SONNTAG builds underground pressure pipelines for water supply and disposal and gas supply. Depending on the requirements, HDPE, cast, or appropriately lined and coated steel pipes are used. Our range of services includes the installation of house connection and main lines.
In Berlin, we have been offering trenchless replacement since 1997 and trenchless new installation of pressure pipelines since 1998.
The methods become economically interesting compared to open construction when the surface is paved and when utility lines or root systems require a lot of manual excavation in open construction.
