QA Certificate
Certificate type
A unicoloured dark grey clay brick, with a sanded-coated and grained structure.
A mix of different kinds of clay forms the basis for this facing brick. Löss, the local loam of Aeolian origin dating from the Ice Age, is the base material. This löss mainly consists of a silt-like fraction, suited for the manufacturing of hand form bricks. By using specific sand types for surface covering, the desired colour is achieved.
