Natural Slates Certification                   

Cembrit's specialist knowledge and reputation for supplying the best natural slates makes collaboration with the superior Spanish quarries an obvious partnership. Probably the most forward thinking Spanish quarry self certifies its environmental credentials to EN 14001:2004. Furthermore the quarry has a reputation for being able to produce roofing slates to exacting high standards including a grade with minimal rust risk.
