The properties of composite fillers made using both primary and secondary raw materials can be modified using different raw materials within the defined limits. There are fillers created specifically for the Dutch and Belgian markets. The fillers, which are of consistent quality, are produced and sold under the Vulprofite, Rhecom, and Vulcom brand names.
Cementbouw delivers a range of limestone fillers called Asphacal for the Dutch market.
Besides the standardised fillers, Cementbouw can deliver special products for specific uses in cooperation with its customers. Examples are products with properties like initial roughness and acid-resistance.
