Functional fibres for concretes & mortar

Industrial Floorings, Precast Concrete Elements …



Since the 1980‘s the PB EUROFIBER brand has made a name for itself as a performance additive to improve construction materials. Our functional fibres are used to optimise product and processing properties in a wide variety of technical products including concretes, cement-based mortars, adhesives and dry-mix compounds.

PB EUROFIBER has been successfully used to enhance the fire resistance of concretes and cement mortars since the 1990‘s.
