Definitions

  • the invention relates to a composite sheet consisting of a bitumen sheet and an associated plastic layer, for installation between a bituminous layer and a hot applied layer based on bitumen or asphalt for waterproofing structures or bridges.
  • Moisture insulation is particularly important between structural parts of concrete structures and road surfaces.
  • the suitability of elastomer films for moisture insulation under poured asphalt is described in detail, for example, in the magazine “Bitumen, Teere, Asphalte, Peche”, Issue 4, 1972 pages 170 to 175.
  • a composite web for waterproofing structures between a first bitumen layer and the hot asphalt layer which may consist of a bitumen layer with glass fiber reinforcement and a film. It is provided here that the film surface is uneven in order to enable better adhesion to the asphalt layer and either a metal film or a plastic film, for example made of polyamide, is proposed as the film.
  • metal foils in road construction are known because they are attacked by de-icing salt and also act as a vapor barrier.
  • the latter is also the disadvantage of polyamide films according to DE-B-2 148 448 and elastomer films according to the article cited from “Bitumen, tars, asphalts, pitches” and DE-B-2 026 136, which act as a vapor barrier and thus in particular also form bubbles cause under the sealing layer.
  • the invention has for its object to provide a sealing layer for building waterproofing, which ensures a full surface connection of all layers, which is resistant to salt and avoids the formation of bubbles due to high vapor diffusion resistances.
  • a composite sheet is proposed to achieve the object, which is characterized by a plastic layer made of a reinforcing insert embedded in soft PVC based on glass fibers and which is bonded over the entire surface with a possibly multilayered bitumen sheet modified with polymers.
  • the plastic layer according to the invention made of a soft PVC layer with reinforcing insert ensures the sealing layer, at the same time it has a low vapor diffusion resistance, i.e. it is easy to diffuse and thus prevents the formation of blisters. Furthermore, it acts as a heat shield when the hot mastic asphalt is applied to the underlying bitumen membrane and still enables an adhesive full-surface bond with the asphalt layer.
  • An advantageous embodiment of the composite sheet according to the invention provides that a glass fiber mat, in particular glass fiber fleece with a basis weight of 30 to 150 g / m 2 is provided as the reinforcing insert of the plastic layer, which has a soft PVC mass with a ratio of PVC to plasticizer of 75 : 25 to 55:45 calculated in parts by weight, compactly impregnated.
  • a plastic layer has the desired low vapor diffusion resistance factor (measured according to DIN 53429), which is below about 7000.
  • Suitable plasticizers for the impregnation of the glass fiber mats are those listed in claim 3.
  • the soft PVC mass can also contain conventional stabilizers, pigments and auxiliaries. It is also possible to use other plasticizers that are compatible with PVC and suitable for sealing.
  • the plastic layer to be used for the composite sheet according to the invention advantageously has a glass fiber mat or fleece impregnated with soft PVC with a weight per unit area of 300 to 800 g / m 2 . In this configuration, they meet the conditions imposed on them when using structural waterproofing with the application of hot mastic asphalt.
  • bitumen welding sheet is preferably used as the bitumen sheet, which also contains a reinforcing insert, in particular a glass fiber mat such as glass fiber fabric or nonwoven with a weight per unit area of 30 to 200 g / m 2 .
  • the bitumen sheet preferably contains up to 50% by weight of polymers such as vulcanized or unvulcanized natural or synthetic rubbers, such as styrene-butadiene rubber, acrylonitrile-butadiene rubber, chloroprene rubber, butadiene rubber, isoprene rubber, butyl rubber, Ethylene-propylene rubber, ethylene-propylene-diene terpolymers, polyisobutylene, chlorinated polyethylene individually or in mixtures and, if appropriate, additionally conventional plasticizers and / or adhesives and / or polyolefins such as polybutene and / or fillers.
  • the bitumen sheets preferably have a thickness of 2 to 6 mm.
  • the composite sheet according to the invention is manufactured here in the factory, for example the glass fiber mat impregnated with soft PVC being laminated onto the bitumen sheet. This composite sheet produced in this way is then used on site for the waterproofing of the building.
  • a preferred use of the composite sheet according to the invention is used to produce a seal on buildings or Bridges used, z. B. a bitumen primer is applied from concrete, then the composite sheet with its bitumen sheet side is welded using heat, then the first mastic asphalt layer is applied to the plastic layer side of the composite sheet at the usual installation temperature of the mastic asphalt and then final layers are applied.
  • the overlapping seams are preferably also welded together.
  • a continuous full-surface sealing layer is created, which is also fully glued to the top and bottom of the adjacent layers, which creates the desired bond between the entire covering of buildings and bridges.
  • the composite sheet according to the invention even in its use or application, is absolutely resistant to de-icing salt and also has a low vapor diffusion resistance, so that bubbles are avoided under the sealing layer.
  • the composite sheet 1 is shown in cross-section, which consists of a bitumen sheet 4, modified and in particular weldable with polymers, which is laminated with a glass fiber mat 3 embedded in or impregnated with soft PVC 2.
  • FIG. 2 shows a building waterproofing using the composite sheet 1 according to the invention.
  • a bitumen primer 6 is applied to a substructure, the concrete layer 5.
  • the bitumen sheet side 4 of the composite sheet 1 is welded onto the bitumen primer 6, so that a full-area bond is produced.
  • the first poured asphalt layer 7 is then poured onto it, the soft PVC-impregnated glass fiber mat serving as a heat shield and at the same time forming a full-surface, adhesive bond with the asphalt layer 7.
  • the mastic asphalt layer 8 is then applied in the usual way, for example as a top layer.
  • FIG. 3 A bridge seal is shown in FIG. 3, the sealing layer with composite sheet 1 being built up under the poured asphalt layers 7 and 8 as in FIG. 2.
  • a further protective layer 10 is applied to concrete layers or in bridge construction under concrete caps above the composite sheet 1, for example from a bare bituminous cardboard R 500 N according to DIN 52 129 which is glued on by means of hot liquid bitumen adhesive in connection with a hot liquid bitumen top coat.
  • This area is additionally taped with a 7-10 cm wide self-adhesive, heat-resistant masking tape 12 on a plastic basis before the first poured asphalt layer is applied.
  • the purpose of the masking tape is to prevent the bitumen masses of the composite sheet 1 from swelling out of the covering area when the first poured asphalt layer is installed. In this phase, the bitumen of the composite sheet 1 heats up due to the installation temperature of the poured asphalt and can penetrate into it through the weight of the first poured asphalt layer.
  • the poured asphalt material would be changed in its material properties by additional bitumen.
  • the installation of the cover tape 11 according to the invention prevents this with certainty.
