Travertine is the most porous natural stones. Its high porosity is the reason why a large number of homeowners do not choose it for their project.

However, despite being highly porous, travertine stands as an extremely beautiful and strong stone. If you are choosing the right surface finish, you can use it for outdoors as well. While other natural stones become slippery and prone to accidents, travertine doesn’t because of these tiny pores.

But what is it that makes travertine highly porous. In the following, we explain some of the reasons behind travertine’s high porosity –

What is Porosity?

 Put simply, porosity of a stone is the ratio of pores to its complete solid volume. If the porosity level is high, the stone is highly porous and absorbent. The higher the porosity or absorbency the more it is likely to catch stains.

How Do Stones Get Pores?

Stones get pores during their formation process. So, understand that, we will need to get an understanding of how stones are formed.

As we all know that stones are processed from rocks formed over a long period of time under heavy pressure and temperature in the earth’s crust. And when they cool down, they develop cracks and pores - which are the natural properties of the rock/stone.

The pores appear during the crystallization and re-crystallization process of the rock.

However, pores can be filled with sealant. With travertine, you have the option to buy unfilled and filled stone for your specific purpose.
