The newspaper " La Nueva España " interviewed the engineer from Avilés, Cristóbal Lombardía after the execution of this emergency work, which bears the stamp of Perforaciones. Not all companies have the technical resources and qualified personnel for an emergency project where planning and execution time is an added value for the company. We would also like to mention Manuel Macías, the majority shareholder of Perforaciones, a mining engineer from Huelva who, together with his partner Cristóbal, are cautious and prudent regarding Perforacione's expansion on a national level. The extensive experience of both engineers has contributed to the company's solid growth plan. Perforaciones has participated in the Argayo APP66 slope reinforcement tender, the second phase of this project in Oviedo, where the company is located.
