Categories: Services Products Situation Contact Canteras Fernández Pascual is a company dedicated to the extraction and treatment of limestone. It has its exploitation center in the Rioja town of Leza de Rio Leza , 19 kilometers from Logroño on the LR-250 road. The “La Carolina” quarry has estimated reserves of more than 9 million cubic meters of calcite-type limestone. It was opened by Jesús Fernández González in 1968 , whose family has been linked to the world of aggregates for more than 100 years. In the treatment plant at the same quarry occur sands , gravels and graded aggregates of different particle sizes and stone rubble for the construction of retaining walls. All our aggregates have their corresponding CE marking depending on the use to which they are intended. The limestone rock that is extracted from our quarry has a calcium carbonate purity of 99%. We have recently started up a plant for the production of micronized calcium carbonate for agricultural, livestock and industrial uses, which we serve in bulk, in pneumatic tanks, or packed in sacks or bigbags. Our production process is totally respectful with the environment, being in possession of the quality seals 9001 and 14001 .
