GRP Pipes to withstand heavy truck traffic loads in Pécs

In 2001 and 2006 about 1.5 km of HOBAS SewerLine Pipe were laid in the prior reconstruction stages on the upper track of the main collector. Fortunately the autumn was dry and the groundwater level was far below the level of around 3 m that was assumed in a preliminary study.Finally, between September 2007 and January 2008 the construction company Platina-Bau Co. Ltd. installed further 569 m HOBAS SewerLine Pipe Systems DN 800 by open trench. The contractor connected HOBAS Sand Couplings to the Manholes for a better grip. Since the depth of trench varied between 4.5 and 5.8 m the usual 6 m standard pipes were delivered in 3 m long sections. Thanks to the centrifugal casting process of HOBAS CC-GRP Products it was also possible to cut the 6 m pipes directly on site when necessary.
