SÃO JORGE

Tecnovia Azores operates three quarries on the island of São Jorge, from which it obtains stone to produce aggregates, riprap and TOT.

At the industrial facility in Queimada, on São Jorge, Tecnovia Azores extracts basalt from the Queimada quarry to produce aggregates, and also produces ready-mix concrete, bituminous mixtures and precast concrete for maritime contracts. This industrial facility also has a centre for collecting, recycling and sorting construction and demolition waste – CDW, which is operated by Tecnovia Ambiente.

Tecnovia Azores also exploits two other basalt quarries in São Jorge, the Pico da Calheta quarry and the Urzelina quarry, to obtain large riprap and TOT, which are mainly used for maritime projects.

Production and quality control is performed by the Tecnovia Azores laboratory in compliance with applicable testing standards.

Quality management systems are NP EN ISO 9001 certified. Aggregates and bituminous mixtures bear CE marking in accordance with product standards.
