Filstone

Combining the constant search for excellence with the development of innovative processes is the premise that has guided Filstone’s performance. 

With a focus on respect for the environment, the company benefits from the exceptional characteristics of Serra de Aire and Candeeiros, which guarantees some of the most renowned limestones in the world. 

Its positioning in the sector is due to the quality of its products, to the demanding deadlines and to a competitive strategy based on the proximity to its customers and suppliers. 

The certification of its products with the StonePT brand favors the consolidation of the brand in the international markets and reinforces the guarantee on the origin of natural stone, which presents a reliable solution, worthy, attractive and one of the most nobles on the market. 

In these 19 years, Filstone continues to support its intervention in an altruistic stance, with a strong commitment to act for the surrounding communities and the environmental sustainability. It is now an example not only in Portugal but also across borders, and a key partner in supporting various public causes.
