GRACIOSA

The Tecnovia Açores industrial facilities on the island of Graciosa, at Rochela quarry, near the village of Praia, produce aggregates, ready-mix concrete, precast concrete and bituminous mixtures, which have been used in many contracts on the island.

Also at Rochela, Tecnovia Ambiente operates a Sorting and Recycling Centre for Construction and Demolition Waste – CDW.

The production centre has its own laboratory which performs production and quality control for the aggregates and bituminous mixtures which it produces, bearing CE marking in compliance with the applicable product standards.
