The Klaus Dieckerhoff GmbH & Co. KG renovated the sales areas of a REAL store in Bremen in 2016. The big challenge: a very large area of about 20,000 m² to be worked on. It was important here to create an optimal crack bridging and thus surface stabilisation. Tiles in 30 x 30 cm format were laid over the entire sales area. The primers, fillers, thin-bed and jointing mortars from codex were trusted.
