What is remarkably about Soreno? - haptic: an unusual, nearly soft appearance of the concrete surface is the result of the new developed manufacturing process. Concrete is not cold and rough anymore. Pleasantly barefoot accessible and still safe to walk on. - surface: filigree textured from very fine-grained natural stone grit, whose processing is not possible in the conventional production process. Process innovations. - esthetics: the smooth texture of the surface is discreetly emphasized by all shades of light. - cleaning: with the “CleanTop system” the slab is free from lime efflorescence and permanently protected against soiling.
