Elastomer bitumen sheet with synthetic fleece in a thickness of 4 mm.
Elastomer bitumen is highly elastic ("rubbery") and thereby remains flexible even at low temperatures.
The synthetic fleece reinforcement is particularly durable, has excellent tensile strength and is resistant to static and dynamic stresses.
The surface texture upside and the downside has fine granule.
The bonding is done by torching, pouring or slip-casting method.
The bitumen is heated in a suitable bitumen boiler and in order to submerge the waterproofing sheet a metal watering can is used.
Dörrkuplast® E-KV-4 is used as waterproofing sheet for flat roofs as an intermediate layer.
