With our years of experience in industrial filtration, we devised an “all inclusive” maintenance concept which is being realized through the “De-dusting System Maintenance Outsourcing” model.

Globally recognized company CEMEX identified Wiena grupa as a perspective and qualified company; therefore, in 2012 it was awarded 1st place at CEMEX “Suppliers Innovation Programme” for this model. The commission in charge of selecting the most innovative supplier included 66 members from all over the world.

Also, we invest a lot of effort in safety at work. This resulted in the award for excellent results in the field of safety at work conferred by Cemex Hrvatska d.d., thus significantly singling out Wiena grupa from other cooperating members.


Wiena grupa implements and permanently maintains the integrated quality and environment protection management system, put in place in line with the requirements of international standards ISO 9001 and ISO 14001. Special attention is also paid to occupational safety. At the request of our long-term business partner Cemex Hrvatska d.d., the audit of occupational safety has been carried out by Bureau Veritas with a certificate of successful audit according to Cemex H & S requirements. The Wiena grupa’s score is 94%, thus classifying into the category Excellent.
