Pilot drive
DN 150 – DN 600
"Building for people and nature" is not just an empty promise at SONNTAG. Underground pipe jacking reduces the adverse effects associated with any building project and protects resources. Increasingly, smaller collectors and service connections are therefore being installed trenchless.
In this area, we work with the "pilot drive DN 150 - DN 600". First, a pilot pipe is driven through penetrable soil to the target pit under permanent observation of the direction and inclination. The pilot pipe subsequently acts as orientation for the actual bore and laying of connection pipes. Construction time is considerably less compared to open trench pipe laying.
