Kemperol BR / BRM, a fleece-reinforced polyester resin-based waterproofing system, was specially developed for use under extreme conditions. For a quarter of a century, this tried and tested system has been reliably protecting reinforced steel and concrete structures against damage from water and corrosion.
Kemperol BR / BRM is ideally suited for vegetated roof and IRMA roofing assemblies, it can be laid under asphalt, slabs or paving. Poured asphalt can be laid at 480 °F without damaging the membrane. Permanently-elastic Kemperol BR / BRM bridges cracks up to 2mm making it an ideal waterproofing solution for sufaces with vehicular or pedestrian traffic.
