Sometimes a sewer system is so badly damaged that CIPP lining reaches its limits. In other cases, local conditions, such as an insufficient safety distance to gas pipes, rule out trenchless new installation.
It is precisely for these complex cases that we are your specialist. As a full-service provider for all areas of sewer technology, our work always starts with a precise analysis of the situation. If the route of the pipe is unclear, the first step is to locate it exactly using a radio sonde. Based on all the facts, we then choose the most suitable method for you: horizontal drilling for trenchless new installation or, if unavoidable, professional new installation using the open-cut method by our experienced construction team.
Here you will find answers to the most frequently asked questions about sewer defects.
Every project starts with precise analysis and planning to keep the intervention as small as possible. Often, the first step is to locate the exact route of the sewer pipe using a radio transmitter (sonde). Based on this analysis, we discuss with you whether a new installation using the open-cut method or horizontal drilling is the best solution for your situation. We only start the work once the entire process and the costs are transparent to you. As your full-service provider, we coordinate all the necessary construction work.
Trenchless rehabilitation is our preferred method. Sometimes, however, the old pipe is too badly damaged because it has collapsed, or trenchless new installation (horizontal drilling) is not possible because there is not enough safety distance to other utility lines (e.g. gas). In these cases, the open-cut method is the best solution.
This means that we dig a trench at the point of damage to expose the defective pipes. The old pipes are then removed and replaced with new, modern pipe systems. After a leak test, the trench is properly backfilled and we professionally restore the surface.
No. Our aim is always to keep the intervention as small as possible. Thanks to precise pipe location technology, we limit excavation work to the area that is absolutely necessary. We work cleanly and efficiently and professionally restore all surfaces at the end, so that as little as possible remains of the construction site.
Yes, absolutely. That is one of our biggest benefits. With us, you have a single, reliable partner who manages the entire process — from analysis and excavation work to the final restoration of the surface. This avoids coordination problems for you and guarantees the highest quality.
Locating a sewer pipe with a radio sonde (transmitter) is always necessary when the exact route and depth of pipes are unclear. This is particularly important before planned earthworks and drilling, to avoid expensive damage to the existing sewer system. It is the professional approach when there are no or only inadequate construction plans, and it ensures maximum planning reliability.
If trenchless rehabilitation or new installation is not technically possible, the open-cut method is the professional and safe solution. As your full-service provider, we handle all sewer and construction work from a single source. This saves you coordination problems with external companies and guarantees a professional repair of your sewer system.
Where local conditions permit, horizontal drilling is the most economical and resource-efficient method for installing new pipes without trenches. A new pipe route is “shot” underground, requiring only minimal intervention at the surface.
