Facing brick made entirely with red-baking diluvial clay from the Meuse valley. The clay is cast in one throw, which accounts for the characteristic irregularities and ribs of the finished brick. This red brick is fired at a very high temperature in a controlled atmosphere, and uses a controlled
atmosphere, and by using a unique and stable type of sand. This results in a virtually uniform red brick with virtually no colour differences. Slight colour variations from one batch to another are possible.
