VISEU

In operation under Tecnovia S.A. since 1986, the industrial centre of Viseu is located in Barbeita, near the village of Caçador, approximately 100 m from the IP5.

The Vale de Vaca quarry, where good quality grey granite is extracted, contains the raw material for the production of aggregates, ready-mix concrete, precast concrete, mortars and bituminous mixtures which have been used in several important construction projects throughout the region, over the course of the last 30 years.

The quality management systems at the Viseu centre are NP EN ISO 9001 certified, and products bear CE marking in compliance with harmonised product standards.
