Dörr-Tiropont® EL-1 (=E-GG B)

Shear resistant elastomer bitumen waterproofing sheet with a woven glass fleece reinforcement in a thickness of 3,5 mm.


Elastomer bitumen is highly elastic ("rubbery") and thereby remains flexible even at low temperatures.
The woven glass reinforcement is dimensional stable, smooth in process and has excellent resistance to tearing.

The surface texture upside and downside has a fine granule finish.


The processing of these waterproofing sheets is done with a mopping method in which bitumen heat bonded mass (TP-HK) is used for submerging.



Dörr-Tiropont® EL-1 is used as bitumen waterproofing sheet for bridges, parking levels and tunnels in open construction as intermediate layer sheet.

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