Quality management and certifications


Each subsidiary adopts an approach to continuous improvement of its products, services and production methods. We regularly measure the satisfaction of our customers. Our personnel is supervised and trained to achieve the quality targets set by Management.

Environmental control


Our activities are run so as to reduce their environmental impact, both by daily monitoring of environmental nuisance (noise, dust, blasting), and by rehabilitating the natural areas we exploit to best advantage. Substantial investment every year helps us improve our control of environmental nuisance.

Safety management


We constantly strive to modernize and automate our facilities in order to boost our production and make it safe (computer-controlled blasting, supervision of processes). We organize training programmes for our employees.
