Dörrkuplast® E-KV-4/Perimguard

Elastomer bitumen sheet with a synthetic fleece reinforcement 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 downside is foil-laminated.
The bonding is done by means of torching or welding procedure.


The special bitumen makes the bitumen waterproofing sheet significantly smoother. The bitumen mixture and the surface texture downsides special foil facilitate the scarfing. This guarantees a quick (saving gas) and safe waterproofing of the construction. 



Dörrkuplast® E-KV-4/Perimguard is used as bitumen waterproofing sheet for building systems.
