“Building for people and nature” are not empty words at SONNTAG. Underground pipe jacking reduces the disruptions associated with each construction project and conserves resources. Therefore, smaller collectors and house connections are increasingly being installed without excavation.
In this area, we work with “pilot pipe jacking DN 150 - DN 600”. In displaceable soils, a pilot pipe is first pressed under constant optical control of direction and inclination to the target pit. The pilot pipe then serves as a guide for the actual drilling and installation of the connection pipes. The construction time is significantly reduced compared to open pipe installation.
