Horizontal Directional Drilling: Trenchless New Installation of Wastewater Pipes
Laying new pipes without excavation
Horizontal Directional Drilling is the most economical method for the trenchless new installation of wastewater pipes, especially when rehabilitation of the old pipe is no longer possible or uneconomical. It is the ideal solution when the new route runs under surfaces such as gardens, asphalted paths, or buildings that should remain untouched.Using a precisely controlled drill head, we create an underground channel that ensures the necessary gradient for the new wastewater pipe. Only a small starting and target pit are required on the surface. The areas in between remain completely intact.
Common questions about Horizontal Drilling
Here you can find answers to the most frequently asked questions about horizontal drilling.
Horizontal drilling is the ideal solution for two main scenarios. First, when your old sewage pipe is so severely damaged that trenchless renovation (such as with an inline liner) is no longer technically possible or uneconomical. Secondly, it is used when a completely new sewer connection must be created, e.g. for a new building, and the pipeline must cross surfaces such as gardens, driveways or existing buildings.
The most important requirement is sufficient space in the ground. Since we work precisely and safely, legal safety distances from other existing lines, such as electricity or gas pipes, must be maintained. Our experts therefore always check the exact circumstances first as part of an on-site analysis. Only after this feasibility check do we give final approval for the project and ensure that this is the best solution for you.
We offer a complete complete solution from a single source. Our service doesn't end with drilling. Our specialists will ensure that the new line is properly connected to the public sewer and to your house system. In addition, our team carries out all necessary builder work, from excavation of small start and finish pits to the professional restoration of all surfaces afterwards.
As soon as the new, separate line is routed horizontally, the old, defective line is no longer required. As part of our comprehensive service, we ensure that the old line is professionally shut down. As a rule, it is cleaned, permanently closed at both ends and remains securely in the ground. This avoids any risk of the soil collapsing or settling down later.
The inline process repairs and renews the existing Management from within. It is a “pipe-in-pipe” method. The horizontal hole, on the other hand, does not use the old line at all. Instead, a completely new, independent underground pipeline will be created. This is always the necessary solution when the old route is unsuitable or the damage is too great for interior renovation.

Horizontal Directional Drilling explained
Horizontal Directional Drilling
Horizontal drilling is the most economical method for trenchless new pipes, especially when it is no longer possible to renovate the old pipeline. A new channel is “shot” underground using a special drilling rig without the need to open large areas of gardens, paths or asphalted areas. All that is required is a small start and finish pit.
However, an important requirement is a sufficient safety distance from other lines, such as gas pipes. That is why our experts check the feasibility before we can make a recommendation to you and start working.
Overview of features:
- Range of use: Trenchless reinstallation of pipes when renovation is technically impossible or uneconomical.
- main advantage: The most economical form of new piping with only minimal surface intervention.
- Technical details: Suitable for re-laying pipes with a diameter of up to 500 mm.
