If classic trench construction is out of the question for space, environmental or cost reasons, we rely on the most modern trenchless techniques. We protect nature and minimize restoration costs.

## Maximum Efficiency, Minimal Intervention Trenchless line laying is the smartest solution for complex construction projects. This process shows its absolute strengths particularly when crossing highly frequented roads, railway lines, highways or sensitive bodies of water. Traffic continues to flow, nature remains untouched and complex surfaces such as expensive paving or asphalt do not have to be destroyed. ## HDD Boreholes and Earth Rockets With our specialized machinery, we master a wide variety of processes. With the **Horizontal Directional Drilling (HDD) process**, we steer the drill head precisely underground. We achieve drilling lengths of up to 250 meters in one piece and can pull in protective pipes with a diameter of up to 400 mm. For shorter distances, such as fast and gentle house connections, we use our **earth rockets** (soil displacement method). Here we achieve drilling lengths of up to 15 meters for pipes up to 160 mm in diameter - ideal for leaving front gardens and driveways completely intact.
