Slate is a 100% natural product that is only submitted to extraction and shaping processes. It requires no additional treatment, make it the sustainable alternative for any project.

All the natural slates that bear our brand have been produced directly in our factory and, therefore, are subject to our quality and environmental management policies.


The exploitation process commences once the geological, mineral and geotechnical surveys have been concluded, in addition to the prospection work and sample testing to determine the quality of the slate and the potential reserves of the deposit.
Regular surveys and trials are conducted throughout the life of the exploitation with the aim of preparing the quarry for the future and to guarantee a continuous and steady production of high-quality slate.



Extraction of the product commences after conducting the disassembly operations.
The slate is extracted in large blocks cut with a diamond blade. The blocks are then transported by truck to the quarry processing plant. Water is used as a coolant and base material for removing rubble throughout the process involving the extraction and processing of the product. This water is recycled and purified in a closed circuit to prevent such a precious resource from being wasted.


The slate undergoes 3 or 4 phases at the processing plant depending on the final product, prior to being packaged:
– Sawing: The large blocks of slate extracted from the quarry are sawn into different sizes in accordance with the size of the slate to be produced.

- Splitting: The slate is then hand split at desired thickness. The water ensures the blocks do not dry, facilitating exfoliation and reducing loss.

- Calibrating: The riven slates are then calibrated to exact thickness required.

– Shaping:Then, workers cut each piece into desired dimention, treating each item with meticulous care, all of which is done by hand.

After classification the slates are counted and packaged on wooden pallets for storage and subsequent delivery.
A label is placed on each pallet with a description of the slate (quarry and plant of origin, format, thickness, etc.); in addition to the name of the person in charge of selection.
