Pipeline construction
SONNTAG builds underground pressure lines for water supply and drainage, and gas supply. Depending on the requirement, HDPE, cast, or appropriately lined and encased, steel pipe is used. Our range of services includes the installation of domestic supply and mains supply lines.
In Berlin, we have been offering the replacement of pressure lines since 1997 and new installations since 1998, both without the need for trenches.
Installation becomes economically viable when compared to the open-construction method if the surface is paved and if supply lines or root systems require manual trench-digging.
