Sewer Defects: From detection to new installation
When trenchless is no longer possible: Our solutions for complex cases
Sometimes a sewer system is so severely damaged that inline renovation reaches its limits. In other cases, local conditions, such as the lack of safety distance from gas pipes, prevent trenchless relocation.
It is precisely for these complex cases that we are your specialist. As a full-service provider for all sewer technology, our work always starts with a precise analysis of the situation. If the route of the line is unclear, the first step is exact channel location using a tracking device. Based on all the facts, we will then choose the most suitable process for you: horizontal drilling for trenchless relocation or, if unavoidable, professional reinstallation using an open construction method by our experienced builders.
Frequently asked questions
Here you will find answers to the most frequently asked questions about sewer defects.
Each project starts with precise analysis and planning to keep intervention as low as possible. Exact channel location using a tracking device is often the first step. Based on this analysis, we will discuss with you whether a new installation using an open design or horizontal drilling is the best solution for your situation. Only when the entire process and costs are transparent to you, do we start implementing them. As your full-service provider, we coordinate all necessary construction work.
Trenchless rehabilitation is our preferred method. However, sometimes the old pipe is too damaged due to a collapse or trenchless relocation (horizontal drilling) is not possible due to the lack of safety distance from other pipes (e.g. gas). In these cases, an open design is the best solution.
This means that we dig a ditch at the site of damage to expose the defective pipes. The old pipes are then removed and replaced by new, modern pipe systems. After a tightness test, the trench is professionally closed again and the surface is professionally restored by us.
No Our aim is always to keep the procedure as small as possible. Thanks to precise positioning technology, we limit excavation work to the absolutely necessary area. We work cleanly and efficiently and ensure that all surfaces are professionally restored 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.

From location to new installation: Our expertise for sewer defects
Channel location with tracking device
Channel location with a tracking device is always necessary when the exact course and depth of lines are unclear. This is particularly important before planned earthwork and drilling work in order to avoid expensive damage to the existing sewer system. It is the professional procedure when there are no or only inadequate construction plans, and thus ensures maximum planning security.
Overview of features:
- Range of use: Exact location of pipes before construction, earthwork or drilling work as well as locating collapses.
- main advantage: Maximum planning security and prevention of expensive damage to existing sewer systems.
- Technical details: Precise determination of the course and depth of the lines using modern tracking technology.
New installation in open construction
If trenchless renovation or relocation is not technically possible, the open construction is the professional and safe solution. As your full-service provider, we take on all sewer and builder work from a single source. This avoids coordination problems with external companies and guarantees professional repair of your sewer system.
Overview of features:
- Range of use: Re-installation or repair of pipes in the event of massive damage (e.g. collapse) or when trenchless procedures cannot be implemented.
- main advantage: You get all services from a single source — from earthwork and excavation work to replacing the pipes and restoring the surfaces.
- Technical details: Includes all construction work, including possible courtyard and basement renovations.
horizontal drilling
As far as local conditions permit, the horizontal drilling The most economical and resource-saving process for trenchless new pipes. This involves “shooting” a new channel underground, which requires only minimal surface intervention.
At Home in Austria
