Dörr-Tiropont® EL-2K

Shear resistant elastomer bitumen waterproofing 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 has finge granule finish and the downside is foil-laminated.

The bonding is done by means of torching or welding procedure.



Dörr-Tiropont® EL-2K is used as bitumen waterproofing sheet for bridges, parking levels and tunnels in open construction as intermediate layer sheet as well as top layer.

The bitumen sheets is externally monitored by the Technical University of Graz in accordance to  RVS 15.03.12.
