Urban Grey Porphyry, quarried in the Rio de Janeiro region of Brazil, is a remarkable dark grey porphyritic gneiss. This versatile stone offers a wide range of applications, including paving, setts, curbs, cladding, slabs and more. Its exceptional hardness and outstanding technical properties ensure durability, while its consistently beautiful color and uniquely textured natural surface truly set it apart.

One of the key advantages of Urban Grey Porphyry is its naturally slip-resistant texture, resulting from its inherent ability to be split along its layers. Unlike many other stones that require additional treatments like flaming for slip resistance, Urban Grey Porphyry excels in sustainability as it doesn't need such processes.

Notably, Urban Grey Porphyry bears a striking resemblance to Luserna Gneiss, a renowned Italian stone quarried in the Alps.
