The origin of the Santullán Quarry dates back to the 60s when the owners of the company, currently the fourth generation of a family owned and independent business group, decided to start a new exploitation of high purity calcium carbonate minerals in the Santullan municipality in order to meet the demand for this mineral of the heavy industry in the peripheral area of Bilbao (Bizkaia).

The priority criteria for choosing this location for the exploitation were the very high purity of calcium carbonate, the virtually inexhaustible reserves and the proximity to the market, which were initially mainly the steel, chemical and lime manufacturing industries of the region.

Our extensive experience in supplying mineral calcium carbonate and aggregates for industrial uses, construction projects and civil works is totally focused on meeting the needs of customers, no matter how demanding they are.

As a result we can look back on 60 years of track record in which we have always met the deadlines and the volumes we agreed upon contractually with our customers. Without exception.

The guarantee for reliability and quality, without one single claim of our customers throughout the history of our company.

  • QUALITY 100%
  • GUARANTEE 100%
  • QUICKNESS 100%


To a large extent this has been possible thanks to a stable, experienced and highly qualified staff. One of the cornerstones of our family business is to provide stable and quality employment, building a professional team, defending on all levels the company values, with hard work and honesty offer our customers an excellent product and service.

Therefore Santullan prioritizes on direct recruitment of its employees, with virtually no outsourcing.

In addition to a staff formed almost exclusively by local people, Santullan promotes the hiring of young workers, providing them with a solid training and taking advantage of the mining experience of our veterans, some of whom have been with the company for more than 47 years.

At management level, the exploitation of the mine, including production, logistics as well as the technical and commercial support, is conducted by a team of highly experienced engineers with a proven track record in the sector and totally focused upon satisfying the needs of our customers.
