The KEMPEROL success story began in 1969 when the VW Building Department asked Dr Heinz Kemper to find a solution for the apparently insoluble problem of leaking flat roofs. This innovative entrepreneur, the owner of Kemper Kunststoff & Lackfabrik just a few miles down the road at Vellmar/Germany, had already completed various contracts for VW. He accepted the challenge immediately because he recognised the enormous economic potential. He couldn’t have chosen a better time!
Expansion joints, details and junctions proved to be especially vulnerable to problems. Structural movements and the diverse behaviour of different materials very quickly led to cracks in the waterproofing. Moisture began to penetrate and threaten the hitherto untroubled manufacturing operations. Dr Kemper had already used polyester for internal waterproofing measures. He now started testing ways to make polyester flexible. He was looking for a permanently elastic material that could accommodate stresses in the substrate and compensate for structural movements without tearing, without becoming brittle.
After many disappointments, the 210th test finally proved successful. And that first liquid waterproofing material has retained its unspectacular, technical designation to this day: KEMPEROL V 210 (V = Versuch = test). The threecomponent liquid waterproofing system based on unsaturated polyester resins began its success story, which has continued for the past 35 years.
Over the past 35 years more than 300,000 m² of roof surface has been waterproofed with KEMPEROL. The liquid waterproofing material is ideal for critical areas, for example, where ponding occurs owing to inadequate falls. The positive experience with KEMPEROL V 210 lead to some major applications in the automotive industrie: e. g. to the waterproofing of 60 000 m² on the roofs of BMW Steyr, Austria.
