Correct and final sealing of the floor and cold room area
The screed surfaces and the cold room base must then be completely covered with the sealing material, ideally reaction resin. Only then can insulation strips be inserted between the floor and the cold room in order to compensate for differences in load. The open area is then filled up again, ideally with a high-quality building material that does not absorb moisture even over a long period.
In order to securely seal the connection between the cold room and the floor, we recommend the use of a filler cord. This filler cord prevents cracks from forming in the seal later due to the expansion joint. Finally, the expansion joint is sealed with high-quality silicone and must be checked at regular intervals and replaced if necessary.
Special focus on the door area and on skirting tiles
The floor structure in front of the cold room must be absolutely level, otherwise, water may flow towards the cold room over time and provoke the accumulation of liquids. During the tiling process, the last 1-2 rows of tiles in front of the entrance may be installed at a slight angle to help fluids flow away from the cold room.
If skirting tiles are supposed to be attached to the cold room itself, Viessmann recommends using wall elements with a tile adapter. Tile adapter means, that the TectoCell walls are tapered at the relevant points so that a level connection of the base tiles is possible. For this purpose, the lowest part of the cold room wall is narrower than the upper part.
