What people ask us about travertine.

A natural travertine quarry. We extract the stone at the face, cut it into blocks and saw it into slabs at our plant, in three shades: light, beige and dark.

The quarry is in La Laja, in the province of San Juan, Argentina. The plant is in the Parque Industrial Chimbas, also in San Juan.

At the quarry, a chain saw cutter and a diamond wire saw; in the stockyard, a gantry crane; and at the plant, a multi-wire saw and a bridge saw.

Rossara Stone is Cantera San Miguel's sintered stone brand. We sell travertine as Cantera San Miguel and sintered stone as Rossara Stone, with 320 × 160 cm slabs in Rosario and Buenos Aires.

It is a natural limestone that forms in layers from mineral-rich water. That is why it has veins and natural pores, which are left open or filled depending on the finish.

The background color and the vein. Each shade comes from a different bench of the quarry: light is ivory with a fine vein, beige is sand-colored with golden veins and dark is toasted brown with a chestnut vein. We also call beige intermediate (intermedio).

No. It is a natural stone and every block is unique: the shade is a guide. Before choosing, ask for a photo of the available block or a sample.

Dry, the sawn surface looks whitish from the cutting dust. Wet, it shows the color and vein it will have once polished.

Yes. Travertine is used on façades, patios and pool copings. For outdoor floors, a non-slip finish such as natural or honed is better than polished.

It depends on the use. Travertine is a natural stone: every slab is unique, with vein and pores, and it can be polished again over the years. Sintered stone is a manufactured material, even from end to end and in large, thin slabs, that resists stains and scratches well. We make both: travertine as Cantera San Miguel and sintered stone as Rossara Stone.

Yes. SEGEMAR (the Argentine Geological Mining Survey) measured, under the IRAM 12510 standard, a bulk density of 2.45 g/cm³, water absorption of 3.07 % and apparent porosity of 7.5 %. ITECA (UNSAM-CONICET) analyzed it by X-ray diffraction: it is 99 % calcite. We send the full reports on WhatsApp.

All three. The whole block; the slab sawn on our multi-wire saw, vein cut or cross cut; and cut-to-size pieces trimmed on the bridge saw: 20 × 60 cm, 80 × 80 cm, or 30 and 40 cm wide in free lengths.

They weigh between 10 and 12 tonnes. On average they are 2.40 to 2.60 m long, 1.00, 1.10 or 1.20 m deep and 1.00 to 1.40 m high.

It is the direction of the cut. In a vein cut, the cut goes across the layers and the slab shows parallel lines. In a cross cut, the cut runs parallel to the layers and the slab shows a cloudy pattern. The vein cut is more delicate, because the stone can split along the vein.

We usually sell travertine natural, straight from the cut and unfilled. On slabs we also do filled, polished and honed finishes.

For outdoor floors and pool copings, natural or honed, which are not slippery. For indoor floors, honed or filled, which have closed pores and are easy to clean. Polished brings out shine and color: it works best on walls, countertops and indoor cladding.

Message us on WhatsApp with the shade, whether you need blocks or slabs, and your city. We reply with photos of the available blocks or slabs.

With stone fabricators, distributors and importers, and architects and projects. We send each of them photos of what is available so they can choose.
