sinkmar s.l.

In Sinkmar S. L. we have been offering our services to the general public since 1986. We are specialised in marble for cladding and we are located in the town of La Romana, in Alicante.

Luis Iñesta was responsible for creating the company dedicated to the manufacture of natural stone. Since then we have grown in human and technological capital to become what we are today, a benchmark in the country in the production of national and foreign marble.

We have a team of experts made up of workers from all areas of the company: production and processing, administration, logistics and sales. We ourselves manage the entire marble production process from the quarry to its final destination.
