Those with a flair for things extraordinary and opulent will be enchanted with the new prefabricated components from the Lang “Passion for Concrete” Premium Line. “Crystal Concrete” can take even dyed-in-the-wool concrete connoisseurs by surprise. This new product is a combination of self-compacting concrete and Swarovski crystals in a panel form. Its special feature is that the crystals are flush mounted in the concrete during its manufacture.
