Sewer and Pipe Rehabilitation: CIPP Lining without Excavation

With trenchless CIPP (cured-in-place pipe) lining, we repair damaged sewer lines highly efficiently from the inside. A flexible fabric liner is cured directly within the old pipe to create a durable, resilient system. Depending on the nature of the damage, we also utilize point repairs, horizontal directional drilling, or manhole rehabilitation.

What We Are Particularly Proud Of: The Feedback from Our Customers on Google

We can only recommend the company "Der Kanal"! Our sewer rehabilitation became necessary due to a sewer collapse following a storm in 2023. The repair was largely covered by insurance. However, due to its age and location, the damage was extremely complicated to repair. Everything went perfectly, from the quote, to the clarification with experts (surveyors), the work on site,
Philipp F.
Although it was Sunday shortly after midnight, the company's emergency number was immediately reachable. The employees arrived at our location within the shortest time and were able to remove the blockage in the main sewer of our facility, to which 20 houses are connected. The employees were very friendly and competent! Thank you for the quick help!
Günter S.
After the property management (HVW) likely let the repair order sit for a while, I called "Der Kanal" myself after urging them, to quickly arrange an appointment for an emergency (clogged toilet). The first positive surprise – I got an appointment for the very next morning. The friendly employee was punctual (and called to announce himself half an hour beforehand), competent, friendly, and was able to quickly find and fix the problem. Given the currently rampant shortage of skilled workers, I find this particularly noteworthy, am impressed, and can unreservedly recommend this company.
Michaela S.
Fast, friendly, competent employee. I specifically asked the employee for his name. It's rare for something to work so well. Thank you
Nicki K.
Clogged wastewater pipes on a Sunday evening. Thank God Der Kanal was on site within 30 minutes and the competent and friendly gentlemen were able to solve the problem in the shortest time. Only 5 stars because there are no more to give!
Nelli K.
The competent and friendly staff arrived on site after a short time and were able to professionally solve our problem on the same day. That's how service should be. Thank you very much for the help, dear team.
Daniel G.
Called twice already for different defects (Gebrechen), prompt and friendly response, the deployment team was on site within minutes (7th district) and delivered fast, perfect work. It is particularly noteworthy how cleanly the workers performed the job. Can only warmly recommend this company!
Wolfgang K.
Fast and clean. Real professionals and affordable too!!!
Gerhard K.
Sewer rehabilitation with CIPP liner, CCTV inspection, great work, everything wonderful, and last but not least, all very friendly employees, whether on the phone or on site! Special thanks also to Mr. Rybin and Mr. Karamarkovic!
Susanne P.
A top company! Everything first-class, nice employees. Can only recommend. Many thanks!
Franz A. B.
Best Service!
Lukas S.
What can I say: Reported a blockage in the washing machine area via email on Sunday (thus, not an emergency), received a call with an appointment on Monday, and this morning, Tuesday, the blockage was fixed by an absolutely nice and competent employee! SIMPLY TOP and definitely the company to call again in an emergency!
