Origin & quarry

Pietra Piasentina is worked in the hills of eastern Friuli, near the Slovenian border. It is specified precisely where a calm grey stone has to survive weather, salt and abrasion: a dense, hard stone that has become a regional standard for exterior paving, stairs and ventilated facades in demanding Alpine climates.

Geology. Dense calcareous stone (a hard limestone/breccia) with grey to grey-brown ground and fine calcite veining; low water absorption is what makes it stand up outdoors where softer greys fail.

Where it works

Specify with confidence

  • Exterior paving, stairs and thresholds
  • Ventilated facades and rainscreen panels
  • Hardscape in freeze-thaw climates
  • Heavy-traffic interior floors (brushed/honed)

Use with care

  • Mirror polish: better read honed, brushed or flamed
  • Projects wanting a bright-white look (this is a grey)
  • Confirm slip rating with finish for wet exterior

Good to know

Why choose Pietra Piasentina for exteriors?

It is dense with low water absorption, so it resists weathering, salts and abrasion far better than porous decorative greys; a sound exterior-grade choice.

Where is Pietra Piasentina used?

A tough Friulian limestone widely specified for interior and exterior floors, stairs and cladding, valued for its durability and calm grey-beige tone.
