Two guarantees are better than one! Industrial production with ISO 9002 certification, concrete mixing plants with NF or DIN quality labels for ready-mixed concrete, attesting to the rigorous quality control and the internal and external controls carried out by the quality laboratory, in the mixing plants and on the sites. Solid trust is the basis of all good partnerships. The quality service manages the S.O.Q.E. (Safety, Organization, Quality, Environment) programme.
