Travertine it is a porous limestone rock, made of calcite, weak magnesium calcite and aragonite, which has a yellowish to brown color. Being a porous material, when closing the pores with cement dust and after sanding and polishing, travertine becomes as fine as marble. This rock has an uneven structure, slightly hunted, which makes it especially suitable for cladding, both inside, as well as outside.

General technical characteristics:

  • Apparent density: 2,4 t/m3
  • Water absorption: 1 – 2,4 %
  • Compression strength: 0,17 g/cm2
  • Dry compressive strength: 33,5 N/mm2
  • Compressive strength after 25 of freeze-thaw cycles: 23,5 N/mm2
  • Mechanical shock resistance: 1,65 N/mm2


Travertine can be mounted on both screed and adhesive.


Travertine is most often used for interior cladding, having a rustic look, warm. Because of the porous constitution that gives it a certain fragility, travertine can also be used for exterior cladding but in mild climatic conditions.

Travertine comes in two structural varieties:

  • travertine compacte. They are dense and layered in thick banks (20-40 m) or in thin sheets, millimeter; they are white, cream-colored, Brown, which alternates throughout the crust. The stratification is assumed to be due to seasonal deposition, In the sense that in the summer the thicker and lighter bands were deposited, and in winter the thin, dark bands. These travertines are also known as cave onyx or marble onyx..
  • porous spongy travertines (also called “calcareous bushes”). These are white, and were formed by the biochemical deposition caused by the activity of aquatic organisms (especially blue algae), which retained carbon dioxide by photosynthesis (CO2) and caused carbonates to precipitate.

In general, travertine is porous. If the pores are closed with cement dust, by sanding and polishing, travertine takes on a surface as fine as marble.

The largest travertine quarry in our country is found in Banpotoc, Hunedoara county. The rock is yellowish-white and reddish-yellow. From the Banpotoc travertine, the sculptor Constantin Brâncuşi created two of his monumental works: The Table of Silence and the Kissing Gate.
