DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0073] In the following figures, identical or similar elements may be labelled with the same or similar reference numbers. In addition, the figures of the drawing, their description and the claims contain numerous features in combination. It is clear to a person skilled in the art that these features can also be viewed individually or that they can be selected to form other combinations not described here in any more detail.

[0074] Shown in FIG. 1 is a rectangular, large-format panel module 10, comprising a building panel 30 and a wearing layer 31 made of natural stone tiles 32. As an alternative to a wearing layer 31 of natural stone tiles 32, ceramic tiling may be provided, thus resulting in a panel module 10. In the exemplary embodiment shown in the figures, panel modules 10 are installed on the floor and panel modules 10 are installed on the walls.

[0075] In the case of both panel modules 10, 10, the wearing layer 31 is connected to the building panel 30 by means of a bonding layer 12. The panel module 10 has an outer contour 20 which corresponds to the marking on the floor 14 (cf. projection in FIG. 3). A marking of the corner points of the outer contour 20 is sufficient for the subsequent application of the sealing strip sections 16, 17.

[0076] As an option, the panel modules 10, 10, in particular the wearing layer 31, can be covered with a removable protective foil 29.

[0077] The sandwich-like building panel 30 comprises a watertight core 11 made of extruded polystyrene rigid foam that is coated on both sides with a fiber-reinforced, hardened cover layer 13 of synthetic mortar.

[0078] The bonding layer 12 is made of watertight, thin-bed mortar based on hydraulic binding agents. With its cementitious surface, the thin-bed mortar forms a good bonding base. In the present case, for example, Wedi 320 tile cement is employed, a product of the company wedi GmbH, Emsdetten, Germany.

[0079] The panel modules 10, 10 preferably have the format 2500 millimeters by 600 millimeters. Naturally, other format sizes can also be employed. The panel module 10 shown in FIGS. 1 and 2 is provided for installation on the floor 14 (cf. FIG. 3) and, depending on the thickness of the cover layer 13, has an overall thickness of 40 to 50 mm. Initially, that is to say prior to renovation, the floor 14 has an existing old floor covering.

[0080] In FIG. 6, existing, tiled and partially damaged walls 15 and the floor 14 in a corner region of a wet room 100 can be seen. The leaks and damages in the old tiling are indicated with reference number 33. In order to repair the wet room in this situation, renovation measures must be taken.

[0081] After the installation position of each panel module 10, 10 has been determined by marking, for example colored marking, sealing strip sections 16, 17 are adhesively laid, as shown in FIGS. 3 to 6. According to FIGS. 3, 5 and 6, the sealing strip sections 16 are first laid in a manner similar to known plastic skirting boards. Thus, the sealing strip section 16 is first glued on the floor 14 and on the adjacent wall 15 across a transition area 18 of the floor 14 to the wall 15 so that it lies with one half on the floor 14 and the other half on the wall 15 in an L-shape. The sealing strip section 17 running along a corner 35 of the walls 15 arranged perpendicular to one another is also laid in an L-shape.

[0082] It can be seen from FIG. 4 that the upper half of the sealing strip section 16 is glued to the wall 15 by means of an additional adhesive after the panel module 10 has been laid and pressed upon the half of the sealing strip section 16 on the floor and on the floor 14 itself. The additional adhesive is applied by a manually guided tube 27. As an alternative, an adhesive strip provided with a protective foil can first be applied to the rear side of the sealing strip section 16. The bond is made by peeling off the protective foil and pressing the sealing strip section 16 into place.

[0083] Once the sealing strip section 16 has been bonded seamlessly to the wall 15, further sealing strip sections 17 are affixed to the floor 14 and to the wall 15 perpendicular and parallel to the laid L-shaped sealing strip section 16. In FIGS. 6 and 7, overlaps 36 of vertically glued sealing strip sections 17 on the applied L-shaped sealing strip sections 16 can be seen. The attached sealing strip sections 16, 17 form rectangular borders 34 (cf. FIG. 6) into which the provided panel modules 10, 10 are inserted.

[0084] Both kinds of sealing strip sections 16, 17 are preferably cut to length from a solvent-free butyl adhesive tape with good flexible properties and extreme adhesive strength.

[0085] FIG. 5 shows a similar exemplary embodiment to FIG. 4. In contrast to the exemplary embodiment of FIG. 4, the original floor comprises a floating screed 38 which is decoupled from the wall 15 and the slab 40 by a separation layer 39. In order to maintain the decoupling of screed 38 and wall 15, an additional decoupling strip 41 is provided between the panel module 10 and the wall 15, which in the shown exemplary embodiment is a tub sealing tape with a self-adhesive decoupling strip offered by the manufacturer wed i.

[0086] Before the panel module 10, 10 is inserted, adhesive beads 22, 22 having a diameter of approximately 10 mm are applied continuously to the border 34 along its circumference. As an alternative to two parallel adhesive beads 22, 22, a single adhesive bead can be provided which is wide enough to underlay the edge region of two adjacent panel modules 10, 10 when fully assembled.

[0087] In the installation plan of the panel module 10 shown in FIGS. 3 to 5, the sealing strip section 16 projects beyond the upper edge of the panel module 10. This part of the sealing strip section 16 projecting above the panel module 10 will subsequently be covered by a wearing layer 31 to be applied to the wall 15 or by a panel module 10, thus sealing the transitional area. If the existing wall 15 is not to be faced with a wearing layer 31 or panel modules 10, it is also possible to install or truncate the sealing strip section 16 such that the upper edge of the sealing strip section 16 ends with upper edge of the panel module 10 installed on the floor. This exemplary embodiment (not shown in the figures) is particularly well-suited in cases where only the floor of the room is to be renovated as part of wet room restoration. This exemplary embodiment is in particular also well-suited when the panel module is a shower floor panel used for installing a floor-level shower in a sanitary room.

[0088] As shown in FIGS. 6 and 9, two adhesive beads 22, 22 are applied to each sealing strip section 16, 17 at a distance 21 from one another. The double row of adhesive beads 22, 22 ensures the required tightness. Preferably at least one further adhesive bead 22 (cf. FIG. 6) is also applied between sealing strip sections 16, 17 lying opposite one another, in other words within each border 34. The use of bulging adhesive beads 22, 22, 22 also contributes to improved acoustic insulation.

[0089] The panel modules 10, 10 are inserted by being pressed onto the borders 34 covered in this way with adhesive beads, resulting in overlap areas 19 of two adjoining panel modules 10, 10 which form a joint 24. Such overlap areas 19 are found at all panel module transitions. After all panel modules 10, 10 have been attached to walls 15 and floor 14, the joints 24 between the panel modules 10, 10 are filled with a joint grout and sealed in the conventional manner. Since the adhesive beads 22, 22 run in an uninterrupted manner, seal points 23 (cf. FIGS. 2 and 10) are produced between the panel modules 10; 10 which prevent the further passage of water from entering behind the panel modules 10, 10 through leaky joints 24, even when the joints 24 between the panel modules 10, 10 are badly sealed or lose their tightness through decomposition.

[0090] The necessary pipe openings can also be well sealed in the same manner with adhesive beads 22 before the insertion of the panel module 10. FIG. 9 shows a wall section having an aperture 25 for a pipe opening 26. A sealing collar 28 is applied around the pipe opening. Before and after the installation of the sealing collar 28 a sufficient quantity of adhesive and sealant is applied to the existing wall 15 around the pipe opening 26 without interruption of the adhesive web and carefully leveled off. Additional adhesive beads 22 are also applied to the area surrounding the pipe opening 26. Only afterwards is a panel module 10 installed which has a previously cut opening (not shown) which conforms to the position of the pipe opening 26.

[0091] For all adhesive beads 22, 22, 22 a flexible, water-resistant adhesive sealant wedi 610 was employed, a product of the company wedi GmbH, Emsdetten, Germany.

[0092] The panel modules 10, 10 can be pressed on the adhesive beads manually or mechanically, for example with vacuum support.

[0093] FIG. 11 shows a renovation kit 50, essentially comprising a coordinated number of panel modules 10, 10, sealing tape rolls 37 from which the sealing strip sections 16, 17 can be cut to size, and tube 27 with nozzle and containing the adhesive sealant wedi 610.

[0094] The panel modules 10, 10 illustrated in the figures are building panels 30 provided with a wearing layer 31. As an alternative, or in combination with such panel modules, the method according to the invention can also be carried out with all other types of panel modules, such as natural stone slabs, building panels not provided with a wearing layer 31, glass panels, etc., inasmuch as these panel modules are watertight or at least have a watertight core.
