Baumeister: What gap in the Dallmer portfolio does the new “CeraFrame Liquid” shower channel fill?
Ralph Wagner: Barrier-free shower drainage is Dallmer’s domain. As a rule, shower floor coverings are made of porcelain stoneware, i.e. tiles, or natural stone in the particularly sophisticated segment. In recent years, we have observed a trend towards ever larger formats. The intention behind this trend is to have as few floor joints as possible. This is because the joint is always a potential weak point: on the one hand, it lets moisture through, which is why the bonded waterproofing underneath the tile layer is necessary in the shower. Secondly, joints are more susceptible to dirt and more difficult to clean than the floor covering. In particularly minimalist bathroom solutions, people now go one step further and create floor coverings without any joints at all. Trowel materials, i.e. thin-layer design floors, are generally used for this. They are usually only 3 to 4 millimetres thick and are applied by specialist companies in several layers and by hand. Dallmer has developed “CeraFrame Liquid” for these floors.
B: Why can’t drainage systems for tiled or natural stone floors be used for these thin-layer floors?
RW: Dallmer shower drainage systems for use with porcelain stoneware or natural stone are designed in such a way that water penetrating through the joints can drain away via a secondary drainage system in the drain. This secondary drainage is not present in the “CeraFrame Liquid” because no water can penetrate through joints. With thin-layer floors, on the other hand, it is very important that the transition between the floor and the drain is absolutely watertight so that no water can get under the coating. We have responded to this challenge with a solid channel milled from a single piece of stainless steel, which has a completely closed channel contour. This channel is inserted into the drain body by means of a seal. The two components meet inside the sealing sleeve. There is also a sealing ring for additional protection. The two components are also screwed together.
B: Is there a difference in function to the “CeraFrame” for tiled surfaces?
RW: The drainage performance is absolutely comparable because the drain bodies are the same as in the models for porcelain stoneware and natural stone. The cover for cleaning the system also has the same dimensions. The only difference is that with “CeraFrame” for tiling, the cover is either made of visible stainless steel or a piece of tile or stone is fitted. With “CeraFrame Liquid”, the stainless steel cover has a fine upstand on the top. This allows the surface on the cover to be filled with the thin-layer covering. Only a fine stainless steel edge remains visible. Cleaning itself is carried out in exactly the same way as with the “CeraFrame”: the trap can be removed and cleaned in one easy step. It can now even be taken apart and can therefore be cleaned precisely down to the last corner.
B: For which areas of application is “CeraFrame Liquid” particularly interesting?
RW : We anticipate that “CeraFrame Liquid” will be particularly in demand for the living area, i.e. for private houses and apartments. This is because the thin-layer floor coverings can be used to create highly individual and unusual bathroom designs. In terms of color, for example, there are hardly any limits with these floors. Nevertheless, I could very well imagine that the system will also be used in the hospitality sector in the future. Hotel bathrooms are often an important source of ideas for the entire bathroom area. Especially where space is limited, seamless floors convey a sense of spaciousness. PU-based thin-layer floors, which are particularly attractive in terms of price, are very well suited to the hospital and care sector, for example.
B: Does the installation of “CeraFrame Liquid” represent a major change for the installation company compared to “CeraFrame” for tiles and natural stone?
RW: In practice, the installation company doesn’t have to change at all, because with “CeraFrame Liquid” only the top is designed differently. The drain body underneath is also the tried and tested “DallFlex” system. This is a huge advantage for the installer.
B: How does the cooperation between the installer and the floor layer work on the construction site?
RW: Normally, the specialist company that applies the thin-layer floor covering will also lay the screed in the shower as a preliminary trade. The screed is already slightly modeled so that the shower surface has a slight slope to the drain. Sloping cuts, which would be necessary with a porcelain stoneware or natural stone floor, are unnecessary here. This gives the floor covering a very uniform and harmonious appearance.
B: Can I use any thin-layer floor covering for floor-level showers?
RW: The thin-layer wall and floor covering must be suitable and tested for the wet/shower area. The connection of the wear layer to the shower channel must be checked and the manufacturer’s instructions must be observed.
B: Will Dallmer also offer solutions for seamless floor coverings such as terrazzo in the future?
RW: Terrazzo is a floor covering that appeals enormously to architects and is very popular with them. However, it cannot be applied as a thin-layer covering due to the natural stone particles it contains. Terrazzo requires installation thicknesses of at least 15 millimeters. At the moment, the covering thickness of “CeraFrame Liquid” is limited to 4 millimetres. However, if there is demand for a product for covering thicknesses above 4 millimetres, this could be implemented quickly.
