Definitions

• the present invention relates to a method for producing water-sealed wall surfaces from cement-based materials, in particular walls of reinforced concrete structures, to a method for producing water-sealed floor surfaces from cement-based materials, in particular floors of reinforced concrete structures, and a method of making water-sealed surfaces from cement-based materials, particularly overhead surfaces.
• the water can come into contact with the surfaces both directly and indirectly through, for example, soil that is contaminated with the water.
• Plastic waterproofing membranes are known for sealing the surface of concrete structures made of a HDPE waterproofing membrane, a pressure-sensitive adhesive layer, a weather-resistant acrylic coating or a layer of bitumen, or a layer of a mixture of bitumen and plastic and a removable protective film.
• a protective film When the protective film is peeled off and then applied fresh concrete, resulting in the hardening of the fresh concrete a continuous solid compound (an adhesive bond) between the adhesive layer and the concrete, which should be permanently prevented from water leakage. Since in the construction of the concrete structure, the protective film must be removed quite early, because a later removal is no longer possible because of the applied reinforcement, the adhesive layer is impaired with the additional weather-resistant coating in its effect as a primer because it pollutes in the period thereafter and can be damaged.
• the present invention is therefore based on the object to provide a surface seal with rear run protection, the uncomplicated and only shortly before z. B. the concreting can be applied.
• this object is achieved according to a first aspect by a method for the underfloor-proof production of water-sealed wall surfaces of cement-based materials, in particular walls of structures made of reinforced concrete, comprising: building an outer formwork, preferably full-surface application of a sealing material on the inside of the outer formwork Placing a reinforcement in front of the inside of the outer formwork provided with the sealing material, applying a bonding agent to the sealing material through the reinforcement, constructing an inner formwork, filling a cement based material in the formwork cavity formed by the outer and inner formwork, and allowing the material to harden forming a strong bond between the sealant on the sealant material and the cement based material.
• the cement-based material in the process described herein is preferably unreinforced or reinforced concrete, such as reinforced concrete or prestressed concrete, shotcrete, but also mortar or screed.
• the wall surfaces can extend both vertically and at an angle 0 to the vertical.
• this object is achieved according to the invention by a method for the back-safe production of water-sealed floor surfaces of cement-based materials, in particular floors of structures made of reinforced concrete, comprising: preferably full-surface application of a sealing material to a stable substrate, in particular a cleanliness layer, preferably made of unreinforced concrete, arranging a reinforcement above the layer of the sealing material, applying a bonding agent on the sealing material through the reinforcement, installation z. B. casting cement-based material from above into a formwork erected before or after placing the reinforcement (28) around the subsurface, and allowing the material to set to form a strong bond between the adhesive present on the sealing material, and the cement-based material; z. Concrete.
• the filling or casting of a cement-based material is also referred to as installation.
• the substrate may also be a wooden substrate or consolidated gravel.
• the floor surfaces may be horizontal as well as at an angle 0 to the horizontal.
• this object is achieved by a method for the underfoot-proof production of water-sealed surfaces made of cement-based materials, in particular overhead surfaces, for.
• a sealing material on a substrate in particular a leveling layer, preferably made of shotcrete
• placing a reinforcement over the layer of the sealing material applying a bonding agent on the sealing material through the reinforcement through, installation, z.
• the formwork is a peripheral formwork (edge formwork) as a boundary of the ground or the floor area.
• the edge formwork can be done both before and after the installation of the reinforcement. In a normal construction process, but it is first built and then relocated the reinforcement. In this case, the seal usually goes under the formwork or is led up on the inside of the formwork.
• the sealing material is preferably applied in the form of sealing sheets, which are preferably laid overlapping and are glued or welded in the seam area, for example.
• the sealing material is based on FPO, TPE, ECB, PVC, EPDM, EVA, PE or the like.
• the adhesion promoter is expediently sprayed on.
• the adhesion promoter is a polymer-based dispersion, emulsion, suspension or solution based on acrylate, bitumen, cements or other substances.
• the surface of sealing material is cleaned of dirt, preferably by means of a liquid, in particular water, prior to the application of the adhesion promoter. If necessary, the excess or remaining liquid after cleaning can also be actively removed, for example by pumping.
• the present invention is based on the surprising finding that, due to the relatively late application of the adhesion promoter, it is in principle not damaged before installation of the concrete and thus retains its adhesion promoter effect. This, in turn, makes it possible to produce a good permanent surface bond with the hardening fresh concrete and to prevent the undercut of the surface seal in the event of unwanted damage.
• the "adhesive layer" in the form of the primer referred to above in the prior art is applied as late as possible, for example, by application of a special primer, or, in at least one particular embodiment, the specific primer with which (already laid) and later also with the fresh concrete, so that a bond between the sealant on the bonding material and the cement-based material takes place.
• FIG. 1 Stages of a method according to another particular embodiment of the present invention.
• Figure 1 shows, from top to bottom, a sequence of steps of a method of producing water-sealed wall surfaces from cement-based materials according to a particular embodiment of the present invention, wherein further steps may be taken between the steps shown.
• the erection of an outer formwork 10 takes place on a substrate (not shown in FIG. 1).
• a sealing material 12 is applied in the form of geomembranes over the entire surface on the inside 14 of the outer formwork. More specifically, in this example, the geomembranes are laid overlapping and welded in the seam area, for example.
• the sealing material may be, for example, FPO.
• a reinforcement 16 is arranged in front of the inner side 14 of the outer formwork 10 provided with the sealing material 12.
• an adhesion promoter dispersion 18, for example, is sprayed on the sealing material 12 through the reinforcement 16, for example on an acrylic basis. Normally, it can not be avoided that the reinforcement 16 is also at least partially coated with the adhesion promoter dispersion 18.
• Concrete 24 is then filled into the resultant formwork cavity 22 and allowed to harden to form a strong bond between the adhesive dispersion 18 and the concrete 24 on the sealant 12.
• the substrate 26 consists of a full surface applied cleanliness layer of unreinforced concrete.
• a sealing material 12 is arranged in the form of geomembranes, wherein the geomembranes are laid overlapping and glued in the seam area, for example.
• the sealing material 12 may be based on TPE, for example.
• a reinforcement 28 is arranged above the layer of the sealing material 12 and then a primer dispersion 18, for example, acrylate-based sprayed normally through the reinforcement 28, in which case the reinforcement 28 is at least partially coated with the adhesion promoter dispersion 18.
• concrete 24 is poured from above onto the reinforcement 28 and the concrete is allowed to harden to form a strong bond between the adhesive dispersion 18 and the concrete 24 present on the sealing material 12.
• a circumferential formwork (not shown) may be erected before or after the application of the reinforcement 28.
• overhead surfaces are to be sealed, this can be done, for example, by bonding geomembranes to the substrate (for example, ceiling or vaulted ceiling) and pegging a reinforcement with spacers.
