Definitions

  • the invention relates to a surface sealing element for buildings.
  • the entire outer surface of the building that is embedded in the water-bearing soil is sealed.
  • the structure is provided with surface sealing elements on its base and on its side walls and thus packed in a watertight manner.
  • the surface waterproofing must be carefully laid and welded in order to prevent water from penetrating.
  • Surface sealing elements are usually attached to the surface of the formwork wall facing the in-situ concrete and form a firm bond with the fresh concrete after pouring.
  • the surface sealing elements adhere to the outside of the concreted area after the shuttering has been removed and thus form a surface seal.
  • the EP 2 349 707 B1 discloses a surface seal consisting of a bulkhead layer, a composite layer and a sealant disposed discontinuously between the composite layer and bulkhead layer.
  • a flexible plastic film is used as the bulkhead layer, while a felt or fleece is used as the composite layer.
  • the sealant is a pressure sensitive or hot melt adhesive.
  • the fleece attached to the plastic film allows fresh concrete to partially penetrate.
  • the DE 692 13 507 T2 describes a surface seal with a carrier layer to which a pressure-sensitive adhesive layer is applied over the entire surface.
  • a fleece is arranged on the adhesive layer, which allows the fresh concrete to penetrate far enough to form a bond with the adhesive layer.
  • the surface sealing element has a flat carrier consisting of a plastic film and a textile layer arranged on the flat carrier, inseparably connected to the flat carrier and impregnated over the entire surface with a non-sticky adhesion promoter, whereby the textile layer can be a fleece .
  • the DE 40 01 386 A1 discloses a bituminous roofing membrane and a method for its manufacture.
  • the bituminous roofing membrane has a reinforcement layer made of thermoplastic fibers, it being possible for the reinforcement layer to be formed from a fleece.
  • the nonwoven or fabric membrane used as a reinforcement layer is first impregnated with a sizing solution, then passes through a dryer and is then fed to the roofing membrane manufacturing plant.
  • the reinforcement layer is then impregnated with bitumen, coated with bituminous covering compounds and finally laminated with foils.
  • the plastic sealing film consists of a structured film made of copolymer, the surface being structured and / or laminated with fabric or nonwovens.
  • the aim is to provide a surface sealing element for structures that is easy to handle and ensures that the structures are reliably sealed against water and moisture.
  • This object is achieved according to the invention by the surface sealing element according to independent claim 1. Further advantageous aspects, details and embodiments of the invention emerge from the dependent claims, the description and the drawings.
  • the present invention provides a surface sealing element for structures.
  • the surface sealing element has a planar carrier, the planar carrier being a plastic film, and a textile layer arranged on the planar carrier and inseparably connected to the planar carrier, the textile layer being a fleece.
  • the textile layer is fully impregnated with a non-sticky adhesion promoter.
  • the surface sealing element has a thickness I 1.5 mm.
  • the textile layer has knob-like elevations on its surface facing away from the flat carrier and / or the flat carrier has knob-like elevations on its surface facing away from the textile layer and / or the flat carrier has knob-shaped depressions on its surface facing away from the textile layer.
  • impregnating generally refers to an impregnating treatment of solid porous materials, such as e.g. B. textiles, paper, wood or concrete, understood with dissolved, emulsified or dispersed substances. Such dissolved, emulsified or dispersed substances are called impregnating agents. After the solvent or dispersion medium has evaporated or dried, the applied substances give the treated materials modified properties.
  • the surface sealing element according to the invention for structures has a textile layer which is impregnated over the entire surface with a non-sticky adhesion promoter.
  • a textile fabric is impregnated with an impregnating agent which contains a non-sticky adhesion promoter in the form of a solution, emulsion or dispersion.
  • the impregnation agent penetrates the textile fabric completely, so it penetrates into all pores, channels and openings of the textile. After the evaporation or drying of the Solvent or dispersion medium, the non-sticky adhesion promoter remains in the textile fabric or on all surfaces of the textile fabric.
  • Adhesion promoter is generally understood to mean a substance which, due to its properties, makes it possible to bond two materials which, due to their chemical composition, can only be bonded to one another very poorly due to their chemical composition or which are poorly bonded to one another under special environmental conditions can be connected.
  • Adhesion promoters create a bonding bridge between the material and the adhesive in materials or surfaces that are difficult to bond, or they improve adhesion if there are special requirements, such as B. high moisture / wet strength or temperature loads.
  • Adhesion promoters are used when different types of materials have to be glued together, which cannot be directly connected by an adhesive, or when a certain adhesive is to be used because of its special properties but does not adhere sufficiently well to one of the two adhesive partners.
  • a non-tacky adhesion promoter provided according to the invention provides a surface sealing element for building structures, the textile layer of which does not have any adhesive. For this reason, no further measures are required to protect the surface waterproofing during the construction phase. Even when the surface sealing is heavily loaded by workers moving on the textile surface of the surface sealing, the surface sealing is not damaged, since there is no, even short-term, sticking of e.g. Shoe soles can come with the surface sealing.
  • the textile layer can be made thinner and therefore more cost-effective. This is also due to the fact that there is no damage to the textile layer due to adhesions on the construction site.
  • the adhesion promoter also increases the surface area of the fibers of the textile layer, which means that more adhesive surface is available for the in-situ concrete, which at the same time improves the adhesion between fibers and concrete and thus between surface sealing element and concrete.
  • the surface sealing element according to the invention also shows very excellent properties in the sealing of structures against water and gas.
  • the planar support prevents gas and / or water from penetrating, so it is a substantially gas- and / or water-tight planar support.
  • the nonwovens used according to the invention as a textile layer are available at low prices, have the necessary flexibility and provide a large specific surface area to which the adhesion promoter can adhere.
  • the impregnation agent can pass through the very small openings in the fleece and, after drying, is available as an adhesion promoter on the surface facing away from the flat carrier for connection to the in-situ concrete. Since the textile layer is completely impregnated with the non-sticky adhesion promoter, adhesion promoter is available over the entire surface of the surface sealing element, which forms a bond with the fresh concrete when the in-situ concrete is poured.
  • the present invention provides surface sealing elements with a thickness of less than 1.5 mm and a laminated fleece.
  • the prior art does not know of such a thin sealing film which also provides the necessary rear-run security.
  • the textile layer is preferably a fleece made of polyester. Polyester fleeces are available at low prices and have particularly favorable properties in terms of flexibility and specific surface.
  • the textile layer has a mass per unit area of 20 g / m 2 to 70 g / m 2 , preferably 35 g / m 2 to 60 g / m 2 , particularly preferably around 50 g / m 2 .
  • a fleece with such a low mass per unit area and thus also a small thickness can improve the security of the surface seal from behind. The reason for this is that if a thin textile layer is used, the concrete can more easily penetrate to the flat support. This is what creates emergence prevents even the smallest cavities, so that there is subsequently no space for water to enter.
  • the flat carrier is a plastic film.
  • a plastic film fulfills the requirement of sufficient gas and water impermeability and advantageously has sufficient flexibility to enable the surface sealing element to roll.
  • the plastic film is preferably a plastic film consisting of polyvinyl chloride, polyethylene, polypropylene, propylene oxide, polyurethane, in particular thermoplastic polyurethane, or a thermoplastic elastomer based on olefin.
  • a plastic film made of the materials mentioned results in very good properties for the surface sealing element in the sealing of structures against water and gas. At the same time, a surface sealing element is obtained which has the flexibility required for rolling up. Tests have shown that a plastic film made of polypropylene as a flat carrier has the best properties with regard to preventing the penetration of gas and / or water.
  • a plastic film used as a flat carrier advantageously has a thickness of 300 ⁇ m to 1200 ⁇ m, preferably a thickness of 500 ⁇ m to 800 ⁇ m.
  • a plastic film of this thickness not only has sufficient gas and water impermeability but also has sufficient flexibility to enable the surface sealing element to roll.
  • the flat carrier preferably has a weight per unit area of 200 g / m 2 to 700 g / m 2 , particularly preferably 350 g / m 2 to 600 g / m 2 , particularly preferably around 500 g / m 2 .
  • a flat support made of the plastic polypropylene with a weight per unit area of 500 g / m 2 is most suitable.
  • a plastic dispersion, latex dispersion, resin, epoxy resin, crosslinkable synthetic resin, latex, latex emulsion, cement adhesive mortar, natural rubber, synthetic rubber, organofunctional silane, bitumen rubber, butyl is preferred as the impregnation agent for the textile fabric for the production of the surface sealing element - Rubber, bitumen or a deep primer, in particular a deep primer based on alkyd or acrylic resin, or used or an impregnating agent containing one or more of these materials.
  • the impregnating agents mentioned have been shown to be particularly suitable for impregnating the textile fabric.
  • the adhesion promoter contained in the impregnation agent lies evenly after drying distributed over the entire surface of the textile fabric and evenly distributed over the entire surface of the textile layer after the thermal bonding.
  • the surface sealing element preferably has a thickness I 1.2 mm.
  • adhesion promoters instead of the adhesives known from the prior art, it is possible to provide the textile layer of the surface sealing element with a smaller thickness, which is associated with the advantages already mentioned with regard to hindlimb security. Therefore, the entire surface sealing element can also be implemented with a smaller thickness, as a result of which material is saved, the required storage space is reduced and transport costs are reduced. These advantages become particularly evident when the surface sealing element has a thickness of I 1.2 mm.
  • the textile layer of the surface sealing element has knob-like elevations on its surface facing away from the flat carrier.
  • knobs By forming knobs on the top of the textile layer, its surface can also be enlarged, which leads to an improved connection to the in-situ concrete.
  • a mechanical bond with the fresh concrete is ensured by the knob-like elevations arranged on the surface of the textile layer facing away from the flat carrier.
  • the particularly good properties of such a surface sealing element are due to the fact that the surface sealing element simultaneously forms a mechanical bond and an adhesive bond with the fresh concrete.

  • the surface sealing element When used on the construction site, the surface sealing element is usually attached to a formwork wall, with the planar support of the surface sealing element being in contact with the formwork wall. Knob-like elevations on the upper side of the flat carrier result in a smaller contact surface with the formwork wall. When the surface sealing element is attached to the formwork, the surface sealing element is usually pulled over the formwork.
  • knob-like elevations In the case of knob-like elevations, the frictional forces that occur are not absorbed by the entire flat carrier, but essentially by the knob-like elevations.
  • the surface sealing element often adheres strongly to the formwork wall after the concrete has been poured. Due to the knob-like elevations, the contact area between Reduced formwork wall and surface sealing element, thereby making it easier to remove the formwork after the concrete has hardened. Lower forces therefore act on the surface sealing element, which prevents damage.
