Definitions

  • the invention relates to a waterproofing membrane for use in construction, with a flexible plastic layer made of in particular thermoplastic or thermoelastic, weldable or adhesive plastic and with one on at least one Side of the plastic layer laminated substrate layer, in particular from a Reinforcement material, wherein a longitudinal edge of the substrate or reinforcement layer of an adjacent longitudinal edge of the plastic layer has a distance, so that the Plastic is exposed in an edge strip of the web.
  • Such waterproofing membranes are used in particular for sealing roofs Joints and used by tunnels etc.
  • Synthetic fibers, e.g. Polyester, polyamide or polypropylene, or natural fibers, such as e.g. Glass, rock, tree, cellulose, etc. are suitable as materials for the waterproofing membrane especially PVC, polyethylene, polypropylene and other polymers or copolymers or mixtures. Thermoplastics can be welded.
  • Cross-linked plastics are glued or e.g. welded by ultrasound.
  • the substrate layer can in particular to reinforce or improve the bonding of the Web on a surface, as a separating layer against migration, as a cushion layer or serve to improve the insulating properties.
  • the object of the invention is to reduce the risk of such a failure.
  • This weakening is avoided in the sealing membrane according to the invention by that the substrate layer in an edge region adjacent to the said longitudinal edge has a gradually decreasing thickness against this longitudinal edge.
  • the tapered substrate edge area also prevents or reduces if the application is not precisely fitting, sharp transitions or larger cavities in the existing substrate composites in the joining area. Partial overlap of the tapered Substrate area on the connecting track are possible and lead to a smooth transition.
  • the sealing membrane shown has a flexible plastic layer 1 made of a thermoplastic or thermoelastic, weldable and adhesive plastic.
  • a reinforcing substrate layer 2 is laminated onto one side of the plastic layer 1. This can, for example, be made from a fleece or a woven fabric or mesh from synthetic or natural fibers.
  • the plastic layer 1 usually has a thickness d1 from 0.5 to 4 mm, and the substrate layer, in particular a nonwoven, can expediently have a thickness d2 of 1 to 4 mm.
  • a longitudinal edge 2.1 of the reinforcing material layer 2 has an adjacent one Longitudinal edge 1.1 of the plastic layer 1 a distance b, so that the weldable Plastic of layer 1 is exposed in an edge strip 1.2.
  • This strip 1.2 can the use of the waterproofing membrane with the plastic layer of an adjacent one Sealing membrane is welded overlapping, e.g. by heat and / or swelling and / or Solvent ( Figure 2).
  • the width b of the edge strip 1.2 can be expedient about 2 to 5% of the total width B of the waterproofing membrane.
  • the total width B is usually in the range of 1.5 for roofing membranes or membranes for earth waterproofing to 2.5 m, preferably about 2 m, and the width b of the edge strip can then in Range from 4 to 10 cm.
  • the longitudinal edge 2.1 of the reinforcing layer with an edge in the plastic layer is pressed in and weakens it has the reinforcing layer 2 in an edge region 2.2 adjacent to the longitudinal edge 2.1, one against the longitudinal edge 2.1 gradually decreasing thickness.
  • the thickness can preferably be down to zero leak.
  • the edge region 2.2 of the reinforcing layer can expediently be a Have width a, which is equal to 0.5 to 5% of the total width A of the reinforcing layer.
  • the edge area 2.2 can also, as indicated in FIG. 2 with broken lines, a bit below the plastic layer of the neighboring waterproofing membrane extend.
  • the sealing membrane described is used in construction, especially for Sealing roofs, tunnels, wall columns for flooring work and the like.
