Who we are – Our History
We are a company with over 40 years of experience, located in Castejón (Navarra), Spain. Our main activity is the crushing and grading of aggregates, concrete manufacturing, commercialization of technology and service like concrete pumping, cranes, containers, earthmoving and building demolition.
The company has been growing and it has adapted and invested to meet the increasing needs of its customers, in terms of quality, technology and continuous improvement. It was this desire for continuous improvement which made us get the ISO 9001:94 certificate in December 2001 and then adapt easily to the new ISO 9001:2000 in September 2003.
In 2002, a project, which started in 1997, was completed and led to a new subsidiary company called CANTERAS EL CERRO S. L. This new company operates a black limestone aggregate quarry in Igea, La Rioja, Spain.
Our Black stone extracted from our quarry has an intense colour, unique in Spain, with extraordinary qualities as a building material, cements, precast and asphalt, as well as for the manufacture of terrazzo, due to its high strength.
