Quality Guarantee–WIN-WIN Fair Stone
In accordance with the ethical principles of our natural stone business, we only export natural stone that has been extracted and processed under safe and legal conditions. The factories who produce the bus stop kerbstones for Switzerland have passed the audit with WiN = WiN Fair Stone–an international social and environmental standard for natural stone.
We ensure the ethical framework and support the life and work of the people in the stone processing plants and quarries by organizing training courses, handing over safety equipment and guaranteeing a certain amount of sales. With our commitment, we personally guarantee that we only sell ethically and ecologically harmless material.
