Hidden underneathWhere a river flows down the hill and crosses the landscape it reveals the cross section of the Earth's outer layers. These layers vary in colour and structure. The delicate and contrastive colours of our CONCEPT collection refer to these natural layers of sand, sandstone and loess. The unique graphic design and a polished surface make these tiles a material, which just like stone, is able to create interesting and glamorous arrangements. The collection is perfect for utilization in large areas, where it will fully exhibit its extraordinary decorative values.
