Definitions

  • the invention relates to a waterproof membrane, which is particularly suitable for use in building and civil engineering.
  • plastic films as a sealing material in such a way that the web-shaped films are applied overlapping to a substrate and a tape made of self-adhesive profiled sealing compound, for example made of butyl rubber, is placed between the films to connect the webs in the overlap area.
  • the adhesive tape required for this purpose is placed between two layers of a removable protective film, for example made of silicone paper, for the purpose of transport and handling when laying.
  • a removable protective film for example made of silicone paper
  • Plastic sealing sheets can also be welded using solvents or by heating.
  • a sealing membrane known from DE-GM 79 o7 342 consists of a bitumen layer which is covered on the underside with a non-woven material and on the top with sand, a bare, uncovered zone being provided for connection in the edge region. Heating is required to weld the sheets.
  • sealing materials consist of a flexible film with a coating of a self-adhesive sealant.
  • the preferred material for the sealant is a bitumen / rubber compound.
  • This material is also laid overlapping in layers in such a way that the self-adhesive sealant adheres to the surface to be sealed and is protected by the cover film.
  • the self-adhesive sealing compound of the upper sheet lies on the cover sheet of the lower sheet, so that bonding compound to sheet is achieved. If the membrane is not completely smooth, e.g. due to unevenness in the substrate, or if there is tension due to temperature fluctuations, incomplete bonding between the sealant and the film or the formation of capillaries through which water can penetrate can occur.
  • the invention is based on the object of developing a sealing membrane which not only has the advantages of the conventional materials, but moreover can be laid particularly conveniently and easily, and at the same time one provides completely waterproof layer.
  • a reliably tight, homogeneous connection is to be achieved in the overlap area of the sealing sheets, laying on substrates of all kinds should be possible, and application of further materials by adhesive bonding should not be ruled out.
  • the invention relates to a sealing membrane for use in building and civil engineering based on a plastic-elastic self-adhesive sealant and a flexible layer, which is characterized in that the sealant is enclosed between two flexible layers, the lower layer of the sealant in the region of a Long side and the upper layer does not cover the sealing compound in the area of the opposite long side and thus form a protrusion for the overlapping connection of the webs.
  • the upper layer in the area of one long side and the lower layer in the area of the other long side leave a narrow strip of the sealing compound as a fixing edge, which is arranged on the side opposite the overlap projection.
  • Bitumen / rubber mixtures are particularly suitable as sealing compounds, whereby their excellent temperature properties are important: They can be bent by 18o 0 to -30 ° C and show on the other hand no flow up to temperatures of + 80 ° C, ie sufficient stability. It is possible to lay the sealing membrane at temperatures around 0 ° C, since the self-adhesive properties of the sealing compound are then sufficient for a homogeneous connection.
  • a suitable sealing compound for the sealing membrane according to the invention consists, for example, of 40 to 80 parts by weight of bitumen (softening point 60 to 100 ° C. according to DIN 1995), 15 to 45 parts of aromatic oil and 5 to 15 parts of rubber, for example a styrene / butadiene copolymer.
  • the layer thickness for the self-adhesive sealant is between approximately 0.4 and 3 mm, preferably between 1 and 2 mm, in particular approximately 1.5 mm.
  • Suitable films are those made of polyvinyl chloride or fluoride, EPDM rubber, butyl rubber, chloroprene or natural rubber, i.e. Materials with sufficient elasticity that will not tear even with greater mechanical or thermal stress, but in particular polyolefin films, i.e. Films made of polyethylene or polyethylene / polypropylene, which can be stretched mono- or biaxially.
  • the thickness of the foils is between 4o and 5oo, preferably between 60 and 200, in particular around 100 ⁇ m.
  • two foils each with a thickness of 50 ⁇ m can be connected to one another.
  • Metal foils are also suitable for certain purposes, although they have a lower elasticity. Particularly favorable are metals, for example plastic foils vapor-coated with aluminum or copper, or laminated metal / plastic foils, for example made of an aluminum foil between two polyethylene foils. Such films are particularly characterized by their water vapor tightness, which makes them particularly suitable, for example, for use in cold store construction.
  • the sealing membrane according to the invention can also be constructed in such a way that the upper flexible layer consists of a film and the lower one consists of a non-woven fabric or a plastic film laminated with a non-woven fabric.
  • a sealing membrane is obtained which can be bonded to a substrate much better than a plastic film with the aid of adhesive, which can be particularly desirable if the sealing membranes cannot be weighed down after installation, for example with the aid of a gravel fill.
  • the lower flexible layer of the sealing membrane according to the invention consists of a mesh fabric, so that by pressing against the substrate it is possible to stick through (self-adhesive in places with the substrate). In all of these cases, in the seam or overlap area between the webs, the -homogeneous and tight connection is achieved in that one self-adhesive side area lies over another.
  • the sealing sheets according to the invention can be manufactured and used in different widths.
  • a favorable width is about 0.9 to 1.2 m.
  • the width of the self-adhesive area on the upper surface along one side and on the lower surface along the opposite side should be up to 10 cm, e.g. about 2 to 8, advantageously 4 to 7, but in particular about 7 to 8 cm.
  • the overlap area can have a smaller width because a particularly homogeneous and tight connection is achieved by the meeting of two areas with self-adhesive sealant.
  • the optionally provided fixing edge is normally much narrower than the opposite overhang for the overlapping connection of the webs.
  • the fixing edge accordingly preferably has a width of approximately 0.5 to 2, in particular approximately 1 cm.
  • the fixing edge is also covered with a protective film, for example a silicone paper. It is used to fix the sheets on the substrate without additional aids, which considerably simplifies the laying.
  • the an'der top lying F ix istsrand er adopted a set of subsequent layers, for example of fleeces or the like.
  • the sealing membrane is advantageously covered with a removable protective film, which is removed when the material is laid. Siliconized paper is preferably used for this.
  • the sealing sheet according to the invention made of self-adhesive, plastic-elastic sealing compound between two flexible layers, is characterized in particular by the fact that the upper layer floats to a certain extent on the lower one, which considerably promotes a compensation of mechanical or thermal stresses.
  • this material combines practically the advantageous properties of a simple plastic film and a plastic film coated with a sealing compound: It can also be installed where the direct application of bitumen or adhesive compounds, whether by pouring, brushing or in the form of bitumen - carrier films, is not possible; Compared to simple foils, the material has self-healing properties because the sealing compound itself closes holes in both cover foils, such as can occur when individual gravel stones pass through when laying the material.
  • the sealing membrane according to the invention with a self-adhesive sealing compound enclosed between two flexible layers can be produced in a particularly favorable manner in such a way that the two layer materials, e.g. Two foils are fed from above in a funnel shape, with a silicone paper strip being carried overlapping in a somewhat larger width in each edge region.
  • the sealing compound is placed in the funnel formed by the two supplied films and the silicone paper and the layer thickness of the sealing compound and at the same time that of the finished sealing membrane are controlled by the distance between the two rollers.
  • the area on the two long sides, which is used to glue the sealing membrane during the later overlapping laying, is obtained in that the film does not reach the edge on each side, but is replaced by the removable silicone paper.
  • the 1 consists of a self-adhesive sealant 11 between two films 12 and 13.
  • the upper film 12 does not extend to the long side 17, so that a strip of the self-adhesive sealant is exposed in the area of this side in the longitudinal direction.
  • the lower film 13 does not extend to the opposite longitudinal side 16, so that an exposed self-adhesive area is present in the area of this side on the underside.
  • the self-adhesive areas on both sides on the upper and lower surface of the waterproofing membrane are each covered with a removable protective film (e.g. made of silicone paper) 14 and 15, which are removed when the membranes are laid.
  • the protective film preferably protrudes slightly from the side so that it can be removed more easily.
  • the films 13 'and 12' opposite the films 12 and 13 leave a narrow strip 18, 19 of the sealing lug 11 free.
  • the fixing edge 19 on the underside causes adhesion to the substrate, while the fixing edge 18 on the upper side causes additional layers to be fixed.
  • the protective films 14, 15 prevent the material from sticking in the area of the fixing edges during transport and storage.
