CRISP Contemporary Concrete Tile. We usually imagine exposed concrete as being dull, grey and stark…beautiful qualities in their own right. But Crisp concrete tiles break the stereotype with a visual effect not usually associated with the material. Their glassy, reflective character is made possible with micro-refractions in waveform induced by small triangles that compose the surface. The result is a modern, delicate-looking finish with the same structural integrity as classic concrete.
