The true protagonist is the Ulldecona or Cenia stone.
This is an extraordinarily hard and aesthetically attractive limestone that, due to its technical characteristics, admits many types of finishes, from polished and glossed to semi-rustic and rustic. Due to its degree of crystallization, it is part of the marble family.
Widely used in construction and decoration, both for exteriors and interiors, the Cenia stone offers endless possibilities that customers around the world already appreciate. From our quarry, considered one of the most productive and of the highest quality in terms of Cenia stone, we obtain an optimal material that we make available to you to satisfy each and every one of your needs.
We look forward to welcoming you. Come to Marbres Homedes and discover everything that the extraordinary quality of our Cenia stone can offer you.
