The Böhringer Ingelheim company has its headquarters in the heart of Rheinhessen. In order to offer the steadily growing workforce the opportunity to spend their lunch break with healthy food and in a pleasant atmosphere, a new employee restaurant was recently opened on the company grounds of the headquarters. The restaurant covers an area of around 1,900 m² and can accommodate around 3,500 employees. The canteen kitchen alone comprised 1,930 m² of floor and wall areas that had to be laid.
Highly resilient canteen kitchen area
When laying the tiles in the two critical areas, challenges had to be mastered. The best care and greatest attention cannot prevent that substances such as water, acids, fats and oils spread in a commercial kitchen. If there are cracks or damages in the covering, these penetrate into the subfloor and the screed gradually begins to decompose. In the worst case, this could also affect the underlying supporting structure. Complete waterproofing is therefore essential, and that is why codex Hydrostop (waterproofing membrane), codex Power RX 6 Turbo and codex Epo 2000 were used in wet areas. The tiling and tile grouting afterwards was carried out with the flexible thin-bed mortar codex Power CX 3 and the special jointing mortar codex Resist. The particularly chemical-resistant epoxy resin joint codex Epo Tix was used in the chemically and mechanically highly stressed scullery.
Large room with uniform overall impression
In the restaurant area, the challenge was to create a smooth, monolithic-looking overall surface with 80 x 80 cm large format tiles. The substrate consisted of a cement screed with underfloor heating and already had existing movement and field boundary joints on site. Thus, the special task of the joint pattern was also to create a harmonious overall impression over the extremely large area despite the existing movement joints. The appearance of the floor covering should be uniform at the end and without disturbing influences. In order to guarantee safety and a functional floor covering, it was decided to lay an uncoupling strip under the tiles to compensate tension between the substrate and the covering. A safe and durable installation of the large format tiles was last guaranteed by the Power RX 8, which is very easy to work with and adheres excellently to the substrate and the tiles.
