The S.TONE Project

Lab.FW is one of the founding partners of S.TONE network, created with the main goal of representing all the entities that provide services to the natural stone sector. It is an independent structure that aims to ensure competitiveness and excellence of service, as well as the stability and growth of the sector.

Together with all key players in the natural stone sector, S.TONE promotes access to technical resources such as tests, assays, certifications and know-how, in order to achieve a greater international recognition and penetration.

Our vision

We believe that the physical-mechanical characterization of natural stone should not be seen just as the fulfilment of a legal requirement, but as an added value factor. Knowing, as well as possible, the properties of a product allows not only to know how to apply it better, but also contributes to a longer lifetime of the final solution.
