Renovation by complete renewal with GRUNDOBURST 800G

In the polish capital of Warsaw an extensive investment programme has been carried out for several years now, in order to renew old drinking water pipes in succession, including the relevant house connections. The grey cast iron pipes, which are approximately 120 years old, have done their duty: strong corrosion has significantly reduced the cross-section of the pipes and caused the water quality to seriously deteriorate. Also, in numerous places, leakages were detected, pipe breakages everywhere and therefore causing high water losses. Due to the inner city structure – tight building developments in the business and residential areas, high traffic density, very busy streets – the trenchless method was the only solution for this pipe renewal task.
