2. The method according to claim 1, wherein the groove (8) surrounds the opening (9) of the drainage body (2).

3. The method according to claim 2, wherein the groove (8) is at least partially spaced apart from the opening (9) of the drainage body (2) such that a gap (10) exists between the opening (9) of the drainage body (2) and the groove (8).

4. The method according to claim 3, wherein the gap (10) encircles the opening (9) of the drainage body (2).

5. The method according to claim 3, further comprising the step of arranging an odor trap (11) and a removable frame (12) for the odor trap (11) in the gap (10) between the groove (8) and the opening (9).

DETAILED DESCRIPTION OF THE INVENTION

(11) FIG. 23 and FIG. 24 show a sealing device 1 according to the invention before attachment to a drainage body 2 of a drainage arrangement according to the invention. The sealing device 1 has a waterproof sealing film 3, which can be composed of different types of plastics. The sealing film 3 has an, in particular rectangular, opening 4 (see FIG. 24), through which water can flow to the drainage body 2.

(12) A support 5, which has on its side facing the opening 4 a circumferential seal 6, in particular a lip seal, is attached at the bottom side of the sealing film 3. The support 5 may be constructed of a hard plastic such as PP. The seal 6 may be constructed of a soft plastic such as TPE.

(13) The drainage body 2 is constructed as drainage housing with a housing cover 7 which also has an, in particular rectangular (see FIG. 24), opening 9. The support 5 with the seal 6 can be inserted, preferably snapped or clipped, into a circumferential groove 8 of housing cover. A gap 10, which can be used, for example, to displace a portion of the water collecting device (see, for example, the substructure frame in FIG. 3 and FIG. 4) disposed on top of the drainage housing, remains between the groove 8 and the opening 9.

(14) FIGS. 19 and 20 depict the present inventive sealing device 1 after attachment to the drainage body 2 of a drainage arrangement according to the invention. Similarly, FIGS. 21 and 22 show the same embodiment depicted in FIGS. 19 and 20, respectively, with the addition of an odor trap 11 and a shuttle frame 12 for the odor trap 11 arranged in the gap 10 between the groove 8 and the opening 9.

(15) When the drainage arrangement is installed, a composite seal is applied on the sealing film 3, onto which in turn tiles can be placed.

(16) The sealing device in accordance with the present invention may be incorporated into a drainage channel as the water collection device, for example as illustrated in FIGS. 1 to 10. With this approach, a lateral compensation of the substructure frame within the sealing device 1 or in the gap 10 is possible perpendicular and parallel to the wall.

(17) The sealing device in accordance with the present invention may also be incorporated into a drainage profile as the water collection device, for example as illustrated in FIGS. 11 to 18. With this approach, a lateral compensation of the profile is possible on and within the sealing device and the composite seal arranged above, or in the gap 10 perpendicular and parallel to the wall.
