Definitions
- the invention is based on a watertight membrane comprising a Schott layer and a composite layer, which on one side of the
- Schott layer is arranged, according to the preamble of the first claim.
- the invention is further based on a molded part comprising a waterproof membrane, a waterproof molding and a method for sealing substrates.
- Composite layer is not completely interspersed with applied concrete. All of this can lead to cavities through which liquids can spread. In the case of a leak in the bulkhead layer, for example by growing roots, material fatigue or by train or
- Object of the present invention is therefore to provide a waterproof
- the advantages of the invention can be seen in the fact that the sealant between the composite layer and the Schott layer hinders, or respectively prevents, the penetration of the Schott layer in the case of a leak in the Schott layer.
- voids that form between concrete mixed composite layer and Schott layer are interrupted by the sealant. This restricts the size of the areas trapped by the infiltrated water. The damage caused by the infiltrated water is thereby limited to a smaller area and the damage point makes it easier for you to locate. This is particularly advantageous, for example, for repairing the damaged area with a crack injection.
- the sealant is arranged like a grid.
- Such a grid-like arrangement is advantageous in that it creates a plurality of grid cells, each of which is enclosed by sealing means.
- the sealant along the grid cell would make it difficult to spread outside the grid cell, the subsequent grid cells further complicate the spread of the liquid, in particular prevent.
- sealant partially penetrates into the composite layer. As a result, cavities in the composite layer, through which liquids can spread, are interrupted by the sealant.
- FIG. 1 shows a cross section through a Schott layer connected to a composite layer of the prior art.
- Fig. 2 cross-sections through waterproof membranes before adding liquid concrete to the composite layer.
- Fig. 3 cross sections through waterproof membranes connected to concrete. The sealant inhibits the spread of penetrated

- Fig. 7 perspective schematic representation of a waterproof molding.
- FIG. 1 shows a cross section through a Schott layer connected to a composite layer of the prior art.
- the peeling of the composite layer from the bulkhead layer or incomplete penetration of the composite layer with concrete can lead to voids along the bulkhead layer.
- penetrating water can traverse the bulkhead layer over large areas through coherent cavities. If one of these cavities is connected to a crack in the concrete layer, the penetrated water can penetrate the concrete through this crack. In this case, the exit point of the water does not allow conclusions about the location of the leak.
- the invention is waterproof

- sealant 4 all materials are suitable, which are suitable to reduce the passage of liquids 10, in particular of water, by mentioned cavities 11 along the bulkhead layer 2, respectively, to prevent. Further, it is advantageous that the sealant 4 in the alkaline pH range, in particular due to the concrete 7, is stable and can perform its sealing function. Further, it is advantageous if the sealant has a high resistance to possible additives of the penetrating liquid 10 in the case of a leak 9 in the Schott layer 2. Such additives are typically salts, especially in groundwater containing salt water, calcium hydroxide, sulfur-containing compounds and solvents.
- the sealant 4 is a thermoplastic or a thermoplastic elastomer.
- Thermoplastic elastomers have the advantage that the sealing agent thereby has good elasticity with respect to horizontal and vertical displacements, in particular displacements of the bulkhead layer 2 and composite layer 3. A good elasticity of the sealant prevents cracking or detachment of the sealant and thus a failure of the seal.
- thermoplastic elastomers in this document are understood as meaning plastics which combine the mechanical properties of vulcanized elastomers with the processability of thermoplastics.
- thermoplastic elastomers are block copolymers with hard and soft segments or so-called polymer alloys with correspondingly thermoplastic and elastomeric constituents.
- thermoplastics and thermoplastic elastomers are in particular selected from the group consisting of polyethylene (PE), low density polyethylene (LDPE), ethylene / vinyl acetate copolymer (EVA), polybutene (PB); olefin-based thermoplastic elastomers (TPE-O, TPO) such as ethylene-propylene-diene / polypropylene copolymers; crosslinked olefin-based thermoplastic elastomers (TPE-V, TPV); thermoplastic polyurethanes (TPE-U, TPU) such as TPU with aromatic hard segments and polyester soft segments (TPU-ARES), soft polyether segments (TPU-ARET), Polyester and polyether soft segments (TPU-AREE) or polycarbonate soft segments (TPU-ARCE); thermoplastic copolyesters (TPE-E, TPC) such as TPC with polyester Weichsegme ⁇ ten (TPC-ES), soft polyether segments (TPC-ET) or with polyester and polyether soft
- Preferred acrylate compounds are in particular acrylate compounds based on acrylic monomers, in particular of acrylic and methacrylic esters.
- polyurethane polymer encompasses all polymers which are prepared by the so-called diisocyanate-polyaddition process, including those polymers which are almost or completely free of urethane groups.

- the sealant 4 is a pressure-sensitive adhesive and / or a hotmelt adhesive. This ensures a good bond and good adhesion of the sealant on the Schott layer 2, respectively on the
- Pressure-sensitive adhesives and hot melt adhesives are generally known to the person skilled in the art and are described in CD Römpp Chemie Lexikon, Version 1.0, Georg Thieme Verlag, Stuttgart.
- the sealant 4 contains swelling substances which increase their volume to a multiple upon contact with water, typically between 200 - 1000% of the original volume.
- certain swelling substances can also react chemically with water.
- swelling agents are polyurethane-based bulking agents, in particular silane-modified polymers which cure by moisture to give an elastic product.
- swelling substances are bentonite-butyl rubbers.
- the swelling substances are swelling substances which react with water in a time-delayed manner by coating, so that the swelling substances do not swell or only slightly during contact with moist concrete, and in particular in the case of running behind the waterproof membrane 1 with liquid 10 Water, remain swellable.
- the sealant 4 can be pressed more strongly against the Schott layer 2 and / or mixed with concrete composite layer 8, in addition cavities 1 1 are reduced by the volume expansion of the swelling substance. Both contribute to reduce the passage of water through cavities 1 1 along the bulkhead layer 2, in particular to prevent.
- the sealant 4 is arranged in a surface structure and / or lattice-like.
- Such a surface structure is illustrated, for example, in Figures 4a and 4e, in which context the term "surface structure” is understood to mean the arrangement and formation of the material in the space and not the surface condition of the material.
- the advantage of an arrangement in a surface structure is, on the one hand, that the production is simpler, in particular if the individual surfaces are uniformly arranged and have the same shape and surface area. ensures a good bond and good adhesion of the sealant 4 on the Schott layer 2, respectively on the composite layer 3, which in turn reduces the risk of detachment of the sealant 4 and thus a failure of the seal.
- a grid-like arrangement of the sealant 4, wherein the sealant forms the grid lines 12, is shown for example in Figures 4b, 4c and 4d.
- the grid-like arrangement may or may not be structured.
- a lattice-like arrangement, in particular a structured lattice-like arrangement is advantageous in that, compared to an arrangement in a surface structure, less sealant 4 is required as a result.
- Another advantage is that the grid-like arrangement a plurality of grid cells 13 is provided, each of which is enclosed by sealing means 4. In the case of the penetration of liquid 10 into such a grid cell 13, the sealant 4 along the grid cell 13 would complicate the spread outside the grid cell, in particular prevent, the subsequent grid cells further complicate the spread of the liquid 10, in particular prevent. This is shown by way of example in FIG. 5, wherein the density of the hatching corresponds to the quantity of liquid 10 that has penetrated.
- the sealing means 4 may partially, as shown in Figure 2b, or completely penetrate into the composite layer 3, as shown in Figure 2c, in particular when the composite layer 3 is a porous material.
- the sealant 4 can not penetrate into the composite layer 3, as shown in Figure 2a.
- the composite layer 3 has a greater thickness than the sealant 4.
- the sealant does not completely penetrate the thickness of the composite layer, which may have the advantage in that the sealing agent does not reach the surface of the side of the composite layer 3 facing away from the Schott layer 2.
- Such sealant 4 especially if it is a permanently tacky sealant, may be detrimental to rolling up and unrolling the waterproof membranes 1, transporting and walking on the watertight membranes prior to application of the concrete 7.
- the sealing means 4 can penetrate 0-80%, preferably 5-50%, in particular 10-30%, of the thickness of the composite layer 3.

This can be done in particular by the fact that in the production of the waterproof membrane 1, the composite layer 3 and the Schott layer 2 are directly connected to each other by heat, by pressure, by physical absorption or by any other physical force. This has the particular advantage that no chemical bonding of the Schott layer and the composite layer by means of adhesives is necessary, which has an advantageous effect on the production costs of the waterproof membrane 1.
- the composite layer and the Schott layer can be connected to one another by laminating. Lamination can achieve a strong bond between the composite layer, especially if it is a nonwoven, and the Schott layer.
- the composite quality in the production of waterproof Lamination membranes are more reliably and less subject to variations in production parameters than adhesive bonding.
