer for the concrete to be subsequently applied, in particular shotcrete, with which the interstices of the tangled fiber mat are filled.
  • the waterproof plastic layer and the tangled fiber mat form a mat that is still flexible, but with a limited stiffness that overcomes the dead weight within the point-by-point fastening areas, to which the shotcrete can be applied in a direct process without further aids, adheres to it and, after hardening, a firm one Lining base layer forms.
  • the actual lining made of concrete can then be applied to this layer in a direct coating process.
  • the sealing of walls against pressurized and seepage water is carried out using a multi-layer sealing membrane attached to the wall or a support layer applied to the wall and a lining layer made of concrete in such a way that the sealing membrane is punctually with its waterproof plastic layer side on the wall or Base layer is attached and the kill on the wall or base layer Tangled fiber mat arranged on the wall side is filled with a first lining layer as a primer made of shotcrete and a second lining layer made of concrete or the like is applied thereon.
  • the invention makes it possible to produce seals for walls, in particular made of natural rock, which carry leachate and / or pressurized water efficiently, with both the sealing functions, mechanical protection of the sealing sheet through a certain elasticity and adhesive carrier function for a shotcrete at the same time with only a two-layer sealing sheet be taken over.
  • the geomembrane has so much flexibility that it can be adapted to vaults etc. and still does not sag after being fastened in places.
  • At least partially plastic-coated disks are provided as fastening means, which are fastened to the wall by means of screws or the like, and which are welded or glued to the plastic sheet over the composite surfaces.
  • a tangled fiber mat made of polyamide threads or wires is preferably used for the multilayer sealing membrane.
  • resistant plastic material preferably polyamide, e.g. B. also polyolefins, such as polypropylene, constructed in such a way that a voluminous three-dimensional mat is formed with such spaces that they can be filled with shotcrete.
  • Such tangled fiber mats are known as single mats for erosion protection, whereby they are load-distributing in the ground and at the same time are porous and water-permeable.
  • they represent a combination sheet with a surprising effect for sealing with concrete lining.
  • the same plastic is preferably used for both plastic layers of the waterproof sheet, in particular soft PVC plastisol.
  • the tangled fiber mat can be embedded in the second layer of soft PVC plastisol in the ungelled state in a simple manner and anchored by gelling.
  • prefabricated plastic sheeting e.g. B. by calendering or extruding webs made of soft PVC with a further, the embedded embedding fiber mat receiving plastic layer.
  • Plastisols are understood to mean polyvinyl chloride pastes, i.e. H. PVC powder slurries in plasticizers without any added volatiles.
  • the main area of application of the multilayer waterproofing membrane according to the invention is the sealing of structures in natural stone, such as tunnels, tunnels, channels, which are sealed against pressurized and / or seepage water.
  • the rock 1 is shown in sections, the rough surface of which can be smoothed with a base layer 2 made of shotcrete. It is now necessary to provide a water pressure-maintaining seal between this wall and the actual lining of a tunnel or vault or gallery in the form of an inner shell, which usually consists of a correspondingly waterproof plastic film.
  • the two-layer sealing sheet 4, 9 is used so that the waterproof layer of plastic 4 comes to rest on the base layer 2 or in the absence of the base layer 2 on the rock 1, while the side of the sealing sheet formed by the tangled fiber mat 9 Interior of the building to be lined facing.
  • There are various methods of fastening the sealing membrane to the base layer 2 a point-by-point fastening is shown in the drawing.
