Santafiora Pietre srl was formed in 1964. One of the company's quarrying sites in Viterbo, Italy, has been in operation for 10 years. While the first five levels of this quarry produce Peperino Grigio, Lavagrigia is quarried from the sixth level and below.

Since 1964, Santafiora Pietre srl has been producing stone for both domestic and international markets. In particular, the company is well known for supplying high-quality durable stone for the building industry. With five quarries located in central Italy, as well as a processing plant, Santafiora Pietre is a strong entity among stone producers.

A second quarry on the company's property is six years old and produces Peperino Grigio.

The company is most noted for its production of Peperino - a volcanic stone that is speckled-gray in color. The name of the material actually refers to “salt and pepper.” Several varieties of the stone are available. They include Peperino Grigio Chiaro; Peperino Rosa, a less common and much valued material; and Lavagrigia and Lavarosa, an exclusive with the strongest technical qualities that is in great demand due to its darker shade, which is suggestive of the strength of the ancient volcanic rocks.

The company's stone-processing operation is complete with gangsaws to cut blocks into slabs.

In the Tuscany region, the use of Peperino dates back centuries. It has been employed for the building of important edifices, palaces, strongholds and city walls. It was during the Middle Ages that Peperino emerged in history and in architecture as an outstanding building stone - becoming the typical feature of the medieval “City of the Popes” and of the entire medieval quarter, according to Santafiora Pietre.

Machines at the plant run 24 hours a day year round.

Two of the company's five quarries are located at a site adjacent to the office and processing plant in Viterbo. One of the sites has been in operation for 10 years. The first five levels of this quarry produce Peperino Grigio, while Lavagrigia is quarried from the sixth level and below. The neighboring site is six years old and produces Peperino Grigio.

Among machinery at the fabricating facility is a Pedrini tile line.

According to Stefano Mutarelli of Santafiora Pietre, the company produces roughly 600 cubic meters of Peperino Grigio per month. Additionally, it produces 300 cubic meters each of Lavagrigia and Lavarosa.

Santafiora Pietre Srl specializes in the production of architectural elements such as curbs, outdoor fountains and paving.

Among the equipment at the plant are several gangsaws, Candiani wire saws, a Pedrini tile line, CGI slab polisher and a Commanduli Omega 100 edge polisher. Hand tools are also used for finishing work.

Peperino stone is ideal for outdoor applications because of its strength and durability.

The stone is available in blocks, raw slabs, semi-finished and finished products, including wall cladding, door and window surrounds, stair treads, coping, paving and sidewalk curbs. It is also offered in gauged and non-gauged flooring surfaces of different sizes, with a minimum thickness of 1 cm.
