Bitumen Systems

Our range of Reinforced Bitumen Membranes (RBM) combine strength with longevity to provide a durable waterproofing solution. Suitable for all roof applications, with a variety of options to meet all build and cost requirements, our broad range of RBM systems include Excel, Force, Hyranger, Force Dalle and Cityflor, as well as our commercial RBM Force Line systems. We have a long tradition of manufacturing bitumen membranes, and our portfolio has been carefully honed by our expertise to ensure every system performs to the highest standards in order to meet the ever-growing demand for increased life cycle.


An ancient material continually evolving to provide versatile and robust waterproofing. RBM systems have seen a significant increase in popularity due to the commercial demand for a highly durable and sustainable roofing option. A natural derivative of petroleum, bitumen is extracted by a simple distillation process that generates very little CO2 and has minimum impact on energy resources. Reinforced bitumen membranes can accommodate extreme stresses from thermal movement and wind load, whilst withstanding a higher degree of construction and maintenance traffic, making it an ideal choice for new build and refurbishment projects.
