Geological Recognition

Long before the modern industrial structure, the scientific value of our slate had already attracted the interest of distinguished geologists, mapping what would become a global legacy in the Valongo Formation.

Traditional transportation
Tradition: Ox carts used to transport slate in Canelas.
Memory

Transportation from the Origins

Animal strength and human skill came together to conquer the slopes of Arouca, transporting the raw material that would shape the traditional roofs and soul of our region.

The Wisdom of Hands

In an era of rudimentary tools, it was the hearing and touch of the louseiros (woodcutters) that dictated the perfect splitting plan, a manual technique that we still preserve today as a mark of quality.

The Dawn of a New Era

Through the revitalization of local knowledge and a specialized course for louseiros, we have restored the parish of Canelas' economic engine and its greatest source of industrial pride.

Building the Structure

The construction of the administrative headquarters in 1988 symbolized the solidity of the project. We were no longer just a quarry, but had become an organization focused on excellence and the global market.

Artisanal extraction
Production: The rigor of artisanal extraction in the first months of operation.
Technique

Respect for the Material

Handcrafted extraction allowed us to gain a deep understanding of the rock. Each block was treated with the reverence that a 465-million-year-old material demands, ensuring the integrity of the cleavage.
